- Abstract
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 patterns 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 patterns, in conjunction with numerical reservoir simulation results and actual production performance of the study area. Based on the numerical simulation, together with analysis of geologic factors and performance evaluation, a performance evaluation method for clastic reservoir architecture of littoral facies was put forward, in turn, the distribution scopes of different reservoir architecture patterns 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.
