Jianghan Oilfield Makes a Major Breakthrough in E'e Exploration Enshi Discovers 100 billion square meters of shale gas resources

On January 13, Longtouxi Village, Jiannan Town, Lichuan City, Enshi Prefecture, Hubei Province, the Red Page 2HF well was continuously tested for 15 days, and the Nissan shale gas was controlled at 65,000 cubic meters, and the test daily gas production reached 128,000 cubic meters
.

The Hongsha 2HF well is the second shale gas pre-exploration well deployed in the Permian system in the Hongxing area of Lichuan City after the Hongsha 1HF well
.

"The red page 1HF well successfully completed the trial mining, filling the gap
in the exploration and development of Permian shale gas in China.
The continuous deployment of red page 2HF wells and red page 3HF wells with good oil and gas drilling shows that they have made a major breakthrough
in shale gas exploration in the region.
Guo Zhanfeng, manager of the exploration and management department of Sinopec Jianghan Oilfield, introduced that Jianghan Oilfield has successfully submitted the first batch of Permian shale gas forecast reserves of 105.
1 billion cubic meters
in the Hongxing area.
Last month, the relevant achievements won the special prize of Sinopec's 2021 Major Discovery in Oil and Gas Exploration
.

In the 1960s and 1970s, Jianghan Oilfield discovered the Jiannan Gas Field
in Lichuan Exploration.
However, for a long time, Jianghan Oilfield has not made a major breakthrough in the exploration and development of this block, and only conventional natural gas
is extracted.

In 2016, researchers proposed the deployment of shale gas risk exploration wells in the Red Star Permian
wells Red Page 1HF.
In November 2019, the well guide hole was officially drilled
.
Chen Xiaogang, director of the Exploration and Development Research Institute of Jianghan Oilfield No.
1 Gas Production Plant, introduced that due to the limited accuracy of geological data and the thin shale reservoir, it is very
difficult to guide the geological guidance of the horizontal section of the red page 1HF well.
During the drilling process, the researchers of Jianghan Oilfield used the gamma measurement system with drilling to carry out real-time reservoir tracking comparison and model calculation, and timely adjust the drilling trajectory
.
In the end, the well's high-quality shale gas layer drilling rate reached 95.
6%.

In October 2020, the Red Page 1HF well began trial production, and the cumulative gas production exceeded 20 million cubic meters in more than a year, which is the highest cumulative shale gas well
in Hubei Province.

Sun Jianfa, secretary of the party committee and senior engineer of the first gas production plant in Jianghan Oilfield, introduced that the predicted gas storage area of the first batch of Permian gas in the Hongxing area is 343 square kilometers
.
The local shale gas storage range is much larger than this area
.
It is estimated that the shale gas resources buried within 4500 meters of the area are more than 400 billion cubic meters, which has broad prospects for
commercial development.
