Deliverability analysis of horizontal well is the basic work of getting economic benefits, and it provides basis for horizontal well optimization, perfecting work system, production dynamic analysis and adjustment. At present, there are twomethods of deliverability calculation for horizontal well, namely analytical method and simulation method. The deliverability prediction methods for conventional horizontal well, multilateral well, fractured horizontal well and horizontal well pattern are summarized. The birth and development of deliverability analysis theory are reviewed, the new advances at home and abroad in the deliverability analysis theory and methods are introduced, the problems exists are expounded, and the development direction is pointed out, which will be helpful for improving the application of horizontal well in oilfield development.
