The Temperature Field Distribution in Thermal Recovery and the Study on Residual Oil Distribution Laws

Article Preview

Abstract:

Western Bei II Area in Saertu Oilfield, Daqing Oilfield is the test area. It has now entered an exploitation phase of extra high water cut stage. Under the circumstance of a long time of development and complex conditions of well history in this area, it has experienced water flooding, polymer flooding and thermal recovery. Based on basic geological characteristics in the test area, this study establishes three-dimensional geological static models and conducts the fine reservoir numerical simulation of the test area. In addition, it summarizes the temperature field distribution features before and after the thermal recovery as well as causes and distribution laws of the residual oil, which provides a reliable basis for development, deployment and measures to adjust in the next step in oilfields.
