Recently, it was learned from the Changqing Gas Field Drilling Technology Symposium held by the Changqing Petroleum Exploration Bureau Drilling Corporation that this year, in the face of the heavy capacity building task of the gas field, the company carried out the test and promotion of new technologies such as PDC bit and screw drilling tools. Application, to achieve a substantial increase in drilling production.

This company carefully analyzes the technical problems in the exploration and development of gas fields, and overcomes the bottleneck that restricts the drilling speed as a breakthrough. According to the characteristics of different well types, various research tests are carried out to speed up the drilling speed. According to different well types, the drilling fluid performance is optimized, which not only solves the anti-collapse and plugging ability of the well, but also liberates the mechanical drilling speed to the maximum extent, improves the drilling speed, and continuously refreshes the production index, creating 8 items. Gas field drilling production indicators.

At the same time, the company organized technical personnel to complete the research on “Changqing gas field optimization technology for natural gas drilling” and “Extension application of solid-free drilling fluid system in natural wells”. These scientific research results are solved after being applied in production. The technical problems in production provide a strong technical guarantee for safe and fast operation of drilling production.

As of December 15, this year, the company completed a total of 601,909,000 meters of gas wells, 207 gas wells and 208 gas wells per year.
