鄂尔多斯盆地致密砂岩储层敏感性特征及其控制因素——以新安边地区延长组长6储层为例
Sensitivity of Tight Sandstone Reservoir in Ordos Basin and Its Controlling Factor: Taking the Chang 6 Reservoir of Yanchang Formation in Xin'anbian Area as Example
摘要
Abstract
The sensitivity of Chang 6tight sandstone reservoir of Yanchang Formation in Xin'anbian area of Ordros Basin was evaluated through laboratory water flooding experiment.It is shown that,the reservoir has weak-medium velocity sensitivity,water sensitivity,acid sensitivity and salt sensitivity,and the variation range of water sensitivity is large.The main control factor of the reservoir sensitivity characteristics is clay mineral,kaolinite controls the velocity sensitivity,ilite-smectite mixed layer and illite influence water sensitivity and salt sensitivity,and chlorite influences acid sensitivity.The analysis result of reservoir clay minerals is consistent with the analysis result of reservoir sensitivity.关键词
