| Abstract: | After the oil reservoir of Maling Oil Field is waterflooded for a long time, its pore structure is changed. Based on laboratory tests and field data, the variation of the pore structure was studied. The result of the study shows that the permeability and porosity of the reservoir decreases by 12.96% and 0.44% separately. It is held that the causes of leading to the variation are the sensitive mineral existing in the reservoir, the heterogeneity of the pore structure and the change of the salinity of foreign fluid. |
