SAGD开发效果影响因素研究
|
摘要
借助数值模拟手段,从地质因素、完井方式和操作策略出发,分析了低渗带位置、低渗带渗透率、管柱结构、预热方式、注采参数等因素对SAGD开发效果的影响;其次通过正交设计方法,确定了影响SAGD开发效果的主控因素。结果表明,管柱结构对开发效果影响最大,影响程度由大到小的因素依次为管柱结构、预热时间、低渗带渗透率大小、预热方式、SAGD阶段最大排液量、低渗带位置、SAGD阶段最大注汽量。
In this paper,simulation method has been used to analyze the effect of geological factors,well completion method and operation strategy on SAGD,including the location and value of low permeability zone,string structure,start-up method,inject-production parameters. Then orthogonal design method has been used to define the main controlling factors on SAGD. The results show that,string structure is the main influencing factor on SAGD. The order of influencing factors is string structure,pre-heated time,permeability of low permeability zone,start-up method,maximum liquid producing rate,permeability distribution,maximum steam injecting rate.
