Oil and gas pipeline station yard design method based on safety life cycle

Abstract

The invention discloses an oil and gas pipeline station yard design method based on a safety life cycle. The method comprises the following steps: 1, collecting basic data required by project design according to a project type; 2, designing a technological process, an auxiliary process and an auxiliary facility of the oil and gas conveying pipeline station yard; 3, carrying out risk analysis and risk assessment work on the oil and gas pipeline station yard; 4, analyzing the analysis work of the corresponding protective layer and proposing a corresponding improvement scheme according to the evaluation result and the risk points proposed in the operation process; 5, compiling a design technology requirement file and a purchase file of the oil and gas pipeline station according to the requirements of the oil and gas pipeline station process and auxiliary facilities; 6, performing simulation calculation by using a Markov method, and forming an SIL verification report of the oil and gas pipeline station according to a verification calculation result; and 7, compiling a design file of the whole oil and gas pipeline station yard, and bringing safety requirements and an improvement schemegiven by SIL verification into repair and maintenance requirements.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline station design, in particular to a design method for oil and gas pipeline stations based on a safety life cycle. Background technique [0002] Oil and gas pipelines have made considerable development and continuous progress in the direction of large diameter, high pressure, and networking. As of the end of 2017, the total mileage of long-distance oil and gas pipelines in China was approximately 133,100 kilometers. While the backbone pipeline network is becoming more and more perfect, the early construction of oil and gas pipelines has gradually entered a high incidence of equipment failure; at the same time, in order to meet the requirements of resource regulation and pipeline network operation optimization, some existing stations have implemented upgrading and reconstruction projects. The need for harmonious development of functional complexity and pipeline operation safety is becomi...

Problems solved by technology

[0003] At present, in the whole life cycle of oil and gas pipeline stations, it is impossible to plan and design the project construction period, pipeline operation period and pipeline maintenance period in a unified way, which will always cause mutual influence or conflict between the construction or maintenance work in each period , unable to ensure the safe and stable operation of oil and gas pipeline stations in their entire life cycle
