A Method for Optimizing the Parameters of Tong’s Plate in Low Permeability Oilfield

The water content curve chart with unified parameters has poor adaptability to oil fields and various blocks, this article optimizes the water content curve parameters of different blocks in a oilfield to form water content curve charts for each block, quickly and accurately judging the development situation of the block, and pointing out the direction for the next development adjustment of the oilfield. A oilfield belongs to a low-permeability oilfield, with some blocks developing fractures and being in the stage of medium to high water cut. Currently, the main method used is to predict the oil recovery rate using the well adapted decline method. By predicting the recovery rate of each small block and optimizing the water drive constant in the water cut curve, a water cut curve chart with good adaptability to each block is ultimately obtained. The water content curve obtained by this method can quickly, conveniently, and accurately determine the development situation of different blocks, and preliminarily predict the recovery rate of each small block.
