| 摘 要： | 利用专门建成的高压线性物理模拟装置，以吉林新立油田为原型进行了一系列ＣＯ２非混相驱模拟实验。实验内容包括ＣＯ２注入率、ＣＯ２段塞大小、交替注方式、气水比、水气同注及注ＣＯ２时机等因素对驱油效果的影响。研究结果表明：影响ＣＯ２非混相驱效果的最关键因素是ＣＯ２段塞大小和油层压力。注入率对驱替效果也有较大的影响，交替注入和气水比的影响是次要的。实验结果还表明：对新立油田而言，在较低的含油饱和度下，ＣＯ２非混相驱仍能有效地提高原油采收率。

| Abstract: | A series of modelling test on immiscible CO 2 drive for Jilin Xinli oil field was carried out with a high pressure linear model specialy set up for it. It included the effects of injecting rate of CO 2, size of CO 2 plug, alternative injection, gas water ratio, injection of gas with water opportunity of CO 2 injection and etc. on oil recovery. The conclusion is that the most important factors on efficiency of immiscible CO 2 drive are size of the CO 2 plug and pressure of the oil reservoir although effect of injection rate is rather significant and effects of alternative injection and gas water radio are less important. It also concluded that immiscible CO 2 drive is still an efficient method to rise the oil recovery in Jilin Xinli oil field with a low oil saturation. |
