摘要: 混相压力是确定油藏能否采用混相驱的重要依据,测定混相压力的方法最好的是细管试验法,文中首先选用了一些最小混相压力经验关联式对此进行了预测,然后对大港油田五个区块的原油进行了混相压力测定,并分析了在不同驱替体积下的气油比、采收率、出口气组成变化。结合目前区块的油藏条件分析了采用混相驱替的可能性,筛选了适合于注二氧化碳混相驱的井,还介绍了测试装置及结果。

Abstract: The miscible pressure is a important foundation to define miscible flooding using in the reservoir . The best method of miscible pressure determination is capillacy test.The authors forecast the minimum miscible pressure by some experience formula,and the miscible pressure of oil in five sections of Dagang oilfield is determined.Then,the authors analysis gas oil ratio,recovery ratio in different flooding volume.

Key words: miscible flooding, miscible pressure, determination
