本研究以定向井为例,采用预先危险性分析法和事故树分析法,针对钻井过程中的钻进工程与完井工程两个过程进行安全分析。对施工过程中可能产生的危险有害因素和工程事故进行预先危险性分析,对其中存在的发生频率较高、危险性较大、造成经济损失较严重的井喷失控火灾爆炸事故进行事故树分析,并根据分析结果给出相应的安全防范措施。
Taking the directional well as an example, this study uses pre-hazard analysis and fault tree analysis to analyze the safety of the two processes of drilling engineering and completion engineering. The risk factors and construction accidents that may occur during the construction process are analyzed in advance, and the accident tree analysis is carried out on the blowout uncontrolled fire and explosion accidents with higher occurrence and greater danger and greater economic loss. According to the analysis results give the corresponding safety precautions.
