埕岛油田中一区油井提液适应性及技术政策研究
|
摘要
针对埕岛油田中一区油井液量低的问题,应用油藏工程和数值模拟方法,在进行提液适应性分析的基础上开展了提液技术政策研究,结果表明以1.1~1.5的差异化注采比将区块地层压力恢复至12.0 MPa时实施分步提液,开发效果最优。前期的矿场应用取得了良好的增油效果,研究结果对埕岛油田中一区整体提液开发具有重要的指导意义。
In view of low liquid producing of oil well in Zhongyi area of Chengdao oilfield,using the methods of reservoir engineering and numerical simulation.Technical research conducted on the basis of enhanced liquid adaptability analysis.The research results show that using 1.1~1.5 differential injection-production ratio when the formation pressure level buildup to 12.0 MPa,extracts taken step by step approach, the development effect is most superior.The practice has provided an effective way for the increasing production of the reservoirs.And the result of the study has important guiding significance of overall liquid lifting in Zhongyi area of Chengdao oilfield.
