  New terms such as embodied intelligence, 6G, and intelligent robots were first proposed in this year's government work report; Lou Qinjian, spokesman of the Third Session of the 14th National People's Congress, praised DeepSeek; Robot journalists join the news coverage of the National People's Congress and Chinese People's Political Consultative Conference... At the ongoing National People's Political Consultative Conference, artificial intelligence (AI) frequently appears and becomes one of the hot topics.   General Secretary Xi Jinping pointed out that whoever can seize the opportunities of new economic development such as big data and artificial intelligence will have the pulse of the times. In recent years, artificial intelligence has flourished at an unprecedented speed and has penetrated into many industries. For the energy industry, embracing artificial intelligence is an inevitable choice to keep up with the development of the times. Under the wave of digitization and intelligence, how can the energy industry implement the "AI+" action with high standards and high quality, promote the deep integration of AI and energy transformation and development, cultivate new growth points, and move towards a sustainable future? Around these contents, representatives and members of the two sessions from the energy sector have provided suggestions and jointly explored new paths for industry development.   Empowering the energy industry with artificial intelligence to accelerate growth requires continuous efforts in expanding and enriching application scenarios   The ultimate manifestation of 'artificial intelligence+' is through rich scenario applications. Without scenario applications, the development of artificial intelligence lacks a starting point, foothold, and vitality. Song Hailiang, a member of the National Committee of the Chinese People's Political Consultative Conference, Secretary of the Party Committee and Chairman of China Energy Construction Group Co., Ltd., believes that the integration of "artificial intelligence+" and "energy+" is constantly emerging, and the deep integration of the two will give birth to new industries, new formats, and new models, effectively promoting the improvement of production quality.   The first joint station indoor and outdoor "intelligent inspection robot" in Daqing Oilfield has been put into use in the third oil production plant.

  Recently, in the Guoxin Energy Storage and Power Generation Project undertaken by the Magnetic Guidance Team of the Engineering Technology Research Institute, the An26-2 well achieved one-time re-entry into the old cavity operation, marking the innovative application of MGD passive magnetic guidance technology in the field of compressed air energy storage by the Engineering Technology Research Institute. The Guoxin Energy Storage and Power Generation Project is currently the largest and most efficient compressed air energy storage project under construction in China. The target vertical well for this implementation has a minimum radius of 27 meters for the bottom old cavity. Drilling the injection production directional well An 26-2 near the target well requires precise control of the wellbore trajectory before entering the old cavity, and current general technology is difficult to meet project requirements.   The passive magnetic guidance technology team bravely took on the heavy responsibility and faced new technical challenges such as high conductivity of salt water, salt layer shielding excitation, and continuous underground interference. Technical experts focused on technical difficulties, conducted field surveys of adjacent wells, utilized successful experience, repeatedly optimized the plan, and developed a wide differential domain magnetic guidance probe tube with targeted research and development. In one fell swoop, they overcame technical problems such as high conductivity in salt layers, interference in measurement data, and non centering of conventional probes in large wellbores.   In on-site operations, the anti-interference ability of wide differential field magnetic guided probes is significantly enhanced compared to conventional probes. Technicians used the target well to release stimulation, thereby eliminating the interference of disordered electric fields in saline water and achieving high-precision measurement in the salt layer environment. Successfully identified and captured the target signal in a short period of time, accurately predicted that the target well would re-enter the old cavity at 1276 to 1278 meters, and the actual error was less than 2 meters. Next, the magnetic guidance team of the Engineering Technology Research Institute will continue to make breakthroughs in MGD passive magnetic guidance technology in practical operations, contributing technical strength to national engineering construction projects.

    On November 8th, it was learned from Bohai Drilling Company that the company's self-developed 1.25 gram per cubic meter ultra-low density cement slurry system was successfully tested for the first time in the Ning72-81X well of the "ballast stone" project in Huabei Oilfield, and the cement slurry returned to the surface. According to electrical testing interpretation, the cementing quality is qualified, breaking the record for the lowest cement slurry density in Huabei Oilfield cementing.     The Ning 72-81X well is a development well deployed in the Suning block of Huabei Oilfield, with a total drilling depth of 3899 meters. Due to the weak pressure bearing capacity of the formation in this well, drilling fluid with a density of 1.25 to 1.26 grams per cubic meter is required to complete the drilling. In order to ensure that the cementing slurry can be sealed for more than 3000 meters at once and returned to the surface, Bohai Drilling actively organized technical experts to carry out cementing technology discussions, and determined to adopt a technical solution that the density of the cement slurry in the upper wellbore section is not higher than the density of the actual drilling fluid. While ensuring pressure stability, the maximum reduction of liquid column pressure is achieved, laying the foundation for this cementing construction. During the construction period, the on-site construction personnel of Bohai Drilling strictly controlled the construction details and successfully completed various cementing construction indicators. This marks the successful testing of the company's self-developed ultra-low density cement slurry system, providing a new solution for cementing long sealing sections in easily lost formations in various markets in the future.

