my country's maritime shale oil exploration has made major breakthroughs

Our newspaper, Beijing, July 28 (Reporter Qiu Yan) It was learned from China Sea Oil that on July 28, the first shale oil exploration of the first section of my country's maritime-1 well-1 well was successful and the commercial oil flow was obtained. He has made major breakthroughs in my country's maritime shale oil exploration.

The 于 涠 涠 涠 涠 is located in the southwest of the northwater area of ​​the South China Sea. Nissan crude oil is 20 cubic meters, the natural gas is 1589 cubic meters, and the production capacity is stable. According to estimates, the amount of shale oil resources in the southwest of the southwest of reached 800 million tons, and the number of shale oil resources in the Beibu Gulf Basin was about 1.2 billion tons, showing a good prospect of exploration.

It is understood that shale oil mainly refers to the oil resources distributed in the pores of shale stratigraphy, which is a typical unconventional oil and gas, and it is also a strategic replacement area for conventional oil and gas. Compared with conventional oil and gas, the hidden oil pores of shale oil are as small as nano -level, which is extremely difficult to harvest.

In recent years, as the regular oil and gas development of the old oil field enters the middle and late stages, China Oil has regarded unconventional oil and gas exploration and development as an important direction for resource replacement and stable production. According to Deng Yong, the general geologist of China Sea Oil Zhanjiang Branch, during the process of research, the Chinese sea oil project team innovated the "conventional and unconventional integration" exploration ideas, repeatedly studied the characteristics of the geological collection of southwest shale oil oil, and multiple rounds. Research projects and fracture feasibility, ultimately preferred target areas with good oily and fractured transformation, and deployed the 涠 论-1 well.

In response to the geological characteristics of the sandy strip zone of the fracture layer of the target area, the project team adopts the "high and low viscosity integrated seawater -based adhesive compression fissure system+current limitsholehole+control pressure return" special fracture process to release production capacity. The test operations of the two types of shale oil section of interoperability and mezzanine type have been found in business discovery.

Xu Changgui, general manager of China Sea Oil Survey Department, said that the success of the first shale oil at sea is a major breakthrough in maritime oil and gas exploration, and realized the use of our own equipment and technology to develop independently of my country The prelude of unconventional oil and gas exploration and development has huge resources. In order to make the rice bowl of energy, it consolidates the resource foundation in its own hands.
