The Study Of Water Control And Potential Tapping In The West Of Nan-6 Block Of Sartu Oilfield

By developing millions nodes numerical simulation, an fine 3-D reservoir model was built in this paper,in order to solve the existing problems and contradictions during the ultra-high water cut period in the west of Nan-6 Block of Sartu Oilfield. Combining with the developmental character, the description of remaining oil can be quantitative by performing the fine historical matching method. Based on the quantized description, the ultra-high water cut area and the abundant area of remaining oil of the reservoir are determined, as well as the inefficient or invalid injected water circulation and remaining oil potential. The preferred comprehensive regulation of water-cut control and potential tapping is established by applying with the multidisciplinary techniques, which can improve the integral development effect of the whole block.This research results is also a good guide for the other blocks of the Sanan developing area. The multidisciplinary research method is that to combine with the results of the reservoir numerical simulation and dynamic analysis so on, which is the main direction of the fine reservoir research of Daqing Oilfield.
