Abstract

Sulige gas field is a typical tight sandstone gas reservoir. Single well stimulation is an effective means of late fracturing. Because of the complex geological conditions in the Sulige area, there is little research on fracture parameter design of fractured horizontal wells. Based on the geological and engineering parameters of fractured horizontal wells in the block, the numerical simulation method is used to analyze the block. It is clear that the main controlling factors affecting the fracturing effect in the well area are fracture conductivity, fracture length, and fracture cluster number, and the optimal scheme to improve the single well production is proposed.
