Research on Residual Oil Distribution Regular of Steam Flooding after Polymer Flooding
Abstract:
The study on distribution laws of remaining oil in high water cut stage is the difficulty of oil field development in the mid-to late period. Aiming at the long development time of Western Bei 2 area of Saertu oilfield in Daqing Oilfield and its complicated well history conditions undergone water flooding, polymer flooding and steam flooding, the 3D geological static model has been established in this test area based on the study on its structure characteristics and sedimentary features. By applying the method of fine reservoir numerical simulation, the paper completes the numerical simulation of remaining oil in the test area and summarizes types of remaining oil as well as their distribution laws in the test area, which provides a reliable basis for the further deployment and adjustment measures in the oilfield.
