The application of Stochastic Modeling Technology in reservoir description of block h7-10 in liaohe oilfield

Stochastic Modeling Technology can effectively depict reservoir heterogeneity, and quantitatively research uncertainty of reservoir evaluation. Stochastic Modeling Technology has become an important part of reservoir description and formation expression, effectively promote reservoir description technology to quantification direction's development. In view of strong reservoir heterogeneity in manufacturing district, stochastic modeling is carried out for reservoir by establishing structural model, facies model and 3D model of reservoir parameters. This paper use a method of combination of facies control method and co-Gaussian simulation to run reservoir parameters Simulation, make full use of micro-facies control function for reservoir parameter, reduced uncertainty of inter-well simulation, raise accuracy of modeling, satisfactorily solve consistency problem between simulation parameters, reflect correlation relationship between these parameters. In the 3D geological model of reservoir, the paper use slice method on vertical, base on which each 4m depth of single well top depth on vertical is a slice to a model, to original oil-water interface, totally divide to 10 slices. The following 40M under oil-water interface is divided into 10 slices. Internal Structure of out sized thick oil layer is effectively analyzed, a reliable basis is provided to accurate evaluation of oil and gas reservoir's nature, flooded laws and digging remaining oil potential.
