Abstract

The invention discloses an oil-gas field dynamic analysis method. According to the method, a next development scheme is obtained first through a block internal empirical analysis method; simulation analysis is performed on the scheme in combination with theoretical analysis and a mathematical model; if the analysis result of the mathematical model is identical or approximate to the theory derivedresult, the scheme is adopted for adjustment; and otherwise, an analogy analysis method is adopted to find blocks with identical or approximate properties, analogy analysis is performed, and a final adjustment scheme is obtained. Multiple dynamic analysis methods are adopted for mutual remedy and verification, the problem that in the prior art, a single oil-gas field dynamic analysis mode is available is solved, and the purpose of performing oil-gas field dynamic analysis through mutual verification of multiple methods is achieved.

Description

technical field [0001] The invention relates to the field of oil and gas development, in particular to a dynamic analysis method of oil and gas fields. Background technique [0002] Dynamic analysis means that in the process of oil and gas field development, on the basis of a large number of reliable data, multi-disciplinary knowledge and technology are used to comprehensively analyze the dynamic change laws of oil and gas reservoirs that have been put into development, and to find the relationship between various dynamic and static parameters. The overall planning and adjustment measures of oilfield development, and the correction plan according to the changing characteristics of dynamic parameters, make the reservoir achieve higher ultimate recovery factor and higher development level, and obtain better economic benefits. Development dynamic analysis runs through oilfield development, and it mainly has the following functions: (1) Establishing the geological basis for oilf...
