鸭儿峡油田白垩系储层敏感性试验研究

Experimental Study on Reservoir Sensitivity in Cretaceous Ya'erxia Oilfield

鸭儿峡油田作业区属玉门油田的一个区块,平均渗透率在10m D,为低渗油藏,为研究该储层的敏感性,本文通过油层取心按行业标准研究了白垩系油藏储层的流速敏感性、水敏性、盐敏性、碱敏性和酸敏性,并评价各自的损害程度,为鸭儿峡油田合理的注水开发提供理论依据,提高油田的经济开发效益。

Ya’erxia oilfield belongs to a block of Yumen oilfield,its average permesbility is 10 m D, so it is low permeability reservoir. In this paper, in order to research the reservoir sensitivity, through reservoir coring, velocity sensitivity, water sensitivity, salt sensitivity, alkali sensitivity and acid sensitivity of the cretaceous reservoir were studied according to the industry standard, and their damage degrees were evaluated, which could provide the theory basis for Ya’erxia oilfield’s reasonable water injection development.
