Economic evaluation simulation comparison method based on tertiary oil recovery projects in different periods

Abstract

The invention belongs to the technical field of oil field development, and particularly relates to an economic evaluation simulation comparison method based on tertiary oil recovery projects in different periods. The method comprises the steps of three recovery type classification, oil reservoir type classification, alignment processing of annual production data, simulation of economic evaluationparameters to evaluation time points, economic evaluation of projects of the same type, comparison and analysis of results of the projects of different types according to project classification, determination of influence factors, screening and guidance of replacement projects of the same type and the like. According to the method disclosed by the invention, the three recovery types are classifiedaccording to the three recovery medicament formulas, and the comparability of different three recovery type projects is enhanced; the oil reservoir types are classified according to the influence factors such as the material basis before polymer injection, the oil reservoir static parameters and the injection-production strength, and the comparability of different oil reservoir type projects is enhanced; by aligning production data and simulating economic evaluation parameters, the comparability of the projects in different periods is enhanced; and transverse effective comparison and evaluation of tertiary oil recovery projects in different periods are realized.

Description

technical field [0001] The invention belongs to the technical field of oilfield development, and in particular relates to an economic evaluation simulation comparison method based on tertiary oil recovery projects in different periods. Background technique [0002] Tertiary oil recovery enhanced oil recovery technology, through gas injection, chemical injection, ultrasonic stimulation, microbial injection or heat recovery to achieve enhanced oil recovery in oilfields. Shengli Oilfield carried out tertiary oil recovery laboratory tests in the 1960s, pilot tests in 1992, and industrial promotion in 1997. Through technical exploration, research tests, industrial promotion and new oil displacement system technology breakthroughs, the tertiary oil recovery technology has become the first in the Shengli Oilfield. Leading technology for sustained and stable production in mature oilfields. The tertiary oil recovery project has the characteristics of large investment and long period...

AI Technical Summary

Problems solved by technology

The tertiary oil recovery project has the characteristics of large investment and long period. At present, the tertiary oil recovery in Shengli Oilfield is facing problems such as insufficient replacement of tertiary oil recovery resources and difficulty in replacing tertiary oil recovery technology. Summarize, compare and evaluate existing tertiary oil recovery projects, and guide the implementation of similar replacement projects

Due to the different tertiary recovery types, reservoir types, and economic evaluation parameters of the tertiary oil recovery projects implemented in different periods, in the post-project evaluation process, the original economic evaluation methods have large gaps in the calculation results, and effective comparative evaluation cannot be achieved. Subsequent projects Implementation lacks guidance
