Near bit Geosteering Drilling System
The Geo-Steering Drilling System-Near Bit (CGDS) is the first near-bit geosteering drilling system with independent intellectual property rights in China, which directly serves the measuring-while-drilling technology in geological exploration and can improve the discovery rate of exploration well, suitable for drilling and development of complex formation and thin oil layer, as well as key wells, important well sections, well sections with unclear formation distribution and horizontal wells with thin oil layer.
Technical Features: It is suitable for oil and gas exploration wells, horizontal wells and multi-branch wells, ESPecially for complex formations and thin oil layer development wells. It can improve the success rate of exploration wells, the drilling rate and recovery rate of oil layers in development wells, and has the three major functions of Measurement, transmission and steering.
Field Application: In recent years, the Near-bit Geosteering Drilling System is suitable for small and conventional holes. It has been successfully applied in 22 oil fields such as Daqing Oilfield, Jilin Oilfield, Xinjiang Mahu Lake, Tuha and Changqing tight oil and gas horizontal wells, Jianghan Oilfield, Zhejiang Oilfield, Shengli Oilfield and those in Canada, with a successful application of 328 well-times, and a total drilling depth of more than 400 km. Meanwhile, the system has become the first geosteering system to pass the API Q2 certification in China, with which BPM can help to provide more standard and qualified service for clients all over the world.
Technology Core: It is near. Reservoir boundary is discovered early and well trajectory is adjusted timely; it is stable, assembled with downhole Motor, with high steering ability and long service life; it is accurate. The resistivity, gamma dual parameter measurement, and accurate formation judgment are accurate.
Application Effect: The high-level well drilling encounter rate reduces drilling time, shortens the drilling cycle, and improves the development efficiency of horizontal well oil and gas layers.
