Development and Application of XXJ20Y Electric Workover Rig for Slant Well
In order to meet the requirements of workover operation of slant horizontal wells and verify the tech-nological 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 devel-opment of the workover rig,especially the innovated tubing transportation structure and process,provides refer-ence for the development of slant well workover rig and electric workover rig as well as the automation transformation of conventional workover rigs.
