中北大学学位论文 中北大学学位论文 低矮型带压作业装置设计与研究 摘要 通过分析带压作业装置在国内外的研究与应用现状，针对我国油田低压、低渗、低 产的特点，并结合带压作业设备在油田生产上的具体情况，设计开发了一套稳定性和自 动化程度高，运输安装便捷，生产高效的低矮型带压作业装置。 分析了不同类型带压作业设备的优缺点，阐述了带压作业系统的组成以及工作原 理，根据我国的具体国情，确定低矮型带压作业设备为研究对象。确定了带压作业装置 举升系统、卡瓦系统、防喷系统的主要技术参数，并给出了这些部件的结构设计。根据 API Spec 16A 和 GB /T 20174 2006 的要求对低矮型带压作业进行了总体结构设计。 井口防喷系统是带压作业装置的核心部分，对带压作业设备的防喷系统做了重点的 研究设计。分析了闸板防喷器和环形防喷器的工作原理，介绍了其主要组成部分。在此 基础上对 2FZ18-35 双闸板防喷器和 FH18-35 环形防喷器的总体结构进行了设计。利用 ANSYS 软件和有限元理论对防喷器壳体进行仿真和静力学分析，得到等效应力最大值 和变形最大值及出现的位置。结果表明在 35MPa 的压力等级下壳体强度满足要求。 关键词：带压作业，防喷器，结构设计，有限元分析 The Design and Research of Low Snubbing Service Equipment Abstract Based on the analysis of snubbing devices of their research and application status at home and abroad, aiming at the features of low pressure, low permeability and low yield in domestic oil field and combining the situation of the snubbing device in oil field production, a set of low-rise snubbing device with high degree of automation and stability is designed and developed, which is convenient in transportation and installation. After analyzing the advantages and disadvantages of different types of snubbing device, introduced on the composition and working principle of the on-off flexible seal system in snubbing service. According to the specific condition in China’s oil field, this thesis will focus on the design of low-rise snubbing device. Identified the main technical parameters of the snubbing service system, fastening clips system, BOP system, and gives the structural design of these components.According to API Spec 16A and GB/T 20174 2006, the low-rise snubbing device has becarried designed integrally. Emphasized research and design is carried out on the wellhead blowout preventer equipment detail, because it is the core part of the snubbing service. The working principle of the equipment is analysed and describe is done on the main component. The overall structures of 2FZ18-35 Double Ram BOP and FH18-35 annular BOP were designed on this basis.
