Description
Technical Field
The utility model belongs to the technical field of logging winch equipment, concretely relates to logging winch system.
Background
The logging winch is widely used in oil field logging companies, and is equipped with different downhole devices for logging operations or perforating operations. When the instrument or the perforating gun passes through a vertical well section of an oil well during the production operation of a highly-deviated well and a horizontal well, the instrument or the perforating gun can descend by the self gravity; when the horizontal well section is operated, the horizontal well section cannot descend to the bottom of the well by means of the gravity of the horizontal well section. High-pressure and large-flow pumping liquid is provided by fracturing equipment, and a cable head, a tension short joint and an instrument (or a perforating gun) are driven to run towards the bottom of an oil well.
The traditional control mode is that the tension of the cable is observed by depending on the experience of an operator, when the tension of the cable is increased, a control handle is quickly adjusted, the rotating speed of a winch roller is increased, and the cable is quickly released; when the tension of the cable is reduced, the control handle is adjusted, the rotating speed of the winch drum is reduced or stopped, and the lowering speed of the cable is reduced or stopped. Because the pressure of the pumped liquid is high and the flow rate is large, if the experience of an operator is insufficient or the reaction is not timely, the cable can be broken, or the cable is excessively lowered and wound in an oil well to damage the cable, and the cable can be broken when the cable is lifted up again. A great loss will be caused by a slight careless operation
Because the well conditions in the oil well are complex, the resistance of the cable in the oil well is different, particularly at the corner of the vertical end and the horizontal well section of the oil well, the cable inevitably generates friction with the wall of the oil well, and the friction force cannot be accurately calculated; the cable may also be attracted to the borehole wall by downhole fluids. Because the cable tension meter is installed on the ground, the difference between the cable tension observed by an operator and the tension applied to the end of the underground instrument is large, and the production accidents of breaking the cable and damaging the cable are easily caused.
