10. 3000-meter ultra-long horizontal well drilling and completion technology combined with focused fracturing technology support the efficient development of coal and rock gas resources

针对深层煤岩气开发面临的井壁易垮塌、压裂成本高等挑战，中国石油创新形成超长水平井钻完井技术，建成国内首口3000米超长水平段煤岩气水平井，构建“聚集能量＋控液控砂＋高效铺置”聚能压裂技术，有效支撑鄂尔多斯盆地深层煤岩气规模建产，为中国煤岩气高效开发提供了关键技术引领。

In response to the challenges such as prone well wall collapse and high fracturing costs faced in the development of deep coalbed methane, China National Petroleum Corporation innovatively developed a technology for ultra-long horizontal well drilling and completion. They constructed the first 3,000-meter ultra-long horizontal section coalbed methane horizontal well in China, and established the "collecting energy + controlling fluid and sand + efficient placement" energy-concentrating fracturing technology. This effectively supported the large-scale production of deep coalbed methane in the Ordos Basin and provided key technological leadership for the efficient development of coalbed methane in China.

Main innovations and breakthroughs: (1) The structural feature of "cracks but not fractures" in coal rock was discovered. A model considering the weakening of mechanical parameters and the evolution of fractures for the stability of coal rock and interbedded shale well walls was established. A strong and stable drilling fluid system was developed, thus solving the technical problem of well wall stability in ultra-long horizontal sections. (2) A multi-source information fusion guidance decision-making mode based on coal rock gamma rays, drillability and drilling parameters was innovatively formed. A decision-making system was established to achieve "centimeter-level" precise control of wellbore trajectory, and the reservoir drilling encounter rate was increased to 98%. (3) The concept of sandless fracturing was innovatively proposed. It was clearly stated that under the action of high-pressure fluids, coal rock can fracture through "shear + slip", generating effective flow channels, providing a theoretical basis for cost reduction and efficiency improvement. (4) A cluster energy fracturing technology system was constructed. An optimization design method centered on optimizing cluster perforation, crack initiation and extension, and spacing optimization was established, maximizing the recovery degree of reserves.

该技术共申请发明专利9件，发表高水平论文7篇。实现3000米水平段“一趟钻”、钻井周期6．41天、平均机速29．33米/小时，刷新了全球深层煤岩气水平井水垂比最大、水平段最长、“一趟钻”进尺最多、机械钻速最快等多项纪录；经聚能压裂后，单井千米水平段日产气3．9万立方米，较邻井提产12％，同时总液量降低13％、加砂量减少21％，经济效益显著。

This technology has applied for 9 invention patents and published 7 high-level papers. It achieved "one-time drilling" at a depth of 3,000 meters, with a drilling cycle of 6.41 days and an average drilling speed of 29.33 meters per hour. This has broken several records worldwide, including the largest water-to-length ratio of deep coal rock gas horizontal wells, the longest horizontal section, the largest amount of drilling in one operation, and the fastest mechanical drilling speed. After pressure fracturing, the daily gas production of a single well in the 1,000-meter horizontal section reached 39,000 cubic meters, increasing by 12% compared to adjacent wells. At the same time, the total fluid volume decreased by 13% and the sand addition volume reduced by 21%, resulting in significant economic benefits.
