Problems solved by technology

Traditional risk assessment techniques are performed under static conditions, but when operations or operations change, risks change, which makes traditional analysis methods flawed
In addition, traditional risk assessment techniques utilize generic event failure data, which makes them non-specific and also introduces uncertainty to the results, these limitations lead to the development of dynamic risk assessment methods

Abstract

The invention discloses a blowout accident risk analysis method, and particularly relates to the field of energy exploitation, and the method comprises the following specific analysis steps: S1, analyzing main cause of well kick-blowout accidents and influence factors of the well kick- blowout accidents; s2, establishing well kick- blowout accident tree; s3, converting the accident tree into a Bayesian network model by using GeNIe; s4, performing quantitative analysis on the Bayesian network model; s5, finding out a key cause factor; and S6, proposing a measure for controlling the key cause factor. According to the invention, accident causes are analyzed; the analyzed cause of the blowout accident is compiled; a reasonable blowout out-of-control accident tree and a blowout out-of-control Bayesian network model are obtained, the blowout out-of-control Bayesian network model is subjected to quantitative analysis and three importance analysis, key cause factors causing blowout accidents are found out, and a key role is played in controlling the blowout accidents.

Description

technical field [0001] The invention relates to the technical field of energy exploitation, and more specifically, the invention relates to a risk analysis method for a blowout accident. Background technique [0002] The energy industry is the leading industry of modern industry. As far as the world's energy consumption is concerned, oil and natural gas occupy the first place. With the continuous development of the modern industrialization process, especially for developing countries like my country, the demand for oil and gas will increase. However, due to the various properties of oil and gas, there are various risk factors in the exploitation of oil and gas resources, which will lead to accidents with serious consequences such as well kick or even blowout. [0003] Blowout accidents refer to the casualties of operators, environmental pollution, waste of oil and gas resources, and damage to drilling equipment caused by formation fluids ejected from the ground through the ...