  On October 12th, the reporter learned from Great Wall Drilling Company that the coal seam gas company Jishen 6-3 platform 01 well, which was drilled by the company's drilling company, has been successfully completed, 12 days ahead of the design cycle, and the coal seam drilling encounter rate has reached 100%. The well has been drilled to a depth of 4550 meters and a length of 2140 meters per trip, breaking the record for the longest drilling depth of a deep coalbed methane horizontal well in China and marking a new breakthrough in the exploration and development of deep coalbed methane by PetroChina.     The Jishen 6-3 platform is the first deep coalbed methane platform deployed by a coalbed methane company with a horizontal section length exceeding 2000 meters. Since the launch of the platform, Great Wall Drilling has deepened the integration of Party A and Party B, integrated geological engineering and other efficient operation mechanisms, repeatedly demonstrated construction plans and polished technologies, iteratively upgraded trajectory control, wellbore stability and other processes, innovatively applied wellbore cleaning technology and near drill bit geological guidance system, and used real drilling natural gamma curves for real-time analysis of lithology changes. Fine tuning the performance of drilling fluid to enhance its sealing and anti collapse capabilities effectively addresses challenges such as larger off target distances and higher construction difficulties, extending the length of one drilling trip from 2097 meters to 2140 meters. Vigorously promote the use of highly aggressive drill bits, high torque long-life screws, hydraulic oscillators and other acceleration tools to lay the foundation for safe, high-quality and fast drilling, and promote further acceleration and efficiency improvement of deep coalbed methane horizontal wells

The existing measuring devices upstream of the screw cannot obtain real data at the position of the drill bit, and intelligent drilling has serious data bias and unpredictable implementation risks at the decision-making and control level. For this purpose, a probe type intelligent drill bit parameter measurement device (see Figure 1) has been developed, which can be installed inside the drill bit to directly collect real data at the drill bit without changing the existing drilling tool combination and construction process; The hardware structure simulation optimization results show that under a displacement of 30L/s and an annular pressure of 80MPa, the theoretical hydraulic pressure consumption is less than 0.1MPa and the safety factor is 3.06. Meanwhile, based on the six sided method and ARMA+mobile Kalman filtering, the error calibration and noise reduction of the device were achieved. The device was tested 9 times on site in the Shengli work area, and the downhole engineering parameter measurement short section was used for device function verification and comparison with downhole data. The comprehensive logging data was integrated for the acceleration analysis and parameter optimization decision-making of the test well. The experimental results show that the probe type intelligent drill bit parameter measurement device can obtain real data at the drill bit position, which can provide reliable basis for targeted acceleration and efficiency analysis and drilling parameter optimization. The article "Development and Field Testing of Intelligent Drill Bit Parameter Measurement Device with Probe Tube" (Author: Huang Zhe) has been published in the 4th issue of "Petroleum Drilling Technology" in 2024

Bohai Drilling Company is closely focused on accelerating the construction of a world-class international oil service enterprise, and regards the vigorous promotion of the "one trip drilling" project as an important lever for speeding up and improving efficiency. It continuously improves the combination of "one trip drilling" characteristic technologies and construction plans for different regions, formations, and well sections, and summarizes and promotes the best operational practices of "one trip drilling". In the first half of this year, Bohai Drilling completed 232 drilling operations at depths of over 2000 meters in various markets, accounting for 42.34% of the total.   Fine Production Organization   Steadily advancing the 'one trip drill'   One trip drilling "refers to a drill bit that completes one opening or section of the well in one go, achieving the goal of shortening the construction period and improving quality and efficiency. Implementing 'one trip drilling' is a systematic project that requires not only advanced and efficient technology, but also collaboration among teams. In response to this, Bohai Drilling Company has started with top-level design, forming a top-down linkage and joint management mechanism with leaders taking the lead, production and technology departments leading, administrative logistics support, and frontline teams implementing. Together, they have formulated a "one trip drilling" implementation plan and steadily promoted the implementation of the "one trip drilling" results.   For wells that can implement the "one trip drilling" project, Bohai Drilling follows the "four requirements" model, which includes "detailed preparation of each process, reasonable work steps, advanced material planning, and meeting work quality standards". It deepens the lean drilling production organization, refines the opening connection from multiple dimensions, quantifies the time of each process, minimizes auxiliary operation time, and forms a set of efficient production organization and smooth process connection work modes.   In the construction of the JHW82-32 shale oil well in Jiqing, Bohai Drilling's various construction units finely organized production, highlighted advanced and rigorous methods, communicated and coordinated with cooperating parties in advance to speed up tools, ensured ground equipment support, and maximized production efficiency, achieving the goal of "two drilling and horizontal sections" and "one drilling" completion, setting two records for the shortest drilling cycle and completion cycle of oil wells deeper than 5500 meters in the Jiqing market.   Strive for excellence in technology   Assist in the implementation of 'One Trip Drilling'   Since the beginning of this year, the Bohai Drilling "One Trip Drilling" project has continuously made new breakthroughs, and the technical research team has played an indispensable role. High quality and efficient drill bits are powerful tools for achieving 'one trip drilling'. The combination of drilling tools, the use of tools and instruments, the selection of drilling parameters, the optimization of drilling fluid system performance, and the control of wellbore trajectory are all important factors in assisting 'one trip drilling', "said Chen Tian, a technician at Bohai Drilling Company     According to the concept of "one well, one strategy, one section, one method, and one layer, one move", Bohai Drilling arranged technical experts to provide on-site guidance, starting from geological characteristics, process measures, etc., taking profiles, targets, and actual drilling trajectories as research objects, analyzing the differences between completing wells with "one trip" and combining with the actual construction of single wells and blocks, continuously refining drilling pressure, pump pressure, and displacement
