Description

A kind of oil field plateau pumping unit adjusting device

Technical field

The utility model is the device on oil field pumping well, be oil pumper lift power position not with well head center Device when with one heart for mobile adjustment oil pumper, specifically a kind of oil field plateau pumping unit adjusting device.

Background technology

In the pumpingh well of oil field part, the big oil pumper of plateau type is mounted with, when the well for being mounted with this oil pumper needs to make During industry, first have to this oil pumper removing well head, after operation is finished, then this oil pumper is moved back to original position.At present at the scene This oil pumper is removed to the method being moved back to be workover rig or bull-dozer with big power to promote or drag completion, by its institute Equipment is big, after oil pumper is moved back to, the position of the active force of oil pumper lifting sucker rod not with pumping well head device Coaxial line, makes the polished rod sealer on the oil pumping polish rod and wellhead assembly that are moved with oil pumper synchronous reciprocating there are eccentricity issues, The oil pumping polish rod pumped produces eccentric wear with polished rod sealer, the seal in polished rod sealer is worn quickly, On the one hand need frequently to change the seal in polished rod sealer, increase the management workload of oil well；On the other hand changing close Need to stop well operation during sealing, load business oil well production is stopped sinking after the sand grains after well on pump in oil pipe, easily causes the oil pumping of sand card Pump, change seal after can not again opening well and making production, it is necessary to upper well workover will in well instrument all propose exclude sand cards after could recover Production, it will produce heavy economic losses；Another further aspect seal consumption is big, and production cost is high, and the economic benefit of oil well is deteriorated； Also on the one hand it is that well head oil leak is serious, loses crude oil, cause ground environment to pollute, the oil gas of leakage can also trigger ground thing Therefore.

The content of the invention

The purpose of this utility model is a kind of design oil field plateau pumping unit adjusting device, overcomes above-mentioned problem, Allow its oil field plateau oil pumper conveniently adjustment position, make the position of the lifting active force of oil field plateau oil pumper Keep at any time concentric with wellhead assembly, it is to avoid with sealing machine for oil well polish rod eccentric wear occurs for oil pumping polish rod, improve polished rod sealer The usage cycles of middle seal, reduce oil well and stop the well time, reduce oil well management difficulty, improve oil well economic benefit.

What the purpose of this utility model was realized in：Including wellhead assembly, oil pumper active force hanger, plateau oil pumping Machine, dilatory stake, oil-pump base, oil pumper active force hanger are arranged on the oil pumper of plateau, and plateau oil pumper is arranged on and taken out There is dilatory stake on the basis of oil machine, on oil-pump base, oil pumper active force hanger is in the top of wellhead assembly, in dilatory stake Upper installation adjusting device, the thrust part of adjusting apparatus withstands the side of plateau oil pumper.

Adjusting apparatus includes force-transmitting pole, hydraulic means, bracket, upper collar, lower collar, attachment bolt, upper collar, lower collar It is buckled in after closing up in dilatory stake, upper collar, lower collar is linked into an integrated entity by attachment bolt it is fixed in dilatory stake, upper collar Top force-transmitting pole is installed, the side mounting bracket of force-transmitting pole lays hydraulic means on bracket, and hydraulic means withstands plateau oil pumping The side of machine.

Screwed hole is arranged at the top of force-transmitting pole, and the thrust bolt of cooperation, the head of thrust bolt are installed in described screwed hole Portion is in the left side of force-transmitting pole, and the side of plateau oil pumper is withstood at the body of rod end of thrust bolt, and the head of rotary thrust bolt is pushed away Power bolt can on force-transmitting pole left and right displacement.

The beneficial effects of the utility model are：The installation adjusting device in dilatory stake, has had using oil-pump base Dilatory stake makes it be applied to the active force in adjusting apparatus and acted on the oil pumper of plateau, make plateau as the strong point of stress Oil pumper produces movement, it is adjusted to correct position, makes the center of oil pumper active force hanger and the center of wellhead assembly Overlap, on the oil pumper band of plateau during whole accessory oil pumping, the polished rod of pumpingh well and the axis of polished rod sealer are concentric, will not occur Seal durability in eccentric wear, polished rod sealer is long, it is not necessary to frequently change seal, it is to avoid what be presently, there are is various Problem, it is possible to reduce oil well stops the well time, reduces oil well management difficulty, improves oil well economic benefit, with significant economic effect Benefit and social benefit.The utility model is simple in construction, and processing cost is low, easy to use, and adjustment oil pumper displacement is time saving, laborsaving, Application easy to spread.
