摘　　要：利用油田实际矿场资料,分析不同完井方式的生产井开采效果,对比其初期产能、表皮、出砂量、油井寿命及后期对稳油提液的影响,并分析油井日常管理对防砂效果的影响。对比发现裸眼筛管井的筛网尺寸直接影响油井产量和提频,裸眼优质筛管与压裂砾石充填完井均可充分释放产能,合理工作制度及油井状态稳定更有利于延长防砂井寿命,压裂砾石充填是适应油田特征及开发策略的一种最佳完井方式.Based on the oilfield actual data,this paper analyzes the production performance of different completion methods,compares the influence of initial productivity,skin,sand production,well life and later oil stabilizing and liquid increasing,and analyzes the influence of producer daily management on sand control effect.The results show that the screen size of open hole producer directly affects the production and frequency increasing,the open hole completion with high quality screen and Frac-pack completion can fully release the productivity.Reasonable working system and stable producer state are more conducive to extending the lifetime of wells.Frac-pack completion is the best method to adapt to oilfield characteristics and development strategy.
