CBM Companies Had a Record Crack in Deep Horizontal Wells

As of August 21,8 deep CBM horizontal Wells of Jishen 12-8 platform of CBM Company have been continuously discharged for 15 days, with good gas effect. In early August, 8 deep CBM horizontal Wells on Jishen 12-8 platform were successfully completed, creating the world record of fracturing Wells on the same platform; after 22.3 hours of continuous and efficient fracturing, breaking the world record of the most deep CBM horizontal Wells in a single day.

Jishen 12-8 platform is the largest deep CBM horizontal well development platform deployed by the company in Daji Block. For the first time, CBM has deployed eight deep horizontal Wells on a single platform, with unprecedented difficulty and complexity.

Before the operation, in view of the factors such as difficult construction and complex road conditions, the CBM company organized many discussions, carefully optimized the operation plan, and did the material reserve and testing work in advance, to provide strong support for the efficient and continuous construction. During the construction, the pumping bridge plug poration + optical casing pump volume fracturing process was adopted to build an integrated comprehensive treatment system of "collection, transportation, treatment and reuse", and the "factory zipper" assembly line operation was carried out, improving the construction efficiency by more than 3 times. The company establishes the working mechanism of "special work group + meeting" to grasp the operation difficulties and risk points in real time, implement the double disclosure of "safety + technology"; take on duty 24 hours, monitor the whole process, and optimize the parameters in real time to ensure the smooth construction.
