Research on the Development Change Law of Block A after Fine Potential Excavation

No.5 Production Plant of Daqing Oil Field, Heilongjiang Province, Daqing, China

Abstract

After the comprehensive utilization of well pattern and fine potential tapping based on subdivision water injection in block A, remarkable results have been achieved in water cut control and decline control. With the continuous deepening of development degree, new characteristics have emerged in water drive development, and the change law of indicators has also changed greatly. Therefore, it is necessary for us to find out the change law of fine potential tapping development indicators, so as to provide a theoretical basis for the next sustainable and high-efficiency development. Through theoretical calculation and numerical simulation, this study gives the law of production decline and water cut change in different stages before, during and after fine potential tapping; The laws of water cut and production decline in different stages are evaluated and predicted. It provides a theoretical basis for the fine potential tapping, popularization and application of other blocks.
