【摘要】：本文研究了国内外油田及相关公司机构研究开发的油田环保作业技术的发展历史及发展趋势,确定了油田环保作业井口配套装置的研究方向。根据大庆油田采油八厂油田环保作业的功能需求,结合采油八厂井口作业工艺流程及现有井口作业设备使用情况,对油田环保作业井口配套装置进行研究。研制了法兰定位式、整体式和分体式三种油田环保作业井口配套装置。油田环保作业井口配套装置采用分模块的方式进行结构设计,利用管线将各个模块连接,达到快速、高效及协调作业的目的。该配套装置主要包括井口简易平台装置、油管刮油器、抽油杆刮油器。研制的井口简易平台装置,包括井口简易平台和井口集油槽两部分,环境适应性强,有效的收集了溢出井口的油液。根据井口简易平台实际作业环境,提出平台分析的新方法,并对其进行安全稳定性校核。研制的油管刮油器、抽油杆刮油器,在进行油管、抽油杆起出作业时,实现油管、抽油杆在线刮油。基于ANSYS计算软件,研究胶芯径向变形量、胶芯硬度对刮油胶芯力学行为的影响规律。探究油管和抽油杆与刮油胶芯间产生的接触压力与胶芯径向变形量的关系,油管和抽油杆与刮油胶芯间产生的接触压力与胶芯硬度的关系。完成油田环保作业井口配套装置现场试验,验证井口配套装置的实用性,各个功能模块的操作协调性。
[Abstract]:In this paper, the development history and development trend of oilfield environmental protection operation technology developed by domestic and foreign oilfields and related companies are studied. The research direction of well head matching equipment for oil field environmental protection operation is determined. According to the functional requirements of environmental protection operation in Daqing Oil recovery Plant No. 8 Oilfield, combined with the well head operation process and the use of existing wellhead operation equipment in No. 8 Oil recovery Plant, This paper studies the matching device of oil field environmental protection operation wellhead, develops three kinds of oil field environmental protection operation wellhead matching device, flange positioning type, integral type and split type. The oil field environmental protection operation wellhead matching device adopts the method of module to carry on the structure design. Each module is connected by the pipeline to achieve the purpose of fast, efficient and coordinated operation. The matching device mainly includes the well head simple platform device, the tubing oil scraper, the sucker rod oil scraper, and the developed well head simple platform device. It includes two parts: the simple well head platform and the well head oil gathering tank, which have strong adaptability to the environment, and effectively collect the oil flowing from the well head. According to the actual working environment of the well head simple platform, a new method of platform analysis is put forward. The oil tubing wiper, sucker rod oil scraper, oil tubing and sucker rod wiping are realized when the tubing and sucker rod are up and out. Based on the ANSYS software, the radial deformation of rubber core is studied. The influence of hardness of rubber core on mechanical behavior of rubber core is studied. The relationship between contact pressure between tubing and sucker rod and rubber core and radial deformation of rubber core is investigated. The relationship between the contact pressure between tubing and sucker rod and the rubber core and the hardness of rubber core. The field test of well head matching device for oil field environmental protection operation is completed to verify the practicability of well head matching device and the operation coordination of each function module.
