井口拉压扭装置论文：井口拉压扭装置结构及液压设计【中文摘要】中国的石油资源形势严峻,目前新增加的石油探明储量已经满足不了原油生产的要求。中国的原油产量稳中有增,但是与经济发展的速度相比还存在着一定的差距,对国民经济的长远发展来讲十分不利。我国的石油消费增长迅速,供需矛盾日益突出,石油对外依存度日益提高,已经接近警戒线“50%”,国家石油安全形势令人担扰。中国要保证经济稳步发展的同时节约使用石油、控制石油消费过快增长、提高老油田的石油采收率、深度二次开发老油田,争取稳产增产增效。随着油气田开采的发展,国内外各大油田加大了对井下工具的研究力度。井口拉压扭装置是一种配套实验装置,是配合综合试验井井口和油浸实验装置试验罐口以及井下工具完成封隔器的机械坐封、解封、下井管柱的举升和拆装等典型井口操作任务。本论文介绍了井口拉压扭装置的国内外发展概况,明确了装置的研究内容,确定了装置各部分连接的总体方案,详述了装置的工作原理,分析了装置的机械部分和液压部分,并且利用CAD软件完成了装置关键机构的二维结构设计,同时还对重要零部件进行强度分析和参数计算。目前,井口拉压扭装置已经进行了为期三个月的实地试验,试验证明装置的性能可靠、运转良好,能够满足油田井下工具的试验要求。【英文摘要】Chinas oil resources are scarce, and the present oil has been found cant satisfy the crude oil production requirement. Chinas crude oil output has increased steady, but there is still some gap comparing with the rate of economic growth, so its unfavorable to the long-term national enecnomic development. Consumption of oil is growing rapidly in China, the contradiction between supplyying and demand has become increasing prominently, and the dependence on foreign oil is increasing day by day, and has already been around 50% of the cordon, the situation is more worrying. China has to ensure economic develop steadily, save the use of oil at the same time, and control over-rapid growth of oil consumption, aslo improve the old oil fields of oil recovery, strive for yield increase efficiency.Along with the development of exploitation, many big oilfields have strengthened the study on dynamics of the down hole tools both at home and abroad. The tension and compression twist device is a supporting experiment device that is with comprehensive test wellhead and oil-immersed experiment device test openings and down hole tool complete packer of mechanical seal, sit and lower well un-ban string of lifting and disassembling and other typical wellhead operating tasks.This paper completes the design of wellhead tension, compression twist device structure and hydraulic system. This paper introduces the tension compression of the domestic and foreign development profile twisted device, and makes the device research content clear. The machinery parts and hydraulic parts are detailed analyzed and identified the overall plan of connected part, then this paper expounds devices working principle. This paper completes the structure machine parts structure of design based on function modular design. Strength analysis and calculation are made to the key mechanism for device. Based on work of the device, this paper establishes hydraulic system loop and draws figures of the hydraulic system. At present, the wellhead pressure of twist tension has been carried out for three-month on field trial that proves the device is strong reliable and well-functioning. So oil field downhole tools may meet the test requirements.【关键词】井口拉压扭装置 结构设计 静力学分析 动力学分析 液压系统【英文关键词】Wellhead tension and compression twist device Structure design Static analysis Dynamics analysis Hydraulic system【目录】井口拉压扭装置结构及液压设计摘要4-5ABSTRACT5目录6-8第一章 绪论8-121.1 引言81.2 课题来源及意义8-91.3 井口拉压扭装置的发展概况9-101.4 本论文的主要研究内容10-111.5 本论文的重点和难点11-12第二章 井口拉压扭装置总体方案的研究12-152.1 井口拉压扭装置的总体方案12-132.2 井口拉压扭装置的设计要求13-142.2.1 总体技术要求132.2.2 具体技术要求13-142.3 井口拉压扭装置的技术指标142.4 本章小结14-15第三章 井口拉压扭装置关键结构设计15-273.1 拉压主机15-183.1.1 拉压主机结构设计15-163.1.2 拉压主机主要参数的计算16-183.2 液压夹具18-203.2.1 液压夹具结构设计183.2.2 液压夹具主要参数的计算18-203.3 井口夹紧装置20-213.3.1 井口夹紧装置结构设计203.3.2 井口夹紧装置主要参数的计算20-213.4 车轮装置21-243.4.1 车轮装置结构设计21-223.4.2 车轮装置主要参数的计算22-243.5 扭钳行进装置24-263.5.1 扭钳行进装置结构设计24-253.5.2 扭钳行进装置主要参数的计算25-263.6 本章小结26-27第四章 拉压主机结构分析27-344.1 拉压主机中材料的选择274.2 拉压主机动力学分析27-294.2.1 拉压主机的模态分析27-294.2.2 拉压主机的瞬态动力学分析294.3 拉压主机静力学分析29-334.3.1 拉压主机在惯性加速度下的静力学变形30-314.3.2 拉压主机在拉力作用下的静力学变形31-334.4 本章小结33-34第五章 井口拉压扭装置液压系统设计34-485.1 液压系统概述34-355.1.1 液压系统的优点345.1.2 液压系统的结构及组成34-355.2 液压系统的设计步骤35-375.2.1 明确系统的设计要求355.2.2 分析系统工况35-365.2.3 确定主要参数36-375.2.4 拟定液压系统原理图375.2.5 验算液压系统性能375.3 井口拉压扭装置液压部分37-455.3.1 井口拉压扭装置液压油源部分38-415.3.2 液压夹具部分液压系统设计41-425.3.3 拉压部分液压系统设计42-435.3.4 夹紧部分液压系统设计43-445.3.5 套管钳部分液压系统设计44-455.4 井口拉压扭装置电气控制系统45-475.4.1 装置PLC部分455.4.2 电控柜45-465.4.3 扭矩控制仪465.4.4 控制面板46-475.5 井口拉压扭装置的操作动作和互锁关系475.6 本章小结47-48第六章 结论48-536.1 本
