【摘要】 针对油田当前常用连续管作业机的运行安全性、经济性及管理问题，开展了连续管作业机的安全评价方法研究，特别是长期在役的超深井连续管作业机运行安全问题，建立了连续管作业机系统的完整性评价方法。根据连续管作业机各部件失效频次、失效类型及部件的重要性不同，如注入头、连续管及滚筒结构等承受不同载荷特性和不同失效方式，建立不同的评价方法，在各部件安全性评价结果的基础上，依据各部件自身的安全运行重要性与经济价值重要性，通过赋予部件一定的权重系数建立连续管作业机系统完整性评价方法，评价结果可为连续管持续使用、降级使用、维修使用及报废再制造提供科学依据。部件权重计算是通过有经验的技术专家、安全管理专家及连续管设计专家评分，建立重要性权重，综合考虑安全性、经济性等指标，应用层次分析法建立各部件的权重系数。在此研究基础上，提出了连续管作业机系统安全运行的完整性评价方法，并开发连续管安全评价软件。以JJY5384TLG型连续管作业机整体安全性评价为例，整体安全性评价结果为86.9，部件和整体的评价结果给出了连续管作业机系统的完整性评价结论及建议措施，评价结果可为油田管理者对连续管作业安全运行的完整性评价提供科学依据。更多还原

【Abstract】 For the safety operation, operating economy, and management issues of commonly used coiled tubing operation machines in oil and gas fields, the research on the safety assessment of coiled tubing operation machines was carried out, especially for the o peration safety issues of long-term in-service coiled tubing operation machines for ultra-deep wells. An integrity assessment method for coiled tubing operation machine systems was established. Based on the failure frequency, failure types, and importance of each component of the coiled tubing operation machine, such as the injection head, continuous pipe, and drum structure, which bear different load characteristics and undergo different failure modes, different assessment methods were established. According to the safety assessment results of each component, the importance of the safe operation of each component, and the economic value of the components, a method for evaluating the integrity of the coiled tubing operation machine system was established by assigning certain weight coefficients to the components. The assessment results could provide a scientific basis for the continuous use, reduced use,maintenance use, and scrapping use of the coiled tubing. The calculation of component weights was achieved by having experienced technical experts, safety management experts, and coiled tubing design experts score and establish the weights based on their assessment of importance. Comprehensive consideration was given to indicators such as safety and economy, and the analytic hierarchy process was applied to determine the weight coefficients for each component. Based on this research, an integrity assessment method for the safe operation of coiled tubing operation machines was proposed, and then the coiled tubing safety assessment software was developed. Through the overall safety assessment of the JJY5384 TLG coiled tubing operation machine, the overall safety assessment result was 86.9. The assessment results of each component and the overall assessment results yielded the integrity assessment results and recommended measures for the coiled tubing operation machine system, providing a scientific basis for the managers of oil and gas fields to evaluate the integrity of the safe operation of the coiled tubing operations.更多还原
