Abstract

The invention discloses an oil and gas field dynamic analysis method. A next step development scheme is obtained firstly through block internal experience analysis, then the scheme is subjected to simulation analysis in combination with theoretical analysis and a mathematic model, and if an analysis result of the mathematic model is as same as or similar to a theoretically derived result, the scheme is adopted to perform adjustment; or otherwise, an analogy analysis method is adopted, blocks with same or similar properties are found out, and analogy analysis is performed to obtain a final adjustment scheme. Multiple dynamic analysis methods are adopted for mutual complementation and mutual verification, so that the problem of single oil and gas field dynamic analysis mode in the prior artis solved and the purpose of performing oil and gas field dynamic analysis in a mutual verification manner through 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 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...
