Embodiment Construction
[0041] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.
[0042] Such as figure 1 as shown, figure 1 It is a flow chart of the method for simulating reservoir properties by using multi-directional variogram analysis in the present invention.
[0043] In step 101, sedimentary microfacies are divided according to regional sedimentary characteristics. Sedimentary microfacies division of non-cored wells is a repeated step-by-step iterative and finally determined multi-cycle process, such as figure 2 as shown, figure 2 It is a flowchart of sedimentary microfacies division in a specific embodiment of the present invention. Using this process, the division of sedimentary microfacies in non-coring wells can be realized. In this process, the method of Bayesian discriminant analysis is used to quantitative...
