Horizontal well is regarded as a mature development technique and has been widely used in all kinds reservoir developing. Many factors cause the uneven development of horizontal sections such as the differences of physical property, friction loss of horizontal section, changes of deviation angle and so forth. Therefore, wellbore flow coupled model is introduced for horizontal well reservoir to clear the influences on horizontal well’s even liquid producing profile by all kinds factors. The perforating model of horizontal section is optimized, segmented perforating to achieve even liquid producing profile of horizontal section is used. Optimization software for segmented perforating technique of horizontal well is built up based on research results, and it has achieved good result through primary application.
