文中主要研究了车30井区石炭系包谷图组储层,对于该储层的岩石通过压汞实验分析,明确了该储层属于低孔隙度、低渗透率、小吼道的裂缝-孔隙双重介质储层;通过对储层地质特征分析,明确了石炭系包谷图储层岩性、颗粒成分、填隙物、结构、物性等特征;敏感性伤害分析表明:液相侵入是造成储层酸敏、水敏伤害的主要潜在因素;固相颗粒侵入造成储层孔喉堵塞是次要潜在伤害因素。
This paper put research on the reservoir of Carboniferous BAOGUTU in the che30 well field.Based on mercury penetration experiment of this reservoir,and make explicitly that it is a reservoir with low-porosity,low permeability and double porosity of gutter and small voids,it also analysesed the reservoir geologic feature and made out the feature about reservoir lithology,grain composition,matrix,structure,physical property of the reservoir of Carboniferous BAOGUTU and so on.The analysis of sensibility damage...
