Abstract:

This paper considered the effect of formation damage and well completion methods and well completion parameters on the productivity of horizontal wells, and studied the mathematical models for the productivity prediction of the horizontal wells with open hole series of completion methods such as real open hole, slotted liner, wire wrapped screen, open hole down hole gravel pack, open hole prepacked gravel liner, perforated liner with open hole packer, perforated liner with open hole packer and external casing packer (ECP), and so on. Example calculations show that the mathematical models and their calculation methods are reasonable. They can be used to guide the optimum selection of well completion methods and the optimum design of well completion engineering.
