摘要
为满足斜直水平井修井作业需求和验证斜直井作业工艺参数,研制了XXJ20Y电动斜直井修井机。介绍了修井机的主要结构和原理,提出将油管作业空间由后端移至机身内的思路。创新对中方法和油管运移及摆放路线,设计相应的整机对中结构、井架结构和抓管、移管、排管结构。应用Pro/E和ANSYS Workbench 15.0等主流分析软件对井架和底座等关键零部件进行了三维建模和强度校核。该修井机进行了小规模的试验应用,达到了较高的自动化水平,操作手1人就可完成管柱起下作业,配合人员大幅减少,安全性提高;利用井场电源驱动,尾气零排放、噪声低,绿色环保;优化了油管运移结构及流程。该修井机的研制可为斜井修井机、电动修井机的研制和常规修井机的自动化改造提供借鉴。
In order to meet the requirements of workover operation of slant horizontal wells and verify the technological parameters of slant well operation,a XXJ20Y electric workover rig for slant well was developed.The main structure and principle of the workover rig were introduced,and the idea of moving the tubing operation space from the back end to the body was proposed.The alignment method and tubing transportation and placement routes were innovated,and corresponding overall alignment structure,derrick geometry and pipe grabbing,moving and racking structures were innovated.The mainstream analysis software such as Pro/E and ANSYS Workbench 15.0 were used to conduct 3D modeling and strength check on key parts such as derrick and substructure.The workover rig was tested and applied on a small scale,achieving a high automation level:one operator can complete roundtrip of pipe string,greatly reducing the number of cooperating personnel and improving safety.The workover rig was driven by power at well site,realizing zero exhaust emission,low noise and environmental protection.The development of the workover rig,especially the innovated tubing transportation structure and process,provides reference for the development of slant well workover rig and electric workover rig as well as the automation transformation of conventional workover rigs.
