第一节油气藏中的静态状况 、各种压力概念」 Concept of various pressures 压力是地层能量大小的反映,知道了油气藏的压力场 就等于知道了油层中的流体流动状态。 1、原始地层压力P1 Initial formation pressure p1 油层压力指油层中部的孔隙内的流体压力。油气藏在开 发以前,一般处于平衡状态,此时油层中的流体所承受的压 力称为原始地层压力。 The reservoir pressure is the fluid pressure within the pores in the middle of oil formation. The reservoirs remain a state of relative equilibrium before development) generally, and at this point the fluid pressure is called initial formation pressure
