Reservoir Parameter Forecast In The Plane And Mop In The Space

Carrieing on the science effective forecast to the reservoir parameter, thus instruction exploration development, always is the petroleum geology hot spot and the difficulty. At first, the people use the traditional mathematical statistic method,But this cardinal number study method does not consider the reservoir parameter the space continuity and the relevance,So it does not have any geological significance, and it has very big limitation to the reservoir parameter forecasting. Afterwards,the people have developed the geology statistical method, It takes the regionalizing variable theory as the foundation, and fully has considered geological parameter spatial variation tendency, directive and different spot parameter mutual dependence and so on, and extracts the comparison to conform to the geological rule of geology statistical model and the method, Attributes of each kind of the changing rule for reservoir parameter, Then using this kind of rule to Mops to forecast the parameter space quite reasonably and effective. The geological statistics application has realized the cardinal number study method forecast to geology understanding and mathematics method forecasting leap. Geologic statistics appeared in the 1960s, In those forty years, variogram, kriging technique and stochastic simulation technique has become the whole theory system. Kriging geological mapping technique is one of the necessary and important parts of reservoir description. It has the function to predict reservoir properties, combine data of various variables with each other, and process data with uncertainty, has important significance to use geological, seismic and logging date comprehensively, and raises application effects and technical level of reservoir description.This paper recommend theoretical foundation , estimating course and analysis about result of kriging estimate technique in details and all-around. For improving the accuracy of reservoir characterization and predict reservoir, this paper use King estimating technique and radial basis function to predict the paramete of reservoir in DongPu, protract the isoline and Spatial distribution of equivalent face of porosity, and make slice of surface coordinates along three axis direction ,analyze the structural characteristic parameter of porosity, analyze the relevance between porosity and the structural characteristic parameters of porosity, has obtained better geological result. In order to reflect more true geological characteristics of the study area, this paper combination of basic geological characteristics of the region, based on this, point out fault analysis and fault handling methods in theory, and give the algorithm, thereby improving the accuracy of the forecast.
