任11井潜山油藏改建地下储气库关键技术研究

利用油藏改建地下储气库在国内还没有先例,利用潜山油藏改建地下储气库在国外也很少见。借鉴华北雁翎油田注气矿场试验经验,结合国外油藏改建地下储气库主要理论基础,对双重介质潜山油藏注气驱动机理、库容及损失量、建库过程控制和建库周期等进行了评价研究,解决了潜山油藏改建地下储气库的多项技术难点,初步建立了一套双重介质潜山油藏改建地下储气库评价理论体系和方法。

METHODS OF REBUILDING WELL REN-11 BURIED HILL OIL RESERVOIR AS UNDERGROUND GAS STORAGE

There is no experience on underground gas storages rebuilt by oil reservoirs in China. Especially, by buried hill oil reservoirs even in foreign countries. On the basis of theories of constructing gas storage in foreign countries. The mechanism of gas drive in dual media oil reservoir, storage capacity, loss of gas, control of forming process and construction period are studied with practice experience in gas injection in Yanlin oil field. Many technical difficulties of rebuilding well Ren-11 buried hill oil reservoir as underground gas storage are solved. A series of theories and methods are established primarily.
