| 摘 要： | 油藏地层压力是一个十分重要的油藏工程参数，而塔河油田奥陶系油藏所测得的地层压力中常出现前小后大的现象，给油藏工程分析带来许多困难。笔者根据塔河油田奥陶系油藏的特点，在长期的生产实践中，通过常规油藏工程方法与油藏具体特点结合，通过原油在纵向上的重力分异现象推出油藏地层压力梯度也应随深度变化的思路，很好地解释了碳酸盐油藏地层压力前小后大问题。

| Abstract: | Reservoir formation pressure is a very important parameter in reservoir engineering study.In Tahe oil-field,the reservoir pressure obtained from its Ordovician reservoir often appears variations in late up and early down,which bring much trouble for analysis in reservoir engineering.This paper presents a detailed interpretation of them oc-curred in the carbonate reservoir,according to characteristics of the Ordovician reservoir,by applying conventional reservoir engineering method intergrated with the actual reservoir feature followed by calculated formation pressure gra-dient that should change with formation depth from crude vertical gravitational differentiation. |
