Abstract
The adjustable polished rod centering device is applied to polished rod centering when a wellhead of an oil well is replaced by an O-shaped sealing packing. The clamp mainly comprises a clamp base, a support rod, a nut, a screw rod and an arc-shaped top block, wherein the support rod is axially welded on the outer wall of the clamp base, the nut is horizontally welded at the top end of the support rod, the screw rod is arranged in the nut, and the arc-shaped top block is arranged at the end part of the screw rod. The arc kicking block include the arc steel sheet, the welding has a cylinder on the outer wall of arc steel sheet, has the taper hole at the other end of cylinder, the screw rod tip can insert in the taper hole. The effect is as follows: the polished rod can be centered, and the original manual operation method is thoroughly changed. The potential safety hazard in the operation process is eliminated. The safe, convenient, simple and quick operation is achieved.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of polished rod of oil well oil-pumping well head is a kind of polished rod centering special tool when changing well mouth of oil well " O " type sealed packing.
Background technology
In field produces, the diameter that generally adopts polished rod is 1.2 inches, and the internal diameter of well head is 2.5 inches, and polished rod is done in well head and pumped, and seals with " O " type rubber packing.The part oil well causes polished rod center and well head packing box misalignment owing to reasons such as production time length, oil well operation, foundation deformations, operating difficulties when changing packing.At least need two people, a people to push away the positive center of polished rod at well head when changing packing, a people changes " O " type rubber packing_seal in the well head packing seal box, and the operating time is long at every turn.
1. the operating time needs 40 minutes at least when changing packing at every turn, and the operating time is long.
2. need two people operation at every turn when changing packing at least, cause the waste of manpower.
3. because polished rod and well head misalign, cause operating difficulties when changing packing, the employee is with the not positive polished rod of pipe wrench in the operating process.So both damage well head packing box screw thread easily, had great potential safety hazard (the pipe wrench slippage is pounded and hurted sb.'s feelings) again.
4. because long meeting of operating time influence the production of oil well, reduce the oil production of crude oil, can cause oil well Ka Jing when serious.
5. increased operative employee's labour intensity.
Only at polished rod during at well head packing box center, packing could very light replacing.
The utility model content
The purpose of this utility model is: a kind of adjustable optical bar centralizer is provided, makes polished rod and well head packing seal box reach accurate centering.Change lacquer disk(-sc) root safety, quick.
The technical solution adopted in the utility model is: adjustable optical bar centralizer, mainly form by clip base, support bar, nut, screw rod and arc jacking block, it is characterized in that: on the outer wall of clip base, axially be welded with a support bar, be connected to nut in the horizontal welding of the top of support bar, a screw rod is arranged in nut, and there is an arc jacking block end of screw rod.Described arc jacking block comprises curved plate, is welded with a cylinder on the outer wall of curved plate, at the cylindrical other end taper hole is arranged, and the screw rod end can be inserted in the taper hole.When the inner arc surface of arc jacking block being put on the outer wall of polished rod, the screw rod end can be inserted in the taper hole and rotating screw bolt, can move to the center of well head packing box by polish rod, and can remain on the center of well head packing box.Easier, change " O " type rubber packing in the packing box easily.
Easier in order to operate, at spiro rod rear end through hole is arranged, shaft-like rocking handle is arranged in through hole.
Described clip base is made up of two blocks of semicircle steel plates and bolt, the two ends of semicircle steel plate are connected with plain plate, bolt hole is arranged on plain plate, two back relatively outer walls of semicircle steel plates are approximate circle cylinder shape, the plain plate that two ends connect is parallel to each other, vertical distance between the plain plate that two ends connect is 5～10 millimeters, and bolt passes the bolt hole on the plain plate and two blocks of semicircle steel plates are fixed.
The using method of summary adjustable optical bar centralizer: consult Fig. 1.Clip base 3 is installed on the well head packing box 2, and clip base 3 can be done 360 degree rotations around well head packing box 2, makes the direction of jackscrew consistent with the direction of polished rod deflection, and is by bolt that clip base 3 is fixing.Arc jacking block 8 is put between polished rod 1 outer wall and screw rod 6 tops; Rotation rocking handle 7, screw rod 6 is pushed ahead, and polish rod 1 arrives well head packing box 2 centers.Just can change packing easily.
The beneficial effects of the utility model: the utility model adjustable optical bar centralizer, can make polished rod centering, thoroughly changed original only by the manual operation method.Each when changing the packing operation by original two people operation, reduce to present people's operation, reduced labour intensity, and the operating time dropped to present each 10 minutes by original each 40 minutes, eliminated the potential safety hazard in the operating process.Reached operation safe, convenient, simple and fast.
Description of drawings
