The company has a group of cooperation teams engaged in the Truck Mounted Workover Rig industry for many years, with dedication, innovation spirit and service awareness, and has established a sound quality control and management system to ensure product quality.
The automatic operation equipment for minor workover is mainly composed of a wellhead operation device, hydraulic elevator, pipe and rod transmission and arrangement device and electro-hydraulic control system.
Each part of the device has different structural forms and can be selected arbitrarily for personalized configuration according to the needs of users.
1). Device introduction
The device adopts the structural form of dispersing the functional modules and integrated installation on the workover rig: with the hydraulic tong, manipulator and anti splash snap device set on the derrick of the workover rig, which can expand and rotate, and the safety slip is installed above the BOP.
2). Device features
The device only needs to install safety slips, which realizes rapid installation and migration and shortens the auxiliary working time. The device has the function of moving back and forth, left and right, which is convenient to align the wellhead. The height of the hydraulic tong is adjustable and can adapt to the wellhead with different heights. Hoisting equipment and special transport vehicles are not required for the installation and removal of the device.
1). Device introduction
The pipe and rod transportation and arrangement device has the functions of automatic delivery, arrangement and length measurement of tubings, etc.
Applicable pipe string：ID Φ60-114mm，L 8-9.7m, Pipe string weight：300 Kg
2). Main model
In addition to its main function of suspending the pipe string, it also has the functions of automatic tubing mouth match, make-up and break-out, and is also equipped with a guide device bearing reverse torque, which can realize the functions of automatic well washing, sand flushing, drilling, grinding and milling.
Main function: connect to the wellhead flange and clamp the pipe string. Slip teeth are common with other manufacturers for easy replacement. The hydraulic cylinder is clamped and the pipe string is forced to be centered. The clamping is reliable and convenient for automatic operation. Open and close state detection, and realize safety interlock with other equipment.
1）Electric control system
The main electric control box can be installed on the operation vehicle or integrated into the modular wellhead operation device. The make-up torque of various oil pipes is set on the touch screen to realize automatic make-up and break-down. Equipped with video monitoring, process prompt, safety alarm, etc. The control system has a perfect action interlocking function to ensure the safety and reliability of the workover operation process. All of the electric cabinets, sensors, connectors meet the requirement of Explosion-proof on field.
2). Hydraulic system
The hydraulic system includes hydraulic source, wellhead automatic operation device control valve group, hydraulic elevator, hydraulic slip valve group, conveyor control valve group and pipeline, etc.
Equipped with the best explosion-proof solenoid valve of domestic, which meets the explosion-proof requirements of the field.
The hydraulic source can be integrated into the conveyor or the workover rig hydraulic source can be used.
With heating and cooling functions to provide a stable power source for the normal operation of automation equipment.
The pipeline adopts quick change connector, which is convenient and fast to connect.
