Abstract

Abstract: In the Sichuan Basin, the geologic survey on shale gas began in 2006, the construction of the state shale gas demonstration area commenced in 2012, and large-scale productivity construction was carried out in 2014. Through a series of systematic researches, the concept of integration has been actively practiced, and the innovative applicability model has been built for shale gas exploration and development. Accordingly, a geology-engineering integration platform has been created, and an intelligent shale gas field has been set up. Guided by the concept of geology-engineering integration, the Changning State Shale Gas Demonstration Area with a comprehensive productivity of 15×10⁸ m³/a has been built, which provides a new direction, new idea, new path and new prospect for CNPC's green and efficient development of shale gas. With referent to the successful unconventional oil and gas development in North America, and depending on the complex surface and subsurface conditions in the Sichuan Basin, the large-scale development of shale gas was realized, and the comprehensive benefit was continuously enhanced, through a series of deployment and exploratory attempts. In this process, a set of relatively complete and specific development model for marine shale gas in China was formed. This model has facilitated the Changning State Shale Gas Demonstration Area to become an outstanding area in China for unconventional oil and gas exploitation, with its single-well productivity gradually improved and comprehensive benefit steadily optimized.

Key words: geology-engineering integration, shale gas, penta-model, intelligent shale gas field, big data
