Abstract
As the oilfield development enters a high water-bearing stage, the water content of the main oil layer gradually increases, the inefficient and ineffective circulation is serious, and the remaining oil distribution is scattered. It is difficult to select the well and reservoir. Through comprehensive development of high-density 3D seismic work, the study area further elaborates the sedimentary microfacies of the reservoir, making the development of the reservoir and the connectivity between the oil and water wells clearer. At the same time, applying the well-seismic combination technology to the fault Understanding, further clarifying the relationship between injection and production, the understanding of the underground situation is becoming more and more clear. Based on the comparison and application of the fine geological research results in the study area, this paper expounds the role of fine geological research results in the remaining oil potential tapping in the extra high water cut period.
