THE INITIAL POTENTIAL EVALUATION METHOD OF WATER FLOODING EFFECT IN WATER-INJECTION DEVELOPMENT RESERVOIRS

Sun Wen-tao

Abstract

To a certain sandstone reservoir, some geologic characteristic parameters before development can not only be used to describe formation and evaluate geology, also evaluate the initial potential of water flooding effect-water flooding difficulty degree, water flooding uniformity degree and water flooding recovery. The practical evaluating index is given to water flooding difficulty degree, water flooding uniformity degree and water flooding recovery respectively to water injection sandstone reservoir, and also, the corresponding index in the water injection reservoir in China is counted. The research provides reliable foundation for formulating and adjusting reservoir development plan and recovery plan.
