Abstract

The invention discloses a power tong control system for a workover rig. A power tong comprises a main tong body and a back tong body. The power tong control system comprises a hydraulic pump, a controller, a hydraulic proportional valve, a gear shifting valve and a main tong parameter sensor, wherein the hydraulic proportional valve is configured to distribute power oil provided by the hydraulic pump to a main tong motor and a back tong oil cylinder according to the preset flow and flow direction under the control of the controller; the gear shifting valve is configured to change the transmission mode of a main tong transmission mechanism under the control of the controller so as to adjust the rotating gear of the main tong body; the main tong parameter sensor is configured to detect the operation parameters of the main tong body; and the controller is configured to control the hydraulic proportional valve and the gear shifting valve in real time based on the main tong operation parameters detected by the main tong parameter sensor so as to adjust the operation state of the main tong body and / or the back tong body. The invention further discloses an operation method of the power tong control system and the petroleum workover rig comprising the power tong control system.

Description

technical field [0001] The present invention relates to the field of petroleum drilling and workover machines, and more specifically, relates to a power tong control system for a workover rig, a workover rig including the power tong control system, and an operation method of the power tong control system. Background technique [0002] In the process of oil extraction, workover operation is one of the important links. At present, most of the workover rigs in oilfields at home and abroad are manually operated and manually detected and positioned. A small number of automatic workover rigs are also semi-automatic. The key actions still need to be judged by the experience of the operator, which greatly increases the workload of manual work and reduces the production efficiency. And affect the personal safety of workers. [0003] Therefore, there is an urgent need to develop an advanced and reliable fully automatic workover equipment to maximize the efficiency of oil extraction a...
