Shale gas development is in an important position of natural gas development strategy for Sinopec

and numerical simulation technology is an important technical means to optimize the policy and scheme of development technology

predict the production performance of gas wells

study the production rule

and track and optimize the development of gas fields. The traditional numerical simulation method of shale gas development adopts equivalent medium model

can not depict the distribution of crack network after fracturing

and is unable to accurately predict the production of layered reserves

so that it can not meet the needs of the field. Therefore

a new method for shale gas simulation based on embedded fracture modeling is proposed. This method consists with four stages:①to establish geological structure model; ②to describe the fracture characteristics of the fracture network based on micro-seismic data

and then embed it in the geological model background grid and calculate the conductivity; ③to fit the production data and adjust the fracture parameters; ④to prediction and analyze the productivity and production of reservoir reserves for multi-stage fracturing horizontal wells. The proposed method has been applied to a three staged fracturing wells in Fuling shale gas reservoir and the utilization of the reserve in the well is analyzed. It provides technical support for the next adjustment scheme of the platform.
