Description
Technical field
The present invention relates to the equipment of oil well pump detection and workover equipment, more particularly to lower oil tube with pressure and sucker rod operation.
Background technology
During inspection pump with pressure, first have to that sucker rod is risen using sucker rod trip operating device with pressure, it is now logical
Sucker rod trip operating device structure and application method with pressure are detailed in the patent ZL201010195234.8 of applicant
It is real to introduce, it is then shut off well head；Upper lower oil tube apparatus for work with pressure, pump is examined after playing flowline again.Pump is descended after the completion of maintenance again,
Utilize lower oil tube apparatus for work with pressure.Under it is complete after close well head, tape swapping pressure sucker rod trip operating device carries out lower pump
Bar.So changing well head back and forth not only wastes time and energy, but also there is potential safety hazard.The weight of sucker rod trip operating device with pressure
Amount is at 5 tons or so, and the weight of lower oil tube apparatus for work with pressure is general all more than 10 tons, change every time well head will 25T with
On crane cooperating.Therefore complete that in inspection pump with pressure sucker rod trip operating device with pressure and with pressure must be used respectively
The lower covering device of oil pipe apparatus for work two, but also to change repeatedly four times, while well head also needs to change, the labor intensity of workman,
Duty cycle, production cost and security risk etc. are all very big.
In order to overcome the disadvantages mentioned above that prior art is present, change current present situation, applicants have invented a set of equipment realization
Oil pipe and sucker rod institutional operation machine, it can meet oil well with pressure pump detection and workover technological requirement.
The content of the invention
The mesh sunlight of the present invention is to provide a kind of lower oil tube with pressure and sucker rod operation all-in-one, and it can more satisfactoryly
With pressure remove for solving sucker rod removes the problem of frequently changing well head with the with pressure of oil pipe, can be safe and reliable, economical and efficient
Realize no killing well not open flow inspection pump with pressure.
The technical scheme that the present invention takes is as follows：
A kind of lower oil tube with pressure and sucker rod operation all-in-one, it is characterized in that：Including hydraulic pressure single disc seal full preventer,
It is short that three hydraulic pressure single discs partly seal preventer, two fixed hydraulic slips, hydraulic support leg, support revolution crossbeam, two revolutions
Connect, it is lower hydraulic annular preventer, balance off-load four-way adapter, Flat Sluice of surging, the blowout prevention cylinder that stretches, clip, adapter flange, omnipotent
Sucker rod slips, upper hydraulic annular preventer, oil cylinder crossbeam, upper platform, telescopic oil cylinder, middle level platform, control cabinet and traverse
Support, hydraulic support leg and support revolution crossbeam composition lower supporting frame, support revolution relative to four hydraulic support leg energy of crossbeam
Rotate, hydraulic pressure single disc seal full preventer, lower hydraulic single disc partly seal preventer, bottom fixed hydraulic slips from bottom to top according to
On the lower surface that support revolution crossbeam is fixedly mounted on after secondary series connection, middle part hydraulic pressure single disc partly seals preventer, balance off-load four
Connect pipe, lower hydraulic annular preventer, bottom revolution short circuit are fixed on support revolution crossbeam upper surface after connecting from the top down
Between the platform of middle level, two Flat Sluices of surging are arranged on the both sides of balance off-load four-way adapter；Top revolution short circuit, top liquid
Pressure single disc half is fixedly mounted on the upper surface of middle level platform after sealing preventer and the series connection of top fixed hydraulic slips, is stretched anti-
Cylinder sleeve is sprayed mounted in the interior of top revolution short circuit, the envelope preventer of top hydraulic pressure single disc half and top fixed hydraulic slips series component
In chamber, the upper end of flexible blowout prevention cylinder is fixed on oil cylinder crossbeam by clip and adapter flange, blowout prevention cylinder lower, neck end of stretching by
Middle part hydraulic pressure single disc half seals preventer and seals and clamp, and the cylinder body of two telescopic oil cylinders is fixed on upper platform.
The operation process of actuating oil-pumping unit of the present invention is as follows：
(1) hydraulic annular preventer on universal oil pumping rod slips, that is, the annular closed between sealing sucker rod and oil pipe are closed
Space, closes well head top universal oil pumping rod slips clamping sucker rod, closes two Flat Sluices of surging, and other elements are all in and beaten
Open state, up sucker rod of telescopic oil cylinder is fricton-tight between sucker rod and upper hydraulic annular preventer, belongs to static seal, stretches
Blowout prevention cylinder stretches, and telescopic oil cylinder reaches after top dead center, closes well head bottom fixed hydraulic slips clamping sucker rod, closes lower liquid
Annular preventer is pressed, two Flat Sluices of surging are opened, will be close between lower hydraulic annular preventer and upper hydraulic annular preventer
Upper hydraulic annular preventer is opened after seal pressure venting, top universal oil pumping rod slips is opened and unclamps under sucker rod, telescopic oil cylinder
Row turns off upper hydraulic annular preventer to bottom dead centre, closes well head top universal oil pumping rod slips clamping sucker rod, closes two
Only surge Flat Sluice, other elements are all in open mode, up sucker rod of telescopic oil cylinder, sucker rod is prevented with upper hydraulic annular
It is fricton-tight between spray apparatus, belong to static seal, so circulation realizes that blowout prevention with pressure plays sucker rod operation.
(2) lower sucker rod process is similar to playing sucker rod process.
The operation process of lower oil tube of the present invention is as follows：
(1) pipe process is played：Universal oil pumping rod slips clamping oil pipe is closed, top fixed hydraulic slips is opened and unclamps oil pipe,
Close top hydraulic pressure single disc and partly seal preventer, close two Flat Sluices of surging, hydraulic pressure single disc seals preventer, lower hydraulic entirely
Single disc partly seals preventer, bottom fixed hydraulic slips, lower hydraulic annular preventer, middle part hydraulic pressure single disc half and seals preventer all
In open mode, up of telescopic oil cylinder pipe, oil pipe and top hydraulic pressure single disc half seal blowout prevention clamor between to be slidingly sealed, when
When tubing coupling enters balance off-load four-way adapter position, lower hydraulic annular preventer is closed, two Flat Sluices of surging are opened,
The seal pressure that top hydraulic pressure single disc half is sealed between preventer and lower hydraulic annular preventer is discharged, top hydraulic pressure list lock is opened
Plate partly seals preventer, continues up until box cupling exposes well head, oil discharge pipe closes top fixed hydraulic slips clamping oil pipe, beaten
Open top fixed hydraulic slips and unclamp oil pipe, the descending starting point that returns to of telescopic oil cylinder prepares a time pipe, turns off universal oil pumping rod card
Watt clamping oil pipe, open top fixed hydraulic slips and unclamp oil pipe, repeats above-mentioned action and realizes that multiple-tubing string rises.
(2) Tubing During Running is similar to playing Tubing During Running under.
It can carry out lower oil tube with pressure, and energy sucker rod operation with pressure, and the part of replacing should not both move well head,
Lifting appliance is not needed to coordinate, operator scene just can easily be realized.Its novel in structural design, clever structure, thinking is unique,
Security performance and operating efficiency significantly are improved, there is higher economy and promotional value.
