川西坳陷高庙子下沙溪庙组JS_3~(3-2)气藏试采情况揭示三条河道产能具有明显的差异,本文从“源”(烃源断层通道条件、气运移相态)、“相”(沉积微相、河道砂体宽度、物性条件)、位(砂体与断层配置关系、储集体与断层距离、圈闭条件、保存条件)三大方面细化比对分析,明确了影响该气藏丰度及产能差异的主要因素为烃源断层通道条件及圈闭条件差异,次要因素为物性差异。
The trial production of JS_3 ~ (3-2) gas reservoirs in Shaximiao Formation of Gaomiaozi in the western Sichuan Depression revealed that there were significant differences in productivity between the three rivers. From “source” (hydrocarbon source channel condition, ), Phase (sedimentary microfacies, channel sand body width, physical conditions), bit (sand body and fault configuration relationship, reservoir and fault distance, trapping conditions, preservation conditions) than the three aspects of refinement The main factors affecting the abundance and capacity difference of the gas reservoir are the channel conditions and the trap conditions of the hydrocarbon source faults, and the secondary factors are the physical differences.
