Normal pressure shale gas is one of the main types of shale gas exploration and development in China. It has great resource potential and broad prospects. In recent years

Sinopec East China Oil and Gas Company has continued to carry out normal pressure shale gas exploration and practice in Nanchuan-Wulong area of the basin-margin transition zone in southeastern Chongqing. Positive progress has been made in the following aspects such as basic geological theory research

low cost engineering technology research

green mine construction of normal pressure shale gas. The enrichment and high yield geological theory of “three factors controlling gas”

and the classification and evaluation standard and the target evaluation system of shale reservoirs are established. Six low cost engineering technologies of normal pressure shale gas are proposed

that is

low density 3D seismic exploration

well completion at the “second” section

“drop ball steering+continuous sand addition”

“three steps” fracturing sand addition

electric fracturing and high efficiency drainage gas production. The development technology strategy of normal pressure shale gas is preliminarily formed. The integrated green exploration and development mode is put forward. More breakthrough and efficient development of normal pressure shale gas exploration are realized. Normal pressure shale gas shows a good prospect of exploration and development. However

the exploration and development of normal pressure shale gas in China is still in its infancy and exploration stage. There are still many challenges in aspects such as theoretical innovation

technological breakthrough and benefit development. So that five countermeasures are proposed for the development of China’s normal pressure shale gas industry: ①deepen the research on the main controlling factors of shale gas enrichment and high-yield

and strengthen the target evaluation; ②speed up the research on the supporting technology of excellent drilling and completion for the further acceleration and efficiency increasing; ③strengthen the research on high-efficiency fracturing technology to increase production

reduce cost and increase efficiency; ④strengthen the research on the production rule of normal pressure shale gas

and formulate the technical strategy of benefit development; ⑤fully implement the integrated operation mode of shale gas geological engineering

improve the management quality and create benefit. These countermeasures are counted on accelerating the development of normal pressure shale gas industry in China.
