不同含水期启动生产压差变化规律探讨

油田进入开发后期，调整挖潜的重点集中在低渗爱的低含水层位，这些动用差的储层主要是由于层间干扰所致。在油田开发过程中，油藏工程师非常重视储层物性的非均质及其对油藏采收率的影响，而对层间不同含不率引起的干扰现象重视不够，笔者从理论到现场分析探讨了含水率差异引起的层间干扰问题，以指导油田高含水开发期的调整，挖掘潜力。

An approach to the variations in trigger producing pressure differences under different water-table regimes

In the later stage of development, the exploitation of an oil field should be focused on the low aquifers with medium- or low-permeability. An oil pool engineering often pays more attention to the inhomogeneity of reservoirs and its effects on pool recovercy but less attention to the intraformational interferences caused by different water contents. The differences in intraformational permeability are interpreted as the internal geological factors giving rise to the intraformational interferences. The present paper deals in detail with the differences in order to conduct the well spacing adjustment and intraformational digging.
