Successful completion of the first autonomous daily exploratory well in North China Oil & Gas

Sinopec News Network reported on June 29 that the first autonomous daily exploratory well of North China Oil & Gas Branch, Xin 602, was successfully completed, setting a total of 13 speed-up records in the Xinzhao block
.

As a key project in the oil and gas and new energy sector of the group company, the new 602 well daily fee system pilot is an important exploration of the market-oriented operation of the daily fee drilling contracting model, and also an important attempt for the company's efficient exploration technology requirements and exploratory well management mode
.

The well was completed at a depth of 3860 meters, encountered a reservoir sand body of 35.
3 meters, the highest total hydrocarbon reached 11.
8%, and the core rate reached 100%, which verified that the Shanxi Formation reservoir in this block is well developed and has high production potential
.

The drilling cycle of the well was 20.
42 days, which was 6.
29 days shorter than the record of exploratory wells in the same block; the ROP reached 16.
54 m/h, which was 28.
6% higher than the average ROP of exploratory wells in the Xinzhao block; the completion period was 23.
9 days, the Chuangxinzhao block Record of the shortest drilling and completion period for exploratory wells
.

Through the independent daily fee system management model, flat daily fee system pilot management, based on the integration of engineering geology, and the integration of new adaptive engineering technology technologies, the company's drilling model has been changed from Party A supervision to Party A leading and further to independent implementation.
Transform and upgrade, and form a complete set of technology + operation + management data packages based on key well drilling and completion projects
