Abstract

The present invention relates to an adaptability evaluation method for crude oil storage and transportation system in oil fields and mines, specifically: establishing a basic database and a production operation database; constructing an evaluation index system composed of several evaluation indexes, and the evaluation index system is a three-layer index system; determine the weight of each evaluation index in the evaluation index system; construct the evaluation grade standard and form the comment set of fuzzy comprehensive evaluation; for the qualitative evaluation index in the three-level evaluation index, use the qualitative evaluation method to determine its relative value. m The degree of membership of each adaptability level; read the fuzzy relationship matrix to obtain the degree of membership of each secondary evaluation index to each adaptability level, and construct a corresponding fuzzy relationship matrix; read the fuzzy relationship matrix to obtain the first-level index For the degree of membership of each adaptability level, determine the final level of the adaptability level of the crude oil storage and transportation system in the mine. The invention can better characterize the fuzzy gradual change characteristics between different adaptability levels, so that the evaluation result is more in line with the objective reality.

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...
