Description
Technical field
What the utility model oil well pumping-assistant device related to is a kind of air extractor that reduces oil well casing air pressure, is the servicing unit of oil field beam pumping unit intensified oil reduction, also is applicable to other occasions of need bleeding, and bleeds or compresses pumped gas and use.
Background technology
The matching used well head single-acting decompression of the beam pumping unit pumping-assistant pump of the usefulness of oil field oil pumping at present is made up of connecting rod, plunger, cylinder body, valve, intake and exhaust gate valve, two exhaust-valves, two one way valves, this installs complicated operation, never allow liquid to pass through, otherwise can produce liquid hit phenomenon, badly damaged associated components, moreover, its installation accuracy requires high, the plunger seal life-span is short, thereby causes pumping efficiency to reduce, even can not work.
Summary of the invention
The purpose of this utility model is to provide a kind of oil well pumping-assistant device at above-mentioned weak point, have cylinder block, piston rod, auxiliary piston, main piston, piston push-pull rod, compact conformation, easy for installation, simple to operate, suction pressure is steady, with the supporting use of oil pumper, can make the stable volume increase of gassiness oil well.
The oil well pumping-assistant device takes following scheme to realize: the oil well pumping-assistant apparatus structure comprises cylinder block, piston rod, auxiliary piston, main piston, piston push-pull rod, dirt-proof boot.The cylinder block device has piston rod, piston-rod lower end is equipped with auxiliary piston, piston rod is the cannulated piston rod, cavity is a fuel reserve tank, is provided with screen pack in the fuel tank bottom, and the auxiliary piston periphery is equipped with centering ring (guide ring), oil ring, piston push-pull rod is installed on the auxiliary piston, main piston is sleeved on the piston push-pull rod bottom, between pull bar bottom and the main piston cushion pad is housed, and the main piston periphery is equipped with oil ring, compression ring.Be provided with grease channel in the piston push-pull rod, grease channel is communicated with annular space between fuel reserve tank and main piston and the auxiliary piston.Lubrication oil enters grease channel by screen pack, enters major and minor piston, and inboard wall of cylinder block is lubricated.Between cylinder block top and piston rod, dust cover is housed, can prevents that dust from entering in the cylinder block.Gentle inferior part of the cylinder block all is equipped with the ball bearing seat on piston rod top, flexibly connects with walking beam, derrick respectively by the ball bearing seat.Cylinder block is provided with the inlet and outlet interface.
Operating principle: when the oil well pumping-assistant device uses, by the gentle inferior part of the cylinder block in piston rod top all be equipped with the ball bearing seat respectively with walking beam, derrick flexibly connects, the reciprocating motion of walking beam flexibly connects the back by ball bearing and drives on the piston rod work, the following reciprocating motion, cylinder body is fixed on the derrick of well head side after then flexibly connecting by ball bearing, the double-piston that piston rod drives in the cylinder body is (main, auxiliary piston) does toward reverting to take drugs, the exhaust campaign, by this device well casing gas is extracted out, reduce oil well casing air pressure, intensified oil reduction, the gas that is drawn out of can be used.
Oil well pumping-assistant apparatus features: piston rod hollow and tool fuel tank function; Space between the double-piston (major and minor piston) is full of lubrication oil, and piston and casing wall are lubricated; It is non-being fastenedly connected that main piston is sleeved on piston push-pull rod, is push-pull configuration, can make main piston keep concentric with cylinder body automatically; Piston push-pull rod power passes to piston by cushion pad, can avoid the cylinder liquid hit phenomenon; Dirt-proof boot can prevent effectively that ash, the sand in the atmosphere from entering cylinder body top; Piston ring packing is good, long service life.
The oil well pumping-assistant device is reasonable in design, and is easy to install, simple to operate, can overcome the accident that common plunger displacement pump can produce liquid hammer, and equipment is difficult for producing fault, reliable operation, and long service life can make steady output of oilwell, volume increase.Power when the oil well pumping-assistant device can make full use of the reciprocating motion of oil pumper walking beam must not add power source in addition, therefore, can save a large amount of energy.
