【摘要】：近几年,随着对油气资源需求及勘探开发技术的进步,对非常规油气资源的开发逐步成为了我国油气资源开发的重点领域。为了有效加强井下工具实际应用的功能可靠性及使用寿命,胜利油田采油研究院建立了针对非常规油气水平井压裂完井的井下工具模拟实验室,通过建立地面试验装置,模拟井下高温高压条件,进行全面科学地系统试验改进,设计完成能够有效适应工况的井下工具。作为胜利油田非常规油气资源开发技术的重要部分,本文针对完井工具研发的试验研究提出了安全评价及风险控制的系统方案。主要包括根据现场调研,针对试验装置设计科学可行的场地安全布置方案;在此基础上,结合FMEA风险分析理论对实验室主要设施进行危险源分析,构建实验室整体风险源评价结构体系,计算风险分级;同时开展实验室模糊安全评价,借助层次分析和风险矩阵结合定量评估实验室的安全等级;最终在量化评估数据的基础上制定全面的安全管理方案,在结合场地安全布置设计的前提下,对不同分区的硬件监控系统及软件报警系统进行了设计布置,保障试验数据及安全的实时可控性,另外结合安全防护、防爆墙及应急预案,建立实验室日常安全生产体系。在论文开展中,借助了定性与定量结合的研究思路,同时参考了GIS空间分析理论、爆炸燃烧机理和安全监测的相关理论,得到综合全面的系统研究成果;同时为胜利油田采油工艺研究院相关试验项目的开展提供了安全评价的参考依据。
[Abstract]:In recent years, with the development of oil and gas resources demand and exploration and development technology, the development of unconventional oil and gas resources has gradually become the key field of oil and gas resources development in China. In order to effectively enhance the functional reliability and service life of downhole tools in practical application, Shengli Oilfield Oil recovery Research Institute established a downhole tool simulation laboratory for fracturing and completion of unconventional horizontal oil and gas wells. This paper simulates the condition of high temperature and high pressure in the downhole, carries on the comprehensive and scientific systematic test and improvement, and designs and completes the downhole tool which can effectively adapt to the working conditions. As an important part of unconventional oil and gas resource development technology in Shengli Oilfield, this paper presents a systematic scheme of safety evaluation and risk control for well completion tool development. It mainly includes the design of scientific and feasible site safety layout scheme according to the field investigation. On this basis, combined with the FMEA risk analysis theory, the main laboratory facilities are analyzed, the overall risk source evaluation structure system is constructed, and the risk classification is calculated. At the same time, the fuzzy safety evaluation of laboratory is carried out, and the safety grade of laboratory is evaluated quantitatively by means of AHP and risk matrix. Finally, on the basis of quantitative evaluation data, a comprehensive safety management scheme is established. Under the premise of site safety layout design, the hardware monitoring system and software alarm system in different districts are designed and arranged. To ensure the real-time controllability of test data and safety, in addition to the combination of safety protection, explosion-proof wall and emergency plan, the laboratory daily safety production system is established. In the development of the thesis, with the help of qualitative and quantitative research ideas, and referring to the GIS space analysis theory, explosion combustion mechanism and safety monitoring theory, comprehensive and comprehensive research results are obtained. At the same time, it provides a reference for safety evaluation of relevant test projects in Shengli Oilfield Oil production Technology Research Institute.
