It is characterized in that: be fixed with the top fixed pulley at the top of derrick, be fixed with two traveling sheaves in the power swivel bilateral symmetry.Plan range well head center left 1000～1200mm fixes a bottom fixed pulley in the place on rig floor, a wire rope dead line anchor is fixed at 1000～1200mm place, right side, plan range well head center on rig floor, and a hydraulic wireline winch is fixed in the left side, plane on rig floor.Auxiliary pressurization wire rope one end is fixed on the wire rope dead line anchor, auxiliary pressurization wire rope is walked around two fixing on power swivel traveling sheaves successively, auxiliary pressurization wire rope is walked around the bottom fixed pulley again, auxiliary pressurization wire rope is walked around the top fixed pulley again, and the other end of auxiliary at last pressurization wire rope is wrapped on the cylinder of hydraulic wireline winch.In the time of the auxiliary pressurization of needs, start the auxiliary pressurization function that hydraulic wireline winch can be realized drilling well.By the control hydraulic wireline winch of hydraulic system, can realize accurately pressurization in the 0-6t scope.
Traveling sheave and power swivel welding are fixing.
Bottom fixed pulley and wire rope dead line anchor and rig floor adopt bolt.
Described hydraulic wireline winch is a 3t hydraulic wireline winch.
The beneficial effects of the utility model: the utility model oil, the auxiliary water booster system of coal-bed gas exploitation drilling well, can oil, the function of the auxiliary pressurization of coal-bed gas exploitation drilling well 0-6t, improve a game clock layer drilling efficiency, the difficulty that solves some tubing strings is lowered to problem, improves drilling efficiency.
