6365 Meters! Jiqing Shale Oil Deepest Well Record Set

Refined production organization, strict compliance with operating procedures, timely adjustment of technical measures according to different well sections, different formation lithologies, and different working conditions, starting with details, strictly controlling construction quality, overcoming formation construction difficulties, and completing construction tasks with high efficiency and high quality. 7 tubes were successfully cored, with a core length of 94.33 meters and a harvest rate of 99.6%, which was well received by Party A.

During the construction, this team gave full play to the integrated cooperation of engineering geology, deepened the well type drilling, and optimized the "one section, one method" optimization measures. In view of the problems such as the second-opening breathing formation and tripping jam, it accurately implemented the step-by-step control of drilling fluid density. Optimize mud solutions such as improving blocking and suppression capabilities to effectively solve technical bottlenecks. Optimize trajectory parameters, focus on process control, firmly block the "bleeding points" of complex accidents, and ensure that both well quality and steering efficiency are improved.

Focusing on the key cementing operations, this team carefully sorted out the cementing procedures and implemented the requirements of the cementing association. From the insulation of the cementing water to the transportation and placement of the mixed slurry returned from the cementing and the transportation and placement of the cement slurry, the team decomposed each link, and Carry out detailed analysis and personnel monitoring and deployment of risks during construction and on-site construction conditions. During the construction, team cadres were arranged for all-round and full-process monitoring at each link. The entire cementing construction process was safe and continuous, and the first horizontal well in the block was successfully returned to the ground with cement.
