Research On Complex Fault Zone Wells Potentialof Block C6

In order to improve the residual oil of digging, people are constantly exploring new methods, but also because the continuous decrease of oil reserves people begin to view will drop it into the crude oil storage turned out to be ignored by people. The fault of the residual oil now is regarded as the dominant position of our oil field development. Because of many faults within the fault block oil field is development, size and shape also has difference, increases the residual oil exploitation difficulty of faults. So the study of complex fault zone well spacing is very important. The purpose of the study is to improve the efficiency of production, so in this paper, through a large number of C6 practical field research and theoretical research, to improve oil recovery encryption well water flooding development in computing scheme of the six sets of indicators, made clear in order to solve the current block to add the condition of the harvested, deal with DuanCengChu layout reasonable measures to improve the development effect of high Angle Wells. Do to well pattern adaptability evaluation, new wells can be encrypted.Combined with the actual condition of C6 block, the block to make use of the Eclipse and Petrel software numerical simulation, the results show that the real reservoir geological reserves of 967.35559×104t, model of geological reserves of 968.3556×104t, the relative error is 0.1%. Numerical simulation calculation of cumulative oil production and development data of relative error is 1.44%, the relative error simulation integrated moisture content of 0.29%.Area of C6 each layer fault analysis the configuration of the remaining oil saturation of edge, the results show that the block is still of remaining oil in the formation, the main distribution EⅠ14,EⅡ52,EⅢ32,EⅢ33,EⅢ41,EⅢ43,EⅢ52 and EⅢ53satisfy geological conditions. The form of analysis it is concluded that there are five types of remaining oil.In order to extract fault around the remaining oil, 6 kinds of development plan is designed. Including vertical Wells all encryption, vertical Wells gradually reduce the combination of high Angle Wells increasing encryption, the results show that the vertical Wells and the optimal scheme of combining high Angle well, and the optimal proportion.
