摘　　要：In view of the problems existing in the development of Xihu block of Shanghai Offshore Oil and Gas Company, such as wellbore effusion, rapid production decline, gas channeling and water invasion, this paper analyzes in detail three kinds of process technologies based on the principles of critical flow, gas lift drainage and artificial lift drainage from the aspects of process principle and field application, systematically analyzes the adaptability of drainage and production process, and combines the previous drainage and gas production experience. This paper focuses on the development direction of a new type of layered composite drainage and gas production. Through the comprehensive treatment of "source opening and throttling", the electric pump wellbore drainage and efficient water control of electric and hydraulic switches are realized, so as to greatly improve the drainage and production effect, greatly prolong the production cycle of gas wells, and promote the effective development of West Lake block.
