Numerical Simulation Research on Optimizing Monitoring Well Point of Reservior Pressure

During the production of oilfield, it is necessary to understand the strata pressure in the recovery process, which is the so-called current formation pressure. However, how to choose the pressure monitoring well point correctly is one of the important tasks in the oilfield development. Usually the simplest method of understanding the strata pressure is actual measurement, but in order to get the actual measured strata pressure, the well should be shut for a long time, which has a great influence on production. In this paper, the average strata pressure is predicted by well test interpretation method and Pisman method, average strata pressure of volume weighted method which are both used in reservoir numerical simulation. The actual pressure distribution of the oilfield in the east of Xing-1~2 district is calculated using the above three methods. After contrasting and analyzing the received results from the three methods, the well point for monitoring the reservoir pressure is optimized through comprehensive evaluation.
