针对压力测试法用压深关系图确定稠油油藏油水界面误差较大的问题,基于压力测试法相同原理,提出了一种确定油水界面的新方法——剩余压力法。蓬莱19-3油田应用结果表明,利用剩余压力法可以简单、直观地确定出较为准确的油水界面。
Aiming at the problem of large error of oil-water interface in heavy oil reservoir, a new method to determine oil-water interface-residual pressure method-is put forward based on the same principle of pressure test. Penglai 19-3 oilfield application results show that the use of residual pressure method can be simple and intuitive to determine a more accurate oil-water interface.
