Fine Numerical Simulation Study Of Microfacies Constraints On The Second Class Reservoir At The North No.1Area Off The East And West Blocks

Fine reservoir simulation methods can we get accurate data on the geological model of the forecast calculation. Reservoir simulation applications fine reservoir description method can achieve a clear flow cell, to create a dynamic geological model, the use of heterogeneity characterization techniques, the use of reservoir stochastic simulation methods and results, microscopic percolation mechanism to achieve development period of high waterIn this paper, the North No.1area off the east and west blocks studied several aspects, including:statistical different sedimentary microfacies different position physical data, analyzed and summarized the north No.1area off the east and west blocks micro-phase boundary of the physical changes through the establishment of the No.1area off the north west east geological block model-based data preparation for the fine geological model; utilize sophisticated numerical reservoir simulation method for the North West, the East block off an area study conducted by variation of the physical properties of micro-phase boundary water flooding simulation studies; establish polymer flooding model for the numerical simulation of the fine on the basis of polymer flooding on water flooding model.Fine numerical reservoir simulation using the method of a district in the North No.1area off the east and west blocks got off the normal numerical simulation method is more accurate results. Parts of properties through statistical variation Sa Portuguese, river sand, sand sheet internal and external physical difference is obvious; larger phase boundary changes in physical properties, plus virtual wells, improve water flooding simulation single well fitting accuracy; establish an area off the North No.1area off the east and west blocks geological model achieve the required accuracy and numerical simulation studies; numerical simulation of the North East, an area off the west boundary of the block before and after correction phase model in many ways to achieve a higher level of simulation accuracy. Adopt revised geological model, a substantial increase in individual well water flooding and polymer flooding fitting accuracy.
