On August 2, the Bao 8-1 Ping 3 well located in Fugu County, Shaanxi Province, was successfully drilled to 1,711 meters, marking the first 100 million cubic meters of coal-bed methane development project on a large scale in China to complete the drilling task efficiently
.

The Bao 8 coalbed methane development project is a coalbed methane rolling edge expansion project deployed by CNPC CBM in the Baode block of the Edong gas field
.

Exploration data show that there are two main coal seams developed in this area, No.
4+5 and No.
8+9.

On this basis, the geology and engineering technicians of the CBM company have gone through 10 on-site surveys and 11 rounds of optimized deployment, and compiled the first domestic development plan for a large CBM platform with a capacity of 100 million cubic meters
.

The plan is developed in the form of 4 large-platform horizontal wells with long horizontal sections to solve the problem of difficult development of urban overlying coalbed methane resources

At present, the 35 cluster wells of the Bao 8 CBM development project have a coal seam encounter rate of 100%.

The average horizontal section of 20 horizontal wells is 976 meters long.
The coal seam encounter rate has reached 98.
