Problems solved by technology

The main problem is that a single parameter such as water injection rate, oil production rate and water production rate is used for dynamic analysis. A single parameter cannot eliminate the influence of human factors such as ground measures on reservoir development dynamics, and transfers human factors to the reservoir system, resulting in Analysis results are distorted

Embodiment Construction

[0037] In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, the preferred embodiments are specially listed below, together with the attached figure 1 The details are as follows.

[0038] 1) This embodiment selects the monthly data of an injection-production unit with 5 oil production wells and 5 water injection wells in 1995 for dynamic system analysis, and the method of the present invention conducts development effect analysis according to the following steps.

[0039] 2) Dynamic data processing, calculating comprehensive parameters according to the following formula:

[0040] Formula 1

[0041] Formula 2

[0042] Among them: Q o is the monthly oil production, Q w is the monthly water production, DYM is the dynamic liquid level of the production well, Q o ’ and Q w ’ is the comprehensive parameter after dynamic liquid level correction.

[0043] According to Formula 1 and Formula 2, the mo...

Abstract

The present invention provides a dynamic system analysis method for water injection development in an oil field, and the overall plan includes: 1) selecting an injection-production well of an injection-production development system as the analysis object; 2) processing dynamic data to calculate comprehensive parameters; Water volume correlation analysis, calculation of water drive oil coefficient and water drive water coefficient; 4) Draw water drive map; analyze water drive effect, and propose adjustment measures. When the method of the present invention uses the development dynamic data to carry out system analysis, at first the parameter of dynamic liquid level is introduced to process the oil production and water production, that is, to divide the oil production and water production by the dynamic liquid level to generate a new parameter, and then apply this Correlation analysis was carried out on comprehensive parameters and water injection volume, and finally the water flooding effect was analyzed, and adjustment measures were put forward.

Description

technical field [0001] The invention belongs to the field of dynamic analysis of oil field water injection development systems, in particular to a dynamic system analysis method for oil field water injection development. Background technique [0002] Conventional reservoir development dynamic analysis methods include material balance analysis method, displacement curve method, decline curve method, numerical simulation method, etc., but these methods need to meet certain conditions when they are applied, and these methods are based on core analysis, Formation parameters recorded in a few wells by means of well logging, well testing and pressure measurement are obviously insufficient to describe the state of the entire reservoir. [0003] The system analysis method is to reflect the dynamic characteristics of water flooding in the system by using the change law of the correlation relationship between the production characteristic parameters of all oil and water wells in the r...
