On June 24th, the Red Page 2HF well, which was drilled by the 70210JH drilling crew of Jianghan Petroleum Engineering Company No.
The well is a pre-exploration well for the Jiannan geological structure of the Shizhu compound syncline in the high-steep fold belt in the east of the Sichuan Basin.
In order to ensure the smooth progress of the well construction, the company selected experts and technical backbones to guide the well, adhering to the principles of "one well, one strategy," "one trip, one strategy," and "one section, one strategy", to formulate special technical measures for different layers Parameter optimization and drilling tool optimization
The 70210JH drilling crew that drilled the well strictly implemented operating instructions, technical measures and safety operating procedures, rationally organized production and operation, adopted a refined model, and formed a safety management pattern featuring comprehensive management, full process control, and full participation
In view of the strong abrasiveness of the formation section and the horizontal section, and the short life of a single bit, the team has successively adopted new technologies such as hybrid bit + screw, imported PDC bit + spinner + screw, long horizontal section oil-based drilling fluid optimization, etc.
There are 7 cores in this well, and the core harvest rate is 98.
