Residual oil distribution and stimulation for SZ 36-1 oilfield in high water-cut stage

摘要

SZ 36-1 oilfield has entered high water cut stage, and thus research on the distribution of oil is important for tapping potential in oilfield. In this paper, the distribution of residual oil of SZ 36-1 oilfield was discussed by fine reservoir description and dynamic analysis. The saturation of residual oil at faults, "died oil" between two well, the top of positive rhythm sand body and low (no) permeability interlayer is higher than other situations. We point out that infilling adjustment wells, increasing the oil well productivity and structure adjustment of produced liquid are efficient measures to enhance oil recovery for SZ 36-1 oilfield.
