Embodiment Construction

[0038] The numerical simulation dynamic analysis method of the oil and gas reservoir development unit and well group of the present invention is a dynamic analysis method of approximate numerical method, which can solve the problem of common reservoir engineering analysis method and empirical formula analysis method due to the use of average oil field data. The dynamic analysis and prediction made are often inconsistent with the actual dynamic reflection. It can also solve the problem that the dynamic analysis and prediction results made by ordinary reservoir engineering analysis methods and empirical formula analysis methods are too general, and are labor-intensive and labor-intensive with reservoir numerical simulation methods. The contradiction between resources and time, and the cost is too high.

[0039] Such as figure 1 As shown, the numerical simulation dynamic analysis method of the reservoir development unit and well group of the present invention specifically includes th...

Abstract

The invention relates to an oil and gas reservoir development unit and well group numerical simulation dynamic analysis method. The method includes the steps of analyzing the injection and production relation and the production state in a development unit, putting forward a reasonable adjustment potential tapping measure, obtaining a sweep triangle followed by an oil reservoir production degree and volume sweep efficiency relation curve from a matter balance equation, making the oil reservoir production degree and volume sweep efficiency relation curve fall into the sweep triangle when matter balance of an oil reservoir is kept, and judging the oil reservoir dynamic state from the form and tendency change of the curve. Meanwhile, in order to further learn the detailed dynamic situation between wells in the oil reservoir, the oil reservoir needs to be subdivided into subunits; a virtual boundary is drawn for a well group unit, and the problem that a non-flow boundary is troublesome to process is ingeniously solved by adjusting parameters in the dynamic analysis process. A numerical result can be given by conducting dynamic monitoring and dynamic analysis and prediction on the oil field production, and the oil reservoir dynamic situation can be simply and clearly reflected.

Description

Technical field [0001] The invention relates to the technical field of oil reservoir engineering, in particular to a numerical simulation dynamic analysis method for oil and gas reservoir development units and well groups. Background technique [0002] After the development policy of a certain oil field is formulated, how to formulate a complete development plan around this policy according to the development principles is an important issue faced by reservoir engineers. There is no doubt that the reservoir engineering method is one of the best ways to solve this problem. Different development periods of oil fields have different program requirements. Reservoir engineering methods can not only grasp the established development policy as a whole, but also can customize the development program very conveniently. However, for the preparation of mid- and late-stage adjustment plans and enhanced oil recovery plans, it is necessary to study the smaller areas inside the reservoir and b...
