Method Study Of Well Net Encrypt Adjustment For Sheng-ping 132 Block

The text particular gathers and sorts out a vast amount of seismic explanatory data and logging data of sheng-ping!32, and develop the study of meticulous geologic of Putouhua-oil layer. According to the character of the reservoir, each small layer is subdivided to five species flowing cell on plane, which supply abundance seismic data in the interest of the block oil field developing, In the basis of it, interpolation method of well point parameter is applied. The initial fields of efficiency thickness and permeability are formed, and then distributing characteristic of flow cell plane is referenced. To above parameter is effective amended with phase strip control method. Finally geologic model which is adapted to numerical simulation is set up, in the field historical fitting technique is carried through with the model. When fitting reserve, layer pressure, water cut of single well, whole water cut, and so on are met demand of precision, the numerical simulation study of different encrypt adjustment chance and adjustment project of encrypt well pattern is developed in sheng-ping132. In the instance of different encrypt adjustment, the change of development index and the distributing change of remaining oil are analyze and forecasted, and in the condition of kinds of encrypt adjustment, give the graph of data of measure of water flooding, production, water cut, recovery efficiency with development time. Economy assessment is combined, the static pressure method and the performance method are respectively applied to calculate economy effect of the block in the condition of different encrypt adjustment, and give reasonable encrypt adjustment chance and reasonable method of encrypt well pattern.At the same time, the result of numerical model of zhu-3 test block is combined, the relation of the final recovery efficiency and well pattern density is fitted Putouhua oul layer in Shengping oil field, probability and statistics and optimization control theory is applied to educe the relation expression of recovery and well pattern density in the condition of different water injection way. Economy assessment is combined, the reasonable well pattern density of Putouhua oil layer in Shengping oil field is given, which provides theory base for encrypt adjustment of other block in the oil field.
