Description
Technical field:
The present invention relates to a kind of engineering equipment that is used for oilfield oil well well workover and underground work.
Background technology:
Production rig is the capital equipment that carries out underground work in oil field oil, the well manufacturing process.Conventional workover rig as engine, is divided into two-way by its power of main-gear box with Diesel engine, and the winch drum gearbox of leading up to drives the cylinder rotation, has finished, the lower tubular column operation; Another road drives the workover rig walking by central control mechanism.Well workover and walking are not worked simultaneously.Conventional workover rig is through updating, and performances such as its operating rate hoisting power satisfy the needs of oil well repairing operation substantially, utilize unreasonable and other unsatisfactory part but remain at energy, as:
1, the rated power of conventional workover rig has reached 160-269 kilowatt, and the time that can use rated power in workover treatment seldom, causes the waste of capacity of equipment;
2, the crawler belt working rig does not carry derrick owing to characteristics own, and the migration performance is bad;
3, fuel consume is higher;
4, operation field noise height;
5, owing to the too fast security incident hidden danger of easily bringing of lowering velocity, the heat radiation of winch brake hub is bad, influences its application life.
At present, electric workover rig has two types basically: a kind of is the electric hydaulic energy-storing workover rig, adopt electronic, hydraulic drive, liquid accumulation of energy, the combined oil cylinder technology that hoists, the subject matter one that exists is complex structure, liquid, gas element are as main working parts, the required precision height, maintenance difficult; The 2nd, the accumulation of energy time is not enough, and energy-saving effect is undesirable; The 3rd, be difficult to satisfy fully the site work requirement in the speed control.Another kind is electronic AC frequency conversion workover rig, though can realize infinitely variable speeds and energy-conservation within the specific limits, the load range of workover rig is big, is difficult to realize infinitely variable speeds in whole load range; In addition, frequency converter cost height requires height to working environment, needs specialized maintenance, and the on-the-spot use of well workover in the open air also needs the test through practice.
Summary of the invention:
The object of the present invention is to provide a kind of electric hydraulic pressure workover treatment machine of controlling convenience, high efficiency, good energy-conserving effect.
Technical scheme of the present invention is as follows:
The present invention adopts two power sources, with the well site industrial power is main power source, with the motor drives variable pump is the power unit, utilize hydraulic oil to be driving medium, drive the low-speed big torque motor rotation, then by the winch drum gearbox, the rotation of drive cylinder, power is sent to the hoisting system of workover rig by being wrapped in wire rope on the cylinder, under the control of electricity, liquid control system, finishes predetermined work.The Diesel engine of car at the bottom of the workover rig as back-up power source, when on-the-spot no power or power system are gone wrong,, is driven permanent power and variable pump and provides power for low-speed big torque motor by the transfer speed change system with this motor, finish predetermined work.
This kind electric hydraulic pressure workover treatment machine is made up of end car, winch, derrick and traveling system, operating room, motor, hydraulic variable displacement pump, gearbox and hydraulic motor, multiple directional control valve, motor transfer case, hydraulic oil container, control valve group, hydraulic pressure puffer, cable drum, regulator cubicle, brakes, electric-control system and accessory system, winch is arranged on end car postmedian, the one side is provided with gearbox and hydraulic motor and multiple directional control valve, and derrick and traveling system, operating room and hydraulic pressure puffer are separately positioned on car rear portion, the end; Car front portion, the end is provided with driver's cabin and motor, and its both sides, rear are respectively equipped with the high and low pressure regulator cubicle, and is provided with accumulator and cable drum, and end car middle part one side is provided with motor and hydraulic variable displacement pump, and opposite side is provided with hydraulic oil container, and the centre is provided with the control valve group; Brakes, electric-control system are separately positioned on each workpiece corresponding site of workover rig, and accessory system mainly is supporting leg and a hydraulic tongs before and after the end car, is separately positioned on car front and rear part, the end.During the oil-water well workover treatment, after by end car this workover rig being reached operation field and docks to the appropriate location, the well site power supply is received on the regulator cubicle, close a floodgate then and connect two groups of motor-driven hydraulic pumps work, hydraulic pump is sent to hydraulic valve piece and integrated plate from hydraulic oil container pump oil, enter hydraulic control system, make the front and back hydraulic support leg support the ground bearing load by multi-way control valve, then make hydraulic jack that derrick is stretched out rotation by control valve and erect the recoil on derrick base, after fixing bearing pin, utilize control valve that derrick is increased to 18m again, fix pivot pin and derrick guy wire, preparation then is installed finishes.
During normal rountrip, operator is seated in the operating room, by hand control valve control hydraulic valve piece, make hydraulic oil action as required arrive the hydraulic motor of winch one side, drive gearbox, the positive and negative rotation of cylinder, finish by system's of removing (wire rope, derrick travelling block) again and remove pipe, bar operation; During the rountrip brake, can effectively control rountrip speed by the water brake joystick in the operating room.In normal rountrip process, the portion of energy of hydraulic system enters in the accumulator and stores, and when system needed energy supplement, the gases at high pressure in the accumulator expanded, and hydraulic oil is refluxed add in the system.------the rotation derrick lowering is to car---supporting leg before and after packing up---cuts off the removal of home of can driving away of switchbox power supply to derrick retracting after operation finishes, to receive guy wire according to the reverse order of preparation.
Electric hydraulic pressure workover treatment machine convenient operation and control provided by the invention, adopt pump control system, no restriction loss, energy consumption is little, energy utilization rate and high efficiency, energy-saving effect is obvious, lacks at the scene under the situation of power supply also can utilize stand-by power work, guarantees normally carrying out of oil-water well workover treatment.
