埕岛油田埕北古7潜山油藏完井工艺研究与应用

Technology Research on Chengdao Oilfield Chengbei Gu7 Hill Reservoir Completions and Its Application

埕岛油田埕北古7潜山油藏,采用气顶弹性膨胀开采油藏的衰竭式开发方式进行生产,在开发初期往往具有较高的产能、含油气井段长、生产气油比高、流体性质复杂的特点,地层喷、漏情况严重,作业施工难度大,井控安全要求高。针对埕岛潜山油藏的特点,设计、完善配套了八项完井工艺技术,为此类浅海潜山油藏的开发提供了有力技术支持。

Chengdao oilfield Chengbei Gu7 hill reservoir,using the gas cap elastic expansion of mining depletion of reservoir development mode o production,in the early stages of development tends to have higher capacity,oil-gas segment length,the production of gas oil is high the fluid nature of the complex characteristics of spray formation,leakage serious,difficult construction job,well control high security requirements. For Chengdao hill reservoir characteristics,design,improve the supporting eight completions technology,provides a powerful technical support for the development of such a shallow hill reservoir.
