| 摘 要： | 油藏启动压力梯度对油藏的储层动用有着很大的影响，启动压力梯度越大储层越难动用。从低渗透油藏流体
渗流机理上出发，采用现场早期束缚水条件下单相渗流的生产动态数据及试井解释资料，利用试井方法求得研究区的
启动压力梯度，并建立启动压力梯度与渗透率的关系。分析典型反九点井组内注水井与采油井井间的驱动压力梯度
变化特点，据此确定井间储层物性与储量动用关系。通过对比实际储层的渗透率值与所得到的储层流体启动所需渗
透率值的大小，从而判断储层内流体是否流动。该方法采用定量分析低渗透油藏井间储量动用状况，为同类油藏确定
井间剩余油分布提供了参考。

| 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. |
