【摘要】：石油天然气物理勘探工程作为石油资源开发的先锋队,是我国油气田开发项目中重要的一步。然而油气物探工程以其风险大,作业危险性高,实施环境复杂等特点,极易引起施工作业事故发生,造成财产的损失和人员的伤亡。为了减少事故的发生,配合科学管理和决策的需要,急需针对油气物探施工作业的安全评价体系的研究和开发。本文针对于物探施工作业的安全评价问题,设计出一套基于关联挖掘方法的安全评价模型,具体的研究工作如下： (1)通过对石油物探施工作业过程中可能存在的事故隐患进行研究,基于行业相关的安全评价理论,针对物探作业过程中的危险源进行分析,划分出人不安全行为与物的不安全状态两大类安全指标,经过细分最终整理出一套符合油气物探施工特点的安全评价指标体系。 (2)针对已有的物探作业安全数据,结合物探施工作业的特点,建立以遗传算法为基础的关联挖掘方法,用数据挖掘的方式得到物探施工风险指标与事故之间的联系。 (3)将安全指标体系划分层次,根据层次分析法理论,计算得到基础安全指标对于决策目标的权重值,并利用已有的评价指标与目标间的关联规则,建立基于关联挖掘的物探施工作业的安全评价方法。 (4)基于在现场实时采集的物探施工数据,利用油气物探安全评价模块对当前施工作业安全状况进行评价和分析,安全评价的结果与事实情况基本一致。 (5)设计并实现基于关联挖掘的安全评价模型。
[Abstract]:As a vanguard of oil resource development, petroleum and natural gas physical exploration project is an important step in oil and gas field development project in China. However, because of its high risk, high operational risk and complex implementation environment, oil and gas geophysical exploration projects are prone to cause accidents in construction operations, resulting in property losses and casualties. In order to reduce the occurrence of accidents and meet the needs of scientific management and decision-making, the research and development of safety evaluation system for geophysical exploration construction is urgently needed. Aiming at the safety evaluation of geophysical exploration construction, a set of safety evaluation model based on association mining method is designed in this paper. The specific research work is as follows: 1) through the study of the potential accident hidden danger in the course of petroleum geophysical exploration construction, based on the safety evaluation theory related to the industry, the hazard sources in the process of geophysical exploration operation are analyzed. Two kinds of safety indexes of human unsafe behavior and unsafe state of objects are divided and a set of safety evaluation index system which accords with the characteristics of oil and gas geophysical exploration construction is sorted out by subdivision. 2) aiming at the existing geophysical exploration operation safety data and combining the characteristics of geophysical exploration construction, the association mining method based on genetic algorithm is established, and the relation between geophysical exploration construction risk index and accident is obtained by data mining. Thirdly, the safety index system is divided into different levels. According to the analytic hierarchy process theory, the weight value of the basic security index for the decision goal is calculated, and the association rules between the existing evaluation index and the target are used. The safety evaluation method of geophysical exploration construction operation based on association mining is established. Based on the geophysical exploration construction data collected in real time, the safety evaluation module of oil and gas geophysical exploration is used to evaluate and analyze the safety status of current construction operation. The result of safety evaluation is basically consistent with the actual situation. The security evaluation model based on association mining is designed and implemented.
