Method used for crude oil long-distance pipeline environment risk evaluation

Abstract

The invention discloses a method used for crude oil long-distance pipeline environment risk evaluation. The method comprises the following steps that: establishing the scoring table of a crude oil long-distance pipeline failure possibility, identifying main environment risk factors which can cause crude oil long-distance pipeline failure, making a qualitative and quantitative definition on each risk factor, endowing a corresponding score, and according to the synthesis score situation of each factor, dividing the pipeline failure into high, middle and low levels; establishing environmental consequence level division, and according to the level of sensitivity of the surrounding environmental receptor of the crude oil long-distance pipeline, dividing the environmental consequence which may be caused by pipeline leakage into three levels of being severe, more severe and slight; and establishing a crude oil long-distance pipeline environment risk evaluation matrix, and dividing the pipeline environment risk level into three levels, including a low environment risk level, a medium environment risk level and a high environment risk level. By use of the method, the environment safety level of the long-distance pipeline is comprehensively evaluated, an enterprise can be guided to carry out crude oil long-distance pipeline environment risk evaluation work, and an evaluation result is more scientific and comprehensive.

Description

technical field [0001] The invention relates to the technical field of environmental risk assessment in the petrochemical industry, in particular to a method for environmental risk assessment of long-distance crude oil pipelines. Background technique [0002] With the rapid development of my country's economy, the demand for energy has experienced a blowout growth. Due to the large differences in economic development among provinces in my country, energy distribution and demand are not balanced, and there is an objective reality of long-distance energy transmission. Long-distance pipelines are favored by energy and chemical companies because of their safety, economy, and environmental protection (statistical data show that the accident probability of long-distance pipeline transportation is 0.004%, which is far lower than the probability of accidents in railway and ship transportation of 0.3%). A large domestic petrochemical company has more than 30,000 petrochemical pipelin...
