Great challenges exist in the development of tight oil reservoirs.In order to examine the influences of geological characteristics,the orientation of horizontal wells and fracture patterns on the horizontal well production,reservoir simulation models for the fractured horizontal well were built to investigate these influences.The influence index was used to quantify the effects of these geological parameters.It is indicated that,the conductivity of natural fractures is the crucial factor to the initial productivity,and the matrix porosity is the most important factor to the decline rate.During the early period,the conductivity of natural fractures plays an important role,so does the matrix porosity during the late period.The orientation of horizontal wells should be coordinated with the orientations of natural fractures and hydraulic fractures,so as to get the highest productivity.The reasonable fracture pattern should reach an improved development.
