摘要: 为了确定了CO2与榆树林油田原油的最小混相压力,在传统的测试方法的基础之上,提出并且完善了新的原油与CO2最小混相压力的确定方法;应用了高温高压的微观模型实验寻找原油与CO2的最小混相压力,对比进行了细管实验和长岩心注入工艺实验的研究,证明综合应用结果要比以往的更直观和准确;确定了CO2与榆树林油田原油的最小混相压力。证明了微观实验确定最小混相压力的可靠性。

Abstract:

In order to determineminimum miscibility pressure (MMP) inYushulin oil field, a newmethod was carried out and perfected basing traditional tests. The means ofmicrocosmic experimentprimarilywas used to searchMMP between oil and CO2,and in order to contrast the resultslim-tube and long core experimentation were carried on. These proved that the comprehensive
result ismore accurate and audio-visua.l As a result, MMPwas determined and at the same time the reliability of determining MMP according to microcosmic experimental resultwas verified.

Key words: CO2miscible flooding, minimum miscibility pressure, enhanced oil recovery, newmethod
