针对低孔低渗储层束缚水饱和度高、油水同层发育、偏油同层与偏水同层识别技术不完善、射孔难度大的实际情况,以大庆西部外围某油田为例,利用依据压汞资料反演所求取的含水饱和度Sw与依据油水两相渗流实验所求取的束缚水饱和度Swi的交会图,能较好的识别偏油同层、油水同层及偏水同层,符合率达77.8%,该方法对低孔低渗储层油水同层识别及射孔方案编制工作具有一定的指导意义。
Aiming at the fact that the irreducible identification technology of the same layer in the same layer and the same layer of partial oil and the difficulty in perforation are the irreducible irreducible water in the low porosity and low permeability reservoirs, Based on the cross-plot of the calculated water saturation Sw and the irreducible water saturation Swi obtained from the oil-water two-phase seepage experiment, The same layer, with a rate of 77.8%, the method of low-porosity and low permeability reservoir identification of oil and water and perforating program preparation has some guidance.
