Adaptability evaluation method for crude oil storage and transportation system of oil field

Abstract

The invention relates to an adaptability evaluation method for a crude oil storage and transportation system of an oil field. The method concretely includes establishing a basic database and a production operation database; constructing an evaluation index system composed of a plurality of evaluation indexes, the evaluation index system being a three-layer index system; determining weights of different evaluation indexes in the index evaluation system; constructing an evaluation level standard and forming a remark set of fuzzy comprehensive evaluation; determining the degree of membership of qualitative evaluation indexes in the third-level evaluation indexes to m adaptability levels by adopting a qualitative evaluation method; reading a fuzzy relation matrix and obtaining the degree of membership of different second-level evaluation indexes to different adaptability levels and constructing a corresponding fuzzy relation matrix; reading the fuzzy relation matrix and obtaining the degree of membership of first-level indexes to the different adaptability levels and determining the final level of adaptability of the crude oil storage and transportation system of the oil field. According to the invention, the fuzzy gradual change characteristics among different specified adaptability levels can be well represented and evaluation results meet objective reality better.

Description

technical field [0001] The invention relates to a crude oil storage and transportation system in an oil field, in particular to an adaptability evaluation method for a crude oil storage and transportation system in an oil field. Background technique [0002] The crude oil storage and transportation system in the mine is the central key link connecting oilfield exploitation and downstream petroleum refining, and meeting the demand for oilfield crude oil exploitation, storage, measurement and export is its primary task. However, with the deepening of oilfield exploitation, crude oil production declines, which leads to a decrease in the adaptability of the crude oil storage and transportation system to oilfield production, and the safety and economy of the oil storage and transportation scheduling process of the storage and transportation system are significantly reduced. Therefore, it is necessary to clarify the adaptability of the mine crude oil storage and transportation sys...

AI Technical Summary

Problems solved by technology

Generally speaking, the crude oil storage and transportation system of a mine is composed of several large crude oil depots, oil pipelines, and a large number of auxiliary production equipment and facilities. Due to the large and complex system, it is difficult for general evaluation methods to comprehensively and objectively evaluate the adaptability of the system. Evaluation
