Description

One many wells of machine reciprocating beam-pumping unit

Technical field

The utility model relates to the mechanical oil recovery device in a kind of oil field.

Background technology

In the oil recovery process of oil field, mechanical oil recovery is a kind of requisite means, and beam pumping unit is to use maximum class plant equipment, it drives deep well pump work by wellhead equipment by sucker rod, this wellhead equipment volume is bigger, floor space is also bigger, generally all is that a bite oil well is installed an equipment, by driving deep well pump crude oil is come out from underground mining.Oil well well spacing in the past is bigger, and general apart hundreds of rice is to several kms, and the floor space of mounting shaft jaws equipment just is not a problem in such cases, does not need special consideration.Development along with drilling technology, directional well, horizontal well drilling technology are constantly ripe, for the land occupation amount that reduces the well site and the removal charge of drilling equipment, on the loess plateau or some other area at sea on the production platform,, adopt the cluster well group at present more and more, promptly bore many mouthfuls of directional wells in a well site, the well head distance is generally at 3-8 rice.A beam pumping unit is installed on every mouthful of oil well like this to be carried out individual well, unit, singly adopts, for installation, oil mining or oil well management very big influence is arranged mutually all, also be a kind of waste, just can't install because of the place is too little on the afloat production platform at all.

The utility model content

The purpose of this utility model provides a kind of processing and manufacturing simple in structure, easy, cost is lower and can save many wells of machine reciprocating beam-pumping unit of the energy, can drive the production of recovering the oil of many mouthfuls of oil wells with a this equipment.

Technical solution of the present utility model is to realize like this, one many wells of machine reciprocating beam-pumping unit, be bound up to be installed on the frame by motor, transmission device and constitute, its special character is, (1) transmission device is made of head roll and driving-belt, and head roll is installed in the frame by axle bed, and head roll is walked around at the driving-belt middle part, the guide pulley that is installed in the frame upper end is walked around at its two ends respectively, is installed with hanger and stroke locator at the driving-belt two ends.(2) axle bed of guide pulley is installed in slide bar one end, and slide bar is installed in the sliding sleeve, and sliding sleeve is installed in the frame upper end, and hound is equipped with in the below of slide bar termination, and upper fixed has oblique rope.(3) on frame, be fixed with stroke indicator.(4) head roll connects with motor mutually by shaft coupling, and motor is connected by frequency converter, control cabinet and power supply.

In above-mentioned technical solution, its special character also is, regulates that the axle of cylinder by two ends is contained in the axle bed, axle bed is fixed on the sliding sleeve, and sliding sleeve is sleeved on the conduit, conduit is fixed on the frame, and 2 axle beds are bound up by positive and negative screw rod and positive and negative nut.

In above-mentioned technical solution, its special character is that also conduit is installed on the frame by positive and negative screw rod and positive and negative nut.

In above-mentioned technical solution, its special character is that also (1) head roll is installed on the cross bar by axle bed, and cross bar is installed on the frame by positive and negative screw rod and positive and negative nut, and the cross bar two ends are fixed on the frame.(2) head roll adopts dolioform cylinder, and cylinder surface is solidified with one deck rubber.

Usefulness of the present utility model is, (1) because this oil pumper adopts the steel cable core conveyer belt because of its wider width, its two ends can be separated into a plurality of terminations, each termination can drive a bite oil well respectively, so a plurality of (more than 2 or 2) guide pulley can be installed on a frame, the tread equipment of can realizing drives many mouthfuls of (more than 2 mouthfuls or 2 mouthfuls) oil wells and produces, and reduces the well site floor space, is convenient to the installation and the management of equipment.Because of head roll also has various diameter and width can be chosen configuration wantonly, the polished rod load that makes this oil pumper have plurality of specifications ensures the requirement of oil recovery technological production norm.(2) use this oil pumper, utilize sucker rod to pump, per two mouthfuls of oil wells not only make device structure greatly simplify mutually as the other side's counterbalance, and the power that is consumed also can obviously reduce, and energy-saving effect is obvious.(3) owing to do not have gear drive or changement on the complete machine, all adopt belt transmission, noise is low, and it is reliable to operate steadily.(4) because the many mouthfuls of shared frames of oil well have reduced heavy bascule again, can save steel, reduce cost.(5) owing to adopt the stroke locator, stroke, the stepless adjustment of jig frequency can be realized, and the long stroke pumping unit more than 6 meters can be easy to realize, reliable.(6) because the employing frequency converter is adjusted motor speed, thus be easy to change rate of pumping, and operate steadily.Do not need to install reducer, can make complete machine structure simple, weight reduction.(7) because of adopting the Steel cord driving-belt to carry out transfer motion power, and adopt 2 to regulate cylinder, the cornerite of driving-belt on head roll can be regulated, maximum can reach 320 °, can reach enough driving forces, and the excessive situation of load such as holddown appears in the down-hole, also can avoid damaging down-hole pump, break accident such as sucker rod and take place.
