摘要

摘要: 为确定特低渗透油藏在不同注水条件下的注水界限,在建立考虑微可压缩流体非稳态流动的一维水驱油相似准则模型的基础上,确定了与现场模型相对应的试验模型参数。根据室内试验结果,利用相似准则模型求出了现场不同注水条件下的注水参数之间的关系。结果表明:在注入量确定的条件下,特低渗透油藏注水开发渗透率界限随着井距的增大而增大,两者呈线性关系;在井距一定的条件下,特低渗透油藏注水开发渗透率界限随着注入量的增大而增大,两者也呈线性关系。这为特低渗透油田确定合理的井距和注入量提供了理论依据。

Abstract: To determine injection limits under different water injection conditions in an ultra-low permeability reservoir,based on the similarity theory model of one-dimensional waterflooding in consideration of the transient-state flow of a slightly compressible fluid,experimental parameters corresponding to field model were determined.According to laboratory results,similarity theory model was used to determine the relations between injection parameters under different water injection conditions.The results showed that:the waterflooding permeability boundary of ultra-low permeability reservoir increased linearly with the increase of well spacing under the conditions of given injection rate,and the waterflooding permeability boundary of ultra-low permeable reservoir increased linearly with the increase of injection rate under given well spacing.
