Embodiments of the present invention provide a power tong control method and system, which relate to the field of power tong control. The purpose is to improve the problem that the existing power tongs cannot judge the position of the gap in real time. The power tong control method is used to control the power tong control system, the power tong control system includes the power tong, and the method includes the following steps: obtaining the rotational speed of the power tong; Lack of location. The power tong control system includes a controller. In the process of make-up and break-out, by measuring the rotation information of the power shaft, the rotation angle of the power tong can be calculated, and then the theoretical matching position of the power tong can be calculated; The rotation speed and rotation angle of the power tongs are obtained, and the actual matching position of the power tongs can be obtained until the matching of the power tongs is completed, and the matching position of the power tongs can be obtained in real time, so as to improve the matching efficiency.
Description
technical field [0001] The present invention relates to the field of power tong control, in particular to a power tong control method and system. Background technique [0002] During workover, oil pipes and drill pipes need to be made up and down. At present, open-type power tongs are used in oil fields. When making up or breaking out, reverse rotation is required to align the gap. Withdraw from the column to proceed to the next step. In the related art, when the power tongs are aligned, it is necessary to make a quick turn to allow the jaws of the hydraulic tongs to retreat, and then switch to a low gear, reverse slowly, and detect the alignment position. [0003] The above-mentioned alignment method has the following disadvantages: the alignment position cannot be detected in real time, the specific position of the gap cannot be accurately judged after the power tong decelerates and stops, and when the size of the oil pipe is large, the phenomenon of oil pipe jamming ofte...
