my country increases the "home bottom" of trillion squares of shale gas resources

Sinopec deep shale gas exploration attack has won major breakthroughs

On June 30, the reporter learned from the Sinopec News Office that Sinopec's new page 1 in Chongqing Lajiang River received 530,000 cubic meters of Nissan rock gas. The complex structure of the southeast of Sinopecchuan Basin Bottom Bandbuch New Southern — Dongxi -Dingshan -Forest Farm formed an overall continuous film, with the overall resource volume of 11930.5 billion cubic meters, becoming the second 10,000 10,000 10,000 to Sinopec after Fuling Shark gas fields. Yifang shale gas resource position.

According to reports, the new page 1 is 5,756 meters deep. It is a deep shale gas risk exploration of the Sinopec Exploration Branch deployed in the new construction structure of the new field in Chongqing. The new construction structure belongs to the complex structure belt of the southeast of Sichuan Southeast Sichuan. Earlier research showed that the constructor's ultra -deep shale gas has a large area of ​​large shale gas and large resources, which is an important area for China Petrochemical shale gas storage and production.

The reporter learned that the average depth of the Xinchang South -Dongxi -Dingshan -Forest Farm was greater than 3500 meters, and the deepest diced pages 8 of them reached 4614 meters. Generally speaking, shale gas with a depth of more than 3500 meters is defined as deep shale gas. There are many floors through deep shale gas, and there are many world -class problems such as shale burial deep and complex ground stress. It has high technical requirements and difficult exploration and development. If the shallow shale gas development is to expand the "sheep intestine trail" into a "highway", then the deep shale gas development is to open a bridge on the Qinghai -Tibet Plateau to build a complex "Panshan Highway".

After China Petrochemical made a major exploration breakthrough in Fuling Shalefield Gas Field in 2012, he turned his attention to the complex structural belt of the southeast of Sichuan, set up a deep shale gas technology research group, and continued to carry out technical research such as deep shale gas target evaluation. The deep shale gas volume fracture technology has achieved 100%of the high -quality shale drill rate, and the fracture equipment, tools and materials are all realized, greatly reducing construction costs. In 2019, a strategic breakthrough of deep shale gas exploration was obtained. After that, the deep shale gas exploration was further promoted, and the trillion -square shale gas resource position was implemented.

In the deep shale gas exploration and attack, Sinopec Innovation has formed the theoretical technology of deep shale gas exploration. In 2017, Sinopec established a deep shale gas research leadership group and Dongxi structured deep shale gas research area, and concentrated on the development of theoretical and technical research. After years of comprehensive research and research and exploration practice, the awareness of deep shale gas geological theory has been formed, and the deep shale pore development and maintenance mechanism of deep water shacks is successfully revealed. The key element of dessert goals, etc.; Formation of deep shale gas dessert predictive technology, proposing "high -quality shale development, high -current pressure, development of micro -cracks, low ground stress" is the key element of deep dessert evaluation. Innovation forms a high -precision earthquake exploration based on high -precision earthquake exploration Dessert prediction technology; formation of deep shale gas fracture engineering technology, effectively solving the problems of deep shale burial deep, strong plasticity, high ground stress, and difficult to fracture. Pressure extension, balanced extension, and "stubborn mesh fracture technology.

Sinopec stated that it will strengthen the detailed evaluation of the new construction goals, strengthen the overall evaluation and deployment of the "Southern -Dongxi -Dingshan -Liangcun North" in the southeast of Sichuan, and strive to achieve a breakthrough in new exploration.
