摘要
确定混相压力是混相驱的一项重要工作,核心问题是最小混相压力的确定,它是确定原油与排驱气体是否能达到完全混相的一个非常重要的参数。最小混相压力的确定方法很多,文章综合分析了实验测定和理论计算的几种常用方法,并进行了相应评价,给出了各种方法的优缺点和通用性,最终得出了确定最小混相压力的较好的几种方法,为油田注烃混相驱实践提供借鉴。
Hydrocarbon injection miscible flooding is one of important EOR methods. Meanwhile core content of hydrocarbon injection miscible flooding is minimum miscibility pressure (MMP) definition. MMP is a very important parameter to determine whether or not miscible between oil and injection gas, and has important guiding significance for the design of miscible flooding and miscible prediction.Now there are many definition methods of MMP. The paper had synthetically analyzed some experimental determination and theoretical calculation methods, obtained some good definition methods of MMP and provided reference for field practice of hydrocarbon injection miscible flooding.
