Abstract
The slideway buffering device is applied to the underground workover construction of an oil and gas field to buffer a pipe column. The middle parts of the rectangular front buffer plate and the rectangular rear fixing plate are respectively provided with two rows of through holes, and each row is provided with three through holes; six bolts respectively penetrate through the through holes of the front buffer plate, and are respectively sleeved with a compression spring which is arranged between the front buffer plate and the rear fixing plate; a buffer backing plate is arranged on the upper part of the bolt, and the buffer backing plate and the front buffer plate are opposite and fixed together in parallel. The effect is as follows: the oil pipe makes the impact force of tubular column obtain the buffering at the slide gliding in-process, prevents that the tubular column from dashing out the slide, avoids the tubular column phenomenon of sideslipping, has reduced intensity of labour, has improved the operation security.
Description
Technical field
The utility model relates to the oil-gas field downhole operation technical field, and particularly a kind of servicing unit of lift pipe string in the well workover construction is a kind of slideway buffer.
Background technology
Along with oil field development progressively realizes standardization, standardization, in the construction operation of down-hole, the safety in the operation process more and more receives people's attention.In the underground work process; Lift pipe string is a very heavy operation, and drilling rod, oil pipe, the drill collar impact force on slideway is very big, the time regular meeting drilling rod, oil pipe, drill collar occur and go out slideway; Bring trouble to construction operation, strengthened working strength of workers.
At present; The underground work lift pipe string stretches tight when single; The method that adopts is a bolt wire rope coupling hook pipe on rig floor, and the afterbody that hook is hooked in drilling rod, oil pipe, drill collar glides, or to install the impact that baffle plate stops drilling rod, oil pipe, drill collar additional at the slideway afterbody be that it is parked on the slideway.There are three problems in above way, and the one, hook is thrown off easily in the tubing string downslide process; The 2nd, be prone to the horizontal phenomenon of getting rid of of tubing string takes place, cause casualties, increased the job safety risk; The 3rd, tubing string is gone out slideway and need tubing string be lifted back, strengthens labour intensity; The 4th, adopt dead baffle plate to be prone to cause the damage of tubing string pin thread, baffle plate damages under huge impact.
The utility model content
The purpose of the utility model is: a kind of slideway buffer is provided, can satisfies the tubing string downslide requirement in the well workover lift pipe string process.Prevent that tubing string from going out slideway, reducing labour intensity, effectively protect the tubing string pin thread.
The technical scheme that the utility model adopts is: the slideway buffer; Comprise front buffer plate, rear fixed plate, bolt, compression spring, nut, buffer plate and hold-down screw; It is characterized in that: rectangular front buffer plate and rear fixed plate middle part are respectively to there being two exhausting holes, and every row has three through holes; Six bolts pass the through hole of front buffer plate respectively, are with a compression spring on respectively at bolt, and the end of bolt is passed the through hole of rear fixed plate again; Six compression springs are fixed with nut respectively in the end of bolt in the middle of front buffer plate and rear fixed plate; One block buffering backing plate is arranged on the top of bolt; Buffer plate is rectangular plate; Buffer plate is parallel with front buffer plate relatively; Two ends at buffer plate and front buffer plate have fixing hole respectively, and hold-down screw passes the fixing hole at buffer plate and front buffer plate two ends, and hold-down screw is fixed together buffer plate and front buffer plate.
During use, rear fixed plate is fixed on the slideway afterbody of workover rig with welding manner.Rear fixed plate and ground form 15～30 ° angle.During lift pipe string, on the collision buffering backing plate of tubing string lower end, because buffer plate is fixed on the front buffer plate, front buffer plate is close to the compression spring through bolt, front buffer plate extruding compression spring, and the tubing string impact obtains buffering.
The beneficial effect of the utility model: the utility model slideway buffer, be installed in the slideway afterbody, oil pipe is in slideway slide down process; Receiving when impacting, the compression spring by compression, the tubing string impact obtains buffering; Avoided hard contact, a large amount of impact forces has been decomposed, prevented that tubing string from going out slideway; Avoid the horizontal phenomenon of getting rid of of tubing string, reduced labour intensity, improved operational security.Be applicable to the impact of all kinds of tubing strings, realize the protection of make-up.Simple in structure, easy to use, low price, very easily utilization and extention.
Description of drawings
Fig. 1 is the utility model slideway buffer structural profile sketch map.
Among the figure, the 1-buffer board, the 2-rear fixed plate, the 3-bolt, 4-compresses spring, 5-nut, 6-buffer plate, 7-hold-down screw.
The specific embodiment
Embodiment 1: with a slideway buffer is example, and the utility model is done further explain.
Consult Fig. 1.The utility model slideway buffer comprises front buffer plate 1, rear fixed plate 2, bolt 3, compression spring 4, nut 5, buffer plate 6 and hold-down screw 7.
The length of rectangular front buffer plate 1 and rear fixed plate 2 is respectively 800mm, and width is 450mm.Front buffer plate 1 and rear fixed plate 2 middle parts are respectively to there being two exhausting holes, and it is the through hole of 21mm that every row has three diameters.The bolt 3 of six M20 passes the through hole of front buffer plate 1 respectively, is with a compression spring 4 on respectively at bolt 3, and the end of bolt 3 is passed the through hole of rear fixed plate 2 again.Six compression springs 4 are middle with rear fixed plate 2 at front buffer plate 1, are fixed with the nut 5 of a M20 respectively in the end of bolt 3.On the top of bolt 3 a block buffering backing plate 6 is arranged, buffer plate 6 is rectangular plate, length 700mm, width 45omm.Buffer plate 6 is parallel relative with front buffer plate 1, at the two ends of buffer plate 6 and front buffer plate 1 two fixing holes is arranged respectively.Four hold-down screws 7 pass four fixing holes at buffer plate 6 and front buffer plate 1 two ends, and hold-down screw 7 is fixed together buffer plate 6 and front buffer plate 1.
