Abstract

Abstract:

The design of shale gas well spacing is the key to the technical policy of gas field development, which is related to the maximum utilization of resources. Well spacing design is closely related to geological characteristics and fracturing technology. The well spacing of Weirong Shale Gas Field designed at the initial development stage is 400 m. With the transformation of the fracturing technology of the main body of productivity construction from “controlling the fracture propagation and making longer hydraulic fractures” to “intensive perforating”, microseismic monitoring, fracturing simulation and dynamic analysis all reflect that the reserves between production and construction wells are still not fully utilized, and the existing well spacing needs to be further optimized. In order to further improve the reserve production and recovery degree of the gas field, and realize the beneficial development of gas reservoirs, the integrated technical method of geological modeling and numerical simulation is adopted to carry out the studies on single well numerical simulation with different fracturing technology. It is clear that the difference in the production status of single well reserves is caused by the fracturing process. On the basis of the researches of the single wells, the numerical simulation model of well groups under “intensive perforating” technology is established, and the development well spacing is optimized by combining technical and economic indexes. The study shows that under the current technological and economic conditions, it is recommended that the optimal well spacing in Weirong Gas Field could be adjusted from 400 m to 300 m, and the recovery degree can be increased from 22 % to 28 % at the end of 20 years.

Key words: fracturing technology, well spacing optimization, numerical simulation, Weirong Shale Gas Field, geology-engineering integration
