Abstract

The invention discloses an oil and gas field dynamic analysis method. By an empirical analysis method in a block, the develop scheme including the following steps is firstly obtained; then, the scheme is subjected to simulation analysis by combining a theoretical analysis and mathematical model; if the analysis result of the mathematical model is identical or similar to the result deduced by theory, the scheme is adopted for regulation; otherwise, a block with the identical or similar property is found by an analogy analysis method; the analogy analysis is performed; a final regulation scheme is obtained. The oil and gas field dynamic analysis method has the advantages that various dynamic analysis methods are adopted for mutual compensation and mutual verification; the problem of single mode of oil and gas field dynamic analysis in the prior art is solved; the goal of oil and gas field dynamic analysis through mutual verification by various methods is realized.

Description

technical field [0001] The invention relates to the field of oil and gas development, in particular to a dynamic analysis method for oil and gas fields. Background technique [0002] Dynamic analysis refers to the comprehensive analysis of the dynamic change law of the oil and gas reservoirs that have been put into development on the basis of a large number of reliable data and the use of multidisciplinary knowledge and technology in the process of oil and gas field development, to find the relationship between various dynamic and static parameters, and to propose The overall planning and adjustment measures of oilfield development, and the modification of the plan according to the changing characteristics of dynamic parameters, so that the oil reservoir can achieve a higher ultimate recovery rate and a higher development level, and achieve better economic benefits. Development dynamic analysis runs through the whole process of oilfield development, and it mainly has the fol...
