Abstract: Taking the littoral-facies clastic reservoir of Donghe sandstone in HD4 oil field, Tarim Basin, NW China as an example, this paper analyzes the effect of different reservoir architecture pattern on oil well production performance. There are three types of reservoir architecture pattems in the target layers of the study area, parallel, groove and oblique. The dynamic response characteristics of different reservoir architecture patterns were discussed by establishing the conceptual model of different reservoir architecture patterms, in conjunction with numerical reservoir simulation results and actual production performance of the study area, Based on the numerical eooeeaaeoeneaoae eoanseeanooe architecture of littoral facies was put forward, in turn, the distribution scopes of different reservoir architecture patterms in the study area were identified by this method. The research results show that the parallel reservoir architecture only affects oil well production in vertical direction, the oblique reservoir architecture has the strongest effect on oil well production performance, reflected in both vertical and lateral direction, the effect of groove reservoir architecture on oil well production is mainly in vertical direction, relatively weak in
lateral direction, Different adjustment measures should be adopted for the distribution areas of different reservoir architecture patterns Key words: reservoir architecture; performance response characteristics; reservoir numerical simulation; littoral facies; interlayer
0引言
储集层构型是指不同级次储集层构成单元的形态、规模、方向及其叠置关系[1-2]。通过分析油井的生产动态资料，可以了解储集层构型对地下流体运动的控制作用，为油田开发后期准确把握剩余油分布规律及制定合理开发方案提供依据，而在以往储集层构型研究中，将油井生产动态资料与储集层构型模式相结合的研究甚少。本文以哈得4油田东河砂岩滨岸相储集层为例，建立滨岸相各类储集层构型模式的概念模
