Due to the multi-stage tectonic movement, the geological conditions of shale in Nanchuan are complex and resource endowment is deteriorating, which makes it difficult to realize the scale economy development. In order to actively promote the beneficial development of Nanchuan shale gas, it insists on the development concept of geological engineering integration and all-around whole-process optimization, and carries out comprehensive research on “research deployment, well pattern optimization, drilling engineering and fracturing engineering” and other aspects. According to the principle of fully utilizing underground resources and optimizing before surface drilling, the optimal deployment of drilling platform and well pattern is determined. The well placement design is optimized with productivity sweet spot as the core, meanwhile, the integrated steering technology is applied to achieve precise penetration and improve sweet spot penetration. Aiming at maximizing the complexity of fracture network and productivity, the fracturing process design is optimized to maximize the benefits of shale gas wells. Based on the production, construction and implementation of shale gas in Nanchuan area, an integrated model of the whole process of “research, deployment, design, implementation and support” has been formed under the characteristics of Nanchuan complex structural belt, which can improve the drilling speed and fracturing production, and promote the beneficial development of shale gas in Nanchuan area.

Key words: normal pressure shale gas, geology-engineering integration, optimization, beneficial development, intelligent, Nanchuan Shale Gas Field
