Description
Technical field
The utility model relates to a kind of underground work maintenance tool, and a kind of specifically have a double dynamical workover rig.
Background technology
Oil well repairing operation engineering difficulty is large, and technical requirements is high, must be with large-scale workover rig, and the special equipment instruments such as outfit overhaul drilling rod, overhaul rotating disk just can be carried out the work.The content general content of workover treatment has three classes: the first kind, and complicated the salvaging, so-called complicated the salvaging refers in Oil/gas Well, because a variety of causes causes the trouble of lost tool in hole situation very complicated.Give one example: certain well is all stuck down-hole string, instrument, pulls off again oil pipe when light maintenance operation team processes, can't operation, and have to hand over heavy repair task team to repair.Equations of The Second Kind, repair oil well casing, and sleeve pipe is to guarantee the normal necessary condition of producing of Oil/gas Well, and oil well often occurs because a variety of causes causes casing failure, and therefore repairing oil well casing is one of main task of heavy repair task team.Casing failure mainly contains following several situation: the one, and sleeve shrinking diameter, the casing inner diameter of oil well has diminished, and causes lower well tool can't pass, and oil well can't normally be produced; The 2nd, casing collapse, the casing collapse of oil well becomes seam or hole, causes the stratum sand to pour in well, and Oil/gas Well is stopped production; The 3rd, sleeve pipe dislocation, disconnection, some casings can fracture, and upper and lower fracture staggers.The 3rd class, CST, with macaroni band drill bit, is lowered in old casing, in precalculated position, bores and opens a window (term is " windowing "), and little drill bit creeps into outward from " window ", makes a call to a slim-hole, then descends small casing, well cementation.This from the engineering of boring outward one section slim hole completion in old casing old well sidetracking, it is applicable to following situation: old down-hole section scraps, and can not exploit, and after sidetracking, can again resume production; The oil reservoir of old well is bad, and near the oil reservoir had well can be exploited new reserves after sidetracking.
At oneself, have in technology, workover rig mainly adopts vehicle-mounted Diesel engine outputting power, through angle transmission mechanism, passes to winch, realize to promote, and its shortcoming is that the Diesel engine operating noise is large, the exhaust emission environment, expends fuel oil, and expense is high.Workover rig developed into and take the electric workover rig that pure electric power is power recent years, and its shortcoming is limited by the well site power supply capacity, sometimes can't meet the operation needs.Fuel oil, electric double power workover rig are also arranged, but motor output shaft adopts and the Diesel engine output shaft be arranged in parallel, its shortcoming is that driving-chain is long, and the system power loss is larger, and transmission efficiency is low.
Summary of the invention
The purpose of this utility model is to provide the two mixing workover rigs of power, and the power that makes workover rig of maximizing favourable factors and minimizing unfavourable ones uses to reach and rationalizes most.
To achieve the above object, the utility model adopts following technical scheme: the two mixing workover rigs of power, its structure mainly comprises: hook block, support, driving-belt, tool box, liquid lifting unit, stand hinge, spike, liquid supporting leg, air motor, diesel engine, transfer case, transmission hinge, hydraulic pressure torque converter, right angle gear box, automobile chassis, air compressor, automobile engine, be mounted with air motor, diesel engine on described automobile chassis, air motor, its power output shaft of diesel engine are connected with transfer case; Between transfer case and hydraulic pressure torque converter, by the transmission hinge, be hinged; The hydraulic pressure torque converter is connected with right angle gear box by rotating shaft; Automobile chassis, tail end are fixed with liquid lifting unit, and liquid lifting unit, spike are hinged with support respectively; Spike one end is fixed on the liquid supporting leg;
Support one end is provided with hook block, and centre position is provided with tool box, and hook block is connected by driving-belt with right angle gear box;
Between support and liquid lifting unit, by stand hinge, be hinged;
The car engine mechanomotive force is output in air compressor, and the defeated pressure-air of air compressor is in air motor.
Its rated power of above-mentioned air motor is between 5 ~ 12KW.
The beneficial effects of the utility model: air compressor is loaded in workover rig, use air motor that automobile power is switched to workover rig and uses, therefore when the diesel powered deficiency or stop working, while breaking down, can adopt air motor to realize continuing energy supply, thereby realize the gapless work of workover rig.
