Abstract
A lead-buckle clamp which can connect the buckles and effectively prevent sticky-buckle between the oil and sleeve pipe during the down-hole process of the oil pipe and the sleeve pipe comprises a cam rack 1, a cam 2, and the like, wherein the handle is integrated with the cam 2 which is connected with the cam rack 1, and the two ends of the cam rack 1 are connected with the hasten-belt 3, further the other end of the hasten-belt 3 is connected with the connection clamp 4. The utility model is labor saving, convenient to operate and reliable in performance (the gross weight is 1.5 kilograms). When in use, the lead-buckle clamp takes only approximately 20 seconds to lead the buckling 3 circles, besides, the lead-buckle clamp can effectively prevent the mistakes of mistaken-buckle and sticky-buckle between the oil and sleeve pipe.
Description
The utility model relates to go into the well make-up in the process of oil pipe in the oil exploitation, sleeve pipe and connects a kind of threading-releasing tong of effectively grease proofing in advance, sleeve pipe thread gluing.
In recent years, a lot of oil, sleeve pipe thread gluing accident have taken place in the oil field, home and abroad, the one of the main reasons that causes oil, the sleeve pipe thread gluing make-up deflection that is the oil field in oil, sleeve pipe are gone into the well process and do not draw and buckle, and directly tightly go up due to the button with the hydraulic tongs machine.Button speed low grade is 40～60 rev/mins on the used most of hydraulic tongs in present domestic oil field, and top grade is 90～110 rev/mins.Used oil, the sleeve pipe in domestic oil field is mainly API round thread oil, sleeve pipe.API round thread oil, sleeve pipe this as fine thread, this kind oil, sleeve pipe are gone into the well when connecting, the internal and external screw thread joint must align and with hand-tight 3～5 circles, and then tightly upward detains with the hydraulic tongs machine.Otherwise be easy to take place thread alternating and thread gluing accident.Actual oil, the sleeve pipe process of going into the well will be subjected to the influence of various factors such as weather, status of equipment, operator quality, are difficult to guarantee oil, sleeve pipe internal and external screw thread joint make-up fully with one heart in the process of going into the well, finally also will be by manually setting upright make-up, drawing button.At make-up, draw that if the internal and external screw thread joint blocks in the button process, rotate with staff this moment will be more difficult.On the other hand, every mouthful of well will descend hundreds of root oil, sleeve pipe, if there is not special use to draw the button instrument, change 3～5 circles to hundreds of root oil, sleeve pipe with every of staff, and operation is wasted time and energy, and almost can not realize fully.With every casing length is 10 meters calculating, and 3000 meters well just need be lowered to 300 sleeve pipes flatly.If the 139.7mm sleeve pipe of small-sized can also rotate with staff.But for the large scale sleeve pipe, for example 177.8mm, 244.5mm, 273.1mm, 339.7mm, 508mm sleeve pipe, rotating with staff will be more and more difficult.Owing to there is not the special-purpose button instrument that draws, at present oil field operator in oil, sleeve pipe process down have to save draw the button operation and directly with the hydraulic tongs machine tight on button, cause taking place oil, sleeve pipe thread gluing accident.
The purpose of this utility model is to provide a kind of generation of avoiding thread alternating and thread gluing accident, thus effectively solve oil, sleeve pipe in the process of going into the well make-up and draw the button problem, the threading-releasing tong of a kind of effectively grease proofing in advance, the sleeve pipe thread gluing of guaranteeing that oil, casing safety go into the well
The utility model comprises cam holder 1, cam 2, adds taut band 3, engages clamp 4 and handle 5, and handle 5 connects as one with cam 2, and cam 2 is connected with cam holder 1, cam holder 1 two ends respectively with add taut band 3 and be connected, add taut band 3 other ends and be connected with joint clamp 4.
Advantage of the present utility model is: easy to operate, laborsaving, and dependable performance (gross weight 1.5kg).Use this threading-releasing tong that a sleeve pipe is drawn button 3 circles and approximately only need 20 second time.Use this threading-releasing tong can prevent effectively that oil, sleeve pipe thread alternating and thread gluing accident from taking place.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further;
This threading-releasing tong has been used mechanical drive principle and lever principle, is fixed on oil, the sleeve pipe as long as will add taut band 3 during use, and buckles and engage clamp 4, moves handle 5 just clamping oil, sleeve pipe at an easy rate, in the realization, the shackle rotating operation.
Engage clamp and can regulate the length that adds taut band arbitrarily.
Be fixed on oil, the sleeve pipe 6 as long as will add taut band 3 during use, and buckle and engage clamp 4, turning handle 5 drives cams 2 in cam holder 1 relative motion, and threading-releasing tong is clamping oil, sleeve pipe 6 at an easy rate just, clockwise rotates, and detains in realizations and operates; Rotate counterclockwise, realize the shackle operation.
