The Study on Fracture Affecting the Performance of Horizontal Well in Low Permeability Reserviors

Gu Daihong ( China University of Geosciences, Beijing 100083, China), Tian Leng.  
In this paper, the effect on the performance of horizontal well was studied about the fracture factor. By means of experiments, this study included length of fractures, number of fractures, distance between the outmost fractures and grid of fractures. Meanwhile, The rules affecting the productivity, such as horizontal well length, distance between wells, location of wells, the relation of the laying wells manner and fractures on the reservoirs ' fluid flow were quantitatively analyzed by means of physical simulation and theoretic analyze. It researched restricting situations about geology and physical in the horizontal well developing the low permeability reservoirs, and provided the instruction for the design of factual reservoirs' developing well pattern.
