低渗透油藏井间储量动用状况分析新方法
A New Method of Analysis of Low Permeability Reservoir Interwell Reserves Producing Status
摘要
Abstract
The existence of start-up pressure gradient of reservoir has a great impact on the reservoir producing extent,the bigger the start-up pressure gradient,the poor the the reservoir producing extent. Based on the mechanism of fluid flow from the low permeability reservoir,the relationship between the start-up pressure gradient and permeability relationship of the study area were established by the in-situ early bound water production performance of single-phase data and well test material and well test method. we also analyze a typical well group pressure driven between the injection wells and production wells gradient features. By comparing values of reservoir permeability and reservoir fluid permeability values corresponding to the size,we determine whether the fluid within the reservoir may flow. This quantitative analysis of low permeability reservoir interwell reserves producing condition provides the reference for determining interwell residual oil distribution provides of similar reservoir.关键词
