Successful completion of the first shale gas risk well in Zhongyuan Oilfield

Sinopec News Network reported on August 8, the first shale gas risk well-Puluye 1 well, deployed and implemented by the Puguang Exploration Research Institute of the Zhongyuan Oilfield Exploration and Development Research Institute, was successfully completed and encountered a continuous shale gas layer 1493.
Meters, the shale reservoir encounter rate is 100%, and gas surveys show that the total hydrocarbon is as high as 88.
698%, marking a breakthrough in the exploration of the continental shale gas field in the Puguang Exploration Area
.

The Puluye 1 well is a risk well deployed on the Puguang East syncline.
The target layer is the shale of the first member of the Jurassic Qianfoya Formation.
Researchers follow the idea of ​​“coring evaluation in the pilot hole section and exploring productivity in the horizontal section”.
Deployment and implementation
.

In May of this year, the horizontal section of the well was sidetracked from 2,955 meters, and the drilling depth was 5041 meters.
The horizontal section was 1431 meters long.
A total of 1,493 meters of continuous gray-black shale was drilled in the skew section and the horizontal section.
The reservoir encounter rate 100%, gas survey shows active, total hydrocarbon is 0.
96-88.
698%, average value is 9.
68%, 10-30% pinhole bubbles are generally seen on the groove surface during drilling
.

　　The successful drilling of the Puluye 1 well has pointed out the direction for the exploration and development of the continental shale gas field in the Puguang Exploration Area of ​​the Zhongyuan Oilfield, and has further consolidated the resource base for the long-term stable production of the Puguang Gas Field
