Integrated vehicle-mounted snubbing operation workover rig

Abstract

The invention provides an integrated vehicle-mounted snubbing operation workover rig and aims to overcome the defects that existing snubbing operation equipment is complex in operation and high in operation cost. An engine, a hydraulic station, a hydraulic system, a winch and a derrick are sequentially installed on a chassis of the vehicle-mounted workover rig from front to back, the derrick is installed at the back of the chassis, the derrick is horizontally arranged during transportation and erected during operation, and a bracket is fixedly mounted at the tail of the chassis; a snubbing operation device and a blowout preventer stack are fixedly installed on the bracket sequentially from front to back; a driller operation box is installed at the lower end of the derrick; a folding driller platform is mounted on the derrick below the driller operation box. The integrated vehicle-mounted snubbing operation workover rig has the advantages that the workover rig is reasonable in design and convenient to operate, integrated carrying and installation, integrated control and integrated operation of snubbing workover operation can be achieved, and the operation efficiency is high; the driller operation position of the folding driller platform is close to a wellhead, the driller view is wide, and the vehicle safe driving requirement is met.

Description

technical field [0001] The invention relates to a vehicle-mounted workover rig, in particular to an integrated vehicle-mounted workover rig for pressure work. Background technique [0002] Snubbing operation is a special operation method in which professionals operate special equipment to lift and lower pipe strings in a pressurized environment. The operation is difficult and requires high safety construction. In addition to the operation control of floating hooks and auxiliary equipment, it is also necessary to operate the blowout preventer group, floating slips, fixed slips, lifting cylinders and other actuators of the pressurized operating device. In order to realize safe operation, it is also necessary to monitor the working conditions of the system such as system pressure, balance pressure and downhole pressure in real time. [0003] The equipment for snubbing operation can be divided into three parts: wellhead, hoisting equipment and power drive. According to the stru...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the complex operation and high operating cost of the existing snubbing equipment, the driller’s operating room (table) of the existing vehicle-mounted snubbing workover rig is located at the front and far from the wellhead. The erected derrick blocks the sight of the driller and is inconvenient for construction operations. The invention provides an integrated vehicle-mounted workover rig
