Environment risk quantitative management method of oil gas long-distance pipeline

Abstract

The invention discloses an environment risk quantitative management method of an oil gas long-distance pipeline and belongs to the technical field of environment protection. Related data of technology design parameters of a pipeline in an inspection section, pipeline directions, landforms of the periphery of an environmental sensitive area, land utilization, weather, soil, water, population distribution and development plans are collected, an indicator system is established in the aspects of pipeline corrosion, third-party damage, misoperation and operating parameters to represent the possibility of environment accidents, and evaluation criteria and corresponding weights of indicators are established; environmental sensitivity grading is conducted on environment sensitive points, and environmental sensitivity assessment results serve as 1-2 weights; the leaking quantity levels are evaluated according to flow, and the weight is determined; corresponding indicators are selected according to scattering degrees after accidents occur, ecosystem types, ecological environment sensitivity and the like to reflect the environmental hazard consequences of the accidents, a pipeline environmental risk assessment indicator system is established, and the evaluation criteria and the corresponding weights of the indicators are established.

Description

technical field [0001] The invention relates to a method for quantitatively managing environmental risks of long-distance oil and gas pipelines, and belongs to the technical field of environmental protection. Background technique [0002] Existing studies mostly focus on the types, causes, and probability analysis of pipeline accidents, while in the evaluation of accident consequences, most of them focus on the consequences of life and property safety, and there are few studies on the consequences of environmental hazards: such as national The "Technical Guidelines for Environmental Risk Assessment of Construction Projects" (HJ / T169-2004) promulgated by the State Environmental Protection Administration recommends qualitative methods including analogy, weighting, and factor diagrams; quantitative methods include probability, index, event tree analysis, and fault analysis. tree analysis, etc. At present, commonly used methods include failure mode, impact and evaluation analys...
