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.
