Optimization design of the fracturing horizontal well in low-permeability reservoir

Zongtian Li

Abstract

The morphology of fracturing horizontal well fracture,and the percolation characteristics and productivity of the fracturing horizontal well are analyzed.The number,shape and conductivity of the fractures are optimized,and the effects of fracture spacing and fracture position on the productivity of the fractured horizontal well are studied.The productivity prediction model of the fractured horizontal well in which the interference among the fractures is considered is established.The advantages and the disadvantages of the horizontal well fracturing technology at present are analyzed,which can provide reference for the optimization design of the horizontal well fracturing.
