Vehicle-mounted automatic hydraulic oil pipe clamp device

Abstract

This patent relates to a vehicle-mounted fully automatic hydraulic tubing tong device for petroleum workover. The whole set of device is composed of five parts: oil pipe tong, workbench and running guide rail, automatic elevator and slips, hydraulic system, and PLC control system. The oil pipe tong and its slider can realize the horizontal feed of the oil pipe tong on the running guide rail under the thrust of the hydraulic cylinder. The workbench and running rails are connected to the vehicle-mounted workover frame through shafts and horizontal support plates, and the horizontal height can be adjusted through vertical hydraulic cylinders. The PLC control system controls the electromagnetic reversing valve by analyzing and processing the signal detected by the sensor, and completes the automation of the whole process of make-up and breakout, tubing clamp to gap, feed and withdraw, tubing clamping and fixing during workover operations. When the device is not working, the tubing tongs can be removed, and the workbench can be folded onto the workover rig frame. The operator is kept away from the wellhead during the workover operation, which improves the working environment of the workers and improves the automation and efficiency of the entire tubing tong workover.

Description

technical field [0001] The invention relates to a vehicle-mounted fully automatic hydraulic tubing tong workover device, which is used for improving the workover speed and improving the working environment of workers during petroleum operations. Background technique [0002] As most of my country's oilfields enter the middle and late stages of development, oil recovery becomes more and more difficult, techniques and well conditions become more and more complex, and workover tasks in oilfields become more and more arduous. However, the technical equipment and operation process of the current oilfield workover operations determine that the labor intensity of the wellhead operators in the workover operations is very high, and there are great safety hazards in manual operations during the work process. A certain number of accidents occur in the oilfield workover operations every year. worker casualties. The make-up and break-out operation of the pipe string is a key link in the...

AI Technical Summary

Problems solved by technology

The outstanding advantage of the existing open-type hydraulic tongs is that the tong head is open and has good flexibility. After each make-up or breakout, the pipe string is immediately withdrawn without hindering other operations at the wellhead, so it is widely used by domestic and foreign users. However, in In the existing workover operations, this kind of manually operated open-type hydraulic tongs and reversible elevators are used to work. Since the work tongs weigh hundreds of kilograms and are hung on the workover frame, they need to be manually pushed or moved out of the wellhead, and the elevators and lifting rings also need Frequent switching, resulting in very high labor intensity

In a word, use this existing work tongs to work, the work efficiency is low, the labor intensity of the workers is large, and the safety is poor
