The utility model belongs to technical field of petroleum extraction, is that a kind of what be arranged on ground is the pumping unit of well of power with linear electric motor.
Now, what the pumping unit overwhelming majority in oil well ground adopted is that electric rotating machine is a power, by retarder and rotation motion to linear device, drives oil pumping polish rod and sucker rod and pumps, and drive the purpose that the down-hole oil production pump reaches oil recovery.The pumping unit that with the electric rotating machine is power is bulky, complex structure, and consumed power is many.Chinese patent application number is 96217638.9 utility model patent, discloses a kind of " adopting the pumping unit of linear motor driving ".What this technological scheme adopted is that linear electric motor connect and driving sucker rod and oil extraction pump, has reduced retarder and rotation motion to linear device, and the pumping unit that has overcome existing electric rotating machine drive is bulky, complex structure, shortcomings such as big energy-consuming.This technology adopts linear motor driving, is a reasonable technological scheme.The feature of this technological scheme is: be made up of down-hole oil production pump, sucker rod and power plant, derrick, several parts of balancing weight.Power plant adopt linear electric motor, and linear motor stator electric is fixed on the wellhead assembly together with the longitudinal spacing post, and the mover upper and lower end is fixed with positioning block, leans against slidably on the edge-on limited post, is fixed with damping spring on wellhead assembly and the limited post respectively.Linear motor rotor is a hollow structure, and the center is by there being sucker rod.Sucker rod is fixed on the mover of linear electric motor together with deck.Derrick is provided with the weight balance device pulley.The wire rope two ends connect deck and balancing weight respectively by pulley.This technological scheme, linear motor stator electric is fixed on the wellhead assembly together with limited post, and a lot of inevitably shortcomings are arranged.When 1, the mover of linear electric motor pumped, the inevitable generation vibrated, and makes the linear motor driving pumping unit vibrate simultaneously.Stator and limited post are fixed on the wellhead assembly, drive the wellhead assembly vibration during mover motion, cause wellhead assembly to leak crude oil and rock gas.Even be not because vibration produces the wellhead assembly leakage, in mechanical oil pumping process, wellhead assembly produces oil, gas leakage is recurrent.If generation natural gas leaking, linear electric motor are fixed on the wellhead assembly, rock gas can directly diffuse into linear electric motor, can produce unsafe hidden danger.2, linear electric motor are fixed on the wellhead assembly, occupy pithead position, cause many difficulties can for the oil well shaft mouth operation.As change shaft mouth operations such as packing box, packing.3, linear electric motor are fixed on the wellhead assembly, and motor produces vibration, and wellhead assembly connects underground bushing, makes underground bushing be vibrated, and cause stratum vibration casing deformation.4, linear electric motor are fixed on the wellhead assembly, and wellhead assembly can not bear extraneous big pressure.If linear electric motor are fixed on the well head, match with regard to needing to redesign, make the wellhead assembly that can bear big pressure, increase oil production equipment cost input.
The purpose of this utility model is: linear electric motor are removed from wellhead assembly, can be produced hidden danger when solving the well head natural gas leaking; Solve linear electric motor and be fixed on the wellhead assembly, occupy pithead position, cause many difficult problems for the oil well shaft mouth operation; Solve the shortcoming that motor oscillating drives the underground bushing vibration; Do not change on-the-spot wellhead assembly, solve the wellhead assembly problem that bears immense pressure.With the rail brackets of linear electric motor, replace derrick.
The utility model is achieved in that a kind of pumping unit of linear motor driving that adopts is made up of institutes such as rail brackets, electric mover, motor stator, chain, sprocket wheel and balancing weights, it is characterized in that: rail brackets is a frame shape, motor stator is fixed on the rail brackets inboard, and the rail brackets inboard is fixed with the electric mover guide slide.The slide block that cooperates with slideway is arranged on the electric mover.The roof anchorage of rail brackets has sprocket wheel.Chain is by sprocket wheel, and an end is fixed on electric mover top, and the other end is connected with oil pumping polish rod in the well mouth of oil well device.The electric mover bottom is connected with counterweight chain one end.The counterweight chain is by the counterweight sprocket wheel of a frame bottom sprocket wheel and a top of the trellis, and the other end connects balancing weight.Sprocket wheel among the application can be substituted by pulley, and its chain changes wire rope accordingly into.Sprocket wheel and chain or pulley and wire rope, this dual mode all belongs to the application's technological scheme.
Adopt the advantage of technical solutions of the utility model to be, linear motor rotor top has chain to connect, and chain is by sprocket wheel, and the other end is connected with the oil well oil-pumping polished rod.Wellhead assembly separates with linear electric motor with sucker rod, and linear electric motor are removed from wellhead assembly, and during the well head natural gas leaking, rock gas can directly not enter in the linear electric motor, has solved the hidden danger in producing.Linear electric motor are not installed on the wellhead assembly, still adopt on-the-spot original wellhead assembly, the workman when shaft mouth operation, with electric rotating machine be that the pumping unit of power is convenient equally.Linear electric motor produce vibration in when work, can not influence underground bushing and solve the wellhead assembly problem that bears immense pressure.With the rail brackets of linear electric motor, replace the pumping unit structure that derrick has also been simplified linear motor driving.
