The embodiments of the invention provide a power tong control method and system, and relate to the technical field of power tong control. The problem that an existing power tong cannot judge the counter-leaking position in real time is solved. The power tong control method is used for controlling the power tong control system, and the power tong control system comprises power tongs. The power tongcontrol method comprises the following steps that the rotation speed of the power tongs is obtained; and the theoretical counter-leaking position and the practical counter-leaking position of the power tongs are output according to the rotation speed of the power tongs. The power tong control system comprises a controller. In the screwing on and screwing off process, and corners of the power tongs can be calculated by measuring rotation information of a power shaft, so that the theoretical counter-leaking position of the power tongs is calculated; and in the counter-leaking process, through the rotation information of the power shaft, the rotation speed and the corners of the power tongs are obtained, until counter leakage of the power tongs is finished, the practical counter-leaking position of the power tongs can be obtained, the counter-leaking position of the power tongs is obtained in real time, and the counter-leaking effect is improved.
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...
