【摘要】：油田环保修井作业配套集成装置主要用于油田修井起下管、杆作业过程中,防止污油污水流落地面,造成井口及周边环境污染。本文对该配套集成装置的结构进行了详细的设计与分析,阐述了现场作业工艺流程,通过油田修井作业现场试验,验证了配套装置设计的合理性。油田环保修井作业配套集成装置主要包括轮式集装箱、污油污水回收装置以及动力与控制系统等三部分。考虑修井作业井场的布置和设备搬迁移运过程的方便性,将集成技术应用到配套系列装置的方案设计中,采用模块化方式进行设计,模块之间的联接管线在现场作业实施前进行连接,等作业完成后拆离管线然后装入轮式集装箱,能保证搬迁时的整备性。在轮式集装箱顶部及四周开设有集装箱门组件,便于各模块的装载与搬卸,在污油污水收集装置中设有两个10kW电加热器,避免储液箱内油污因气温较低时流动性变差而难以排出的问题。在动力系统中设有专用液压站,用于驱动油管原油自吸装置与油管猫道清洁装置,在液压站上还设有备用接口,用于后期功能扩展。控制系统通过PLC程序控制,主要用于实现加热器、液压泵、吸入泵、输送泵的启、停控制、溢流阀的加载与卸荷控制以及换向阀的换向控制。应用有限元分析软件,模拟轮式集装箱车架在满载弯曲与满载扭转工况时的受力情况,进行了静力学分析,在自由模态下对车架进行了动力学分析,对轮式集装箱车轴进行了垂直弯曲刚度与垂直弯曲静强度分析。在油田修井作业现场进行了配套装置的拆卸安装与装载试验、液压系统控制试验以及污油污水回收装置收集与加热试验,现场试验结果表明油田环保修井作业配套集成装置具有良好的环保性能,铺设防渗布后,能保证作业原油100%不落地。
[Abstract]:The integrated equipment for environmental protection workover in oil field is mainly used in oil field workover to raise and down the pipe and in the process of rod operation to prevent the polluted oil from flowing down the surface. This paper gives a detailed design and analysis of the structure of the integrated equipment, expounds the field operation process, and passes the field test of the workover operation in the oil field. The rationality of the matching device design is verified. The integrated equipment for oil field environmental protection workover mainly includes wheeled container. Considering the layout of the workover well site and the convenience of the equipment removal and transportation process, the integrated technology is applied to the scheme design of the supporting series of equipment, which includes three parts: the recovery device for sewage oil and the power and control system, and so on, considering the layout of the workover well site and the convenience of the equipment removal and transportation process. The connection pipeline between the modules is connected before the implementation of the field operation. After the operation is completed, the pipeline is removed and loaded into the wheeled container. The container door assembly is arranged on the top of and around the wheel container to facilitate the loading and unloading of each module, and there are two 10kW electric heaters in the sewage water collection device. To avoid the problem that the oil pollution in the tank is difficult to be discharged because of the poor fluidity when the temperature is low. A special hydraulic station is set up in the power system to drive the tubing crude oil self-priming device and the tubing cat road cleaning device, and the hydraulic station is also provided with a spare connection. For later function expansion. The control system is controlled by PLC program, mainly used to realize the start and stop control of heater, hydraulic pump, suction pump, transportation pump, The loading and unloading control of the relief valve and the reversing control of the directional valve are carried out. The static analysis of the wheel container frame under full load bending and full load torsion is carried out by using the finite element analysis software. The dynamic analysis of the frame is carried out under the free mode, the vertical bending stiffness and the vertical bending static strength of the wheel container axle are analyzed. The control test of hydraulic system and the collection and heating test of waste water recovery device show that the integrated equipment for environmental protection workover in oil field has good environmental protection performance. After laying the impermeable cloth, 100% crude oil can not fall to the ground.
