摘要
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。
For the pressure test method,a pressure-depth plot is used to determine the oil-water contact in heavy oil reservoirs,which may result in a bigger error.Therefore,a new method to determine oil-water contact,excess pressure,is proposed on the same principles as the pressure test method.An application of this new method in PL19-3 oilfield has shown that more reliable oil-water contacts in heavy oil reservoirs can be simply and visually determined.
