Abstract
The utility model discloses an operation well rod string plays clamping device down uses with well head oil pipe hydraulic tong cooperation, plays rod string down in the light maintenance construction operation in the pit, to in the rod string implementation, the operation of breaking out. This clamping device includes regulation gland and barrel, is equipped with the sucker rod and imports and exports on adjusting gland and barrel, and barrel upper portion is the cassette with regulation gland threaded connection, lower part, and adjusting screw's front end and fixture block threaded connection install in the cassette. Need not the sucker rod of breaking out on the manpower, utilize oil pipe hydraulic tong to realize unloading the sucker rod on mechanized through this device, increased oil pipe hydraulic tong's service function and scope, reduced the changeover procedures of well head operation equipment. The efficiency of the operation is improved, the purpose that goes up, unloads the mechanized operation of sucker rod has been reached.
Description
Technical field
The utility model relates to the running and pulling device of petroleum industry well in operation rod string, particularly well in operation rod string removes clamping device, with well mouth oil pipe hydraulic tongs with the use of, actuating oil-pumping unit post in down-hole light maintenance construction operation, upper, shackle operation is implemented to rod string.
Background technology
Rod job refer to the original sucker rod in well in operation all tripped out or completion time enter in oil well to resume production by under the sucker rod of certain length.General in the well in operation of dark 2000 meters of pump, the quantity of sucker rod is at about 200.Although current rod job has sucker rod to remove dedicated hydraulic pincers, due to its clamping body complex structure, the reason such as slip insert clamping force is too little, slip insert is easy to wear, the rountrip of sucker rod can not be met.Rod job, artificial upper, the shackle of main or dependence.During operation, two people bite lower contact on sucker rod with pipe wrench simultaneously, and pure manpower dismantles the sucker rod of connection round about, and sucker rod rountrip belongs to very loaded down with trivial details and tired construction operation.At present, there is following drawback in artificial rod job:
1, labour intensity is very big, operating worker fatiguability, and human body overwork easily produces actual bodily harm.
The phenomenons such as the sucker rod burn into 2, be in for a long time in production is adhered, fusion are serious, and its bonding strength is large, and pure manpower shackle is very difficult, often occur the situation that full teams and groups personnel take turns going to battle.Dismantling a sucker rod takes long, greatly reduces operation timeliness.
3, the working continuously of high strength, constructor is extremely tired, and often there will be again pipe wrench and sting and loosely skid, construction plant is little, ground by a variety of causes affect exist wet and slippery, the situation such as be uneven, very easily there is pipe wrench and rebound, collide, the injury accident such as to fall down.
Summary of the invention
The purpose of this utility model is to provide well in operation rod string and removes clamping device, with well mouth oil pipe hydraulic tongs with the use of, for removing of well in operation rod string provides operation simple, safety, efficiently construction equipment.Avoid the high cycle fatigue of constructor in rod job, accelerating construction progress, improve the safety of construction.
Technical solution of the present utility model is:
Well in operation rod string removes clamping device and comprises adjustment gland and cylindrical shell, adjustment gland and cylindrical shell are provided with sucker rod import and export, gland is threaded, bottom is deck for cylindrical shell top and adjustment, and the front end of adjusting screw(rod) is threaded with fixture block, is arranged in deck.This device is fixed in the jaw of oil tube hydraulic tong, uses on oil tube hydraulic tong, unloads rod string, not only can above, unload sucker rod, also can above, unload rod collar.
The width that sucker rod on described adjustment gland and cylindrical shell is imported and exported is set between 19mm-36mm.
The middle part of described cylindrical shell is hydraulic tongs embedded body, and the external diameter of hydraulic tongs embedded body conforms to the internal diameter of hydraulic tongs jaw, height conforms to the height of hydraulic tongs jaw.
Fixture block is square block, and front end surface is that plane coordinates with the square rib of sucker rod upper step.
Compared with prior art, remarkable result of the present utility model is: without the need to shackle sucker rod on manpower, utilize oil tube hydraulic tong to realize sucker rod is unloaded in mechanization by this device, add using function and the scope of oil tube hydraulic tong, decrease the replacing program of shaft mouth operation equipment.Improve operating efficiency, reach, unload the object of sucker rod mechanized operation.Its major advantage is:
1, eliminate manually and unload sucker rod, realize do mechanization operation, greatly reduce the labour intensity of constructor, accelerate construction speed, improve construction operation safety.
2, substantially increase operation timeliness, the speed of above unloading sucker rod is more than the twice of manual work speed.
3, while reducing constructor's labour intensity, job safety has well been ensured.Revolutionize the mode using pipe wrench manual work, eliminate the potential safety hazards such as pipe wrench rebounds, personnel slip, collide with.
4, this apparatus structure is simple, easy to manufacture, convenient to operation.With the square rib of two fixture block clamping sucker rod upper step, fixture block is not fragile, not easy to wear, indeformable, and clamping force is large, even if it is also simple and convenient to damage its repair and replacement, completely eliminates the familiar lacunas of sucker rod dedicated hydraulic pincers.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing in detail the utility model is described in detail, see Fig. 1, well in operation rod string removes clamping device and comprises adjustment gland 1 and cylindrical shell 3, adjustment gland 1 and cylindrical shell 3 are provided with sucker rod and import and export 7, gland 1 is threaded, bottom is deck 5 for cylindrical shell 3 top and adjustment, the front end of adjusting screw(rod) 4 is threaded with fixture block 6, is arranged in deck 5.The width regulating the sucker rod on gland 1 and cylindrical shell 3 to import and export 7 is set between 19mm-36mm, is applicable to various rod string.The middle part of cylindrical shell 3 is hydraulic tongs embedded bodies, and the external diameter of hydraulic tongs embedded body conforms to the internal diameter of hydraulic tongs jaw, height conforms to the height of hydraulic tongs jaw, can by regulating gland 1 to regulate with the engagement height of hydraulic tongs jaw.Fixture block 6 is square blocks, and front end surface is that plane coordinates with the square rib of sucker rod upper step.Because fixture block 6 is seizing on the square rib of sucker rod upper step, its clamping force greatly, not easy to wear, structure is simple, easy to adjust.Regulate the both sides of gland 1 to be provided with fixed-wing 2, be bolted on Hubei Province plate of hydraulic tongs.Also can by strengthening the radial dimension and thickness that regulate gland 1 if do not arrange fixed-wing 2, in its shell wall, machining shaft is to bolt hole, is fixed on Hubei Province plate of hydraulic tongs by adjustment gland 1 by bolt.
The using method of this device is:
1, be installed on by this device in the main pincers jaw of oil tube hydraulic tong, its sucker rod is imported and exported 7 and is alignd with the main jaw of hydraulic tongs, and by fastening good for two fixed-wings 2.
2, the slip insert sheet of clamping rod collar is installed in back-up tong.
3, adjust the height of the main pincers of hydraulic tongs, use fixture block 6 to sting the square rib of tight sucker rod upper step, back-up tong stings tight rod collar.
4, adjust hydraulic tongs reversing pin, make main pincers and back-up tong all be in shackle position.
5, operate hydraulic tongs and carry out operation that is upper, that unload sucker rod.
