Abstract
The utility model relates to a kind of pumping unit oil well oil recovery technique field, particularly a kind of oil well polished rod clamp pulling force tuner.This device is made up of hollow jackscrew and nut, and the polished rod between polished rod main card I and polished rod main card II installs hollow jackscrew, threaded coupling nut on hollow jackscrew.The utility model achieves can allocate the pulling force size of two polished rod main card to polished rod artificially, make above clamp to polished rod pulling force be greater than below clamp to polished rod pulling force, thus the maximum injury tired end face of card tooth to polished rod is transferred to clamp root above, realize root polished rod at the bottom of clamp above and reach pulling force fatigue limit value at first, when there is brisement, clamp continues to play a role below, eliminates safe hidden trouble.Overcome the deficiency that existing pumping well polish rod often can occur in a polished rod main card end root place tensile phenomenon below in two polished rod main card.
Description
Technical field:
The utility model relates to a kind of pumping unit oil well oil recovery technique field, particularly a kind of oil well polished rod clamp pulling force tuner.
Background technology:
At present, along with increasing the weight of further of oil well polished rod load, pumping well polish rod often can occur in a polished rod main card end root place tensile phenomenon below in two polished rod main card, causes following problem:
One is that oil well stopping production output reduces, and the problems such as oil pumper dallies, belt burns, motor overload occur.Two is that polished rod is fallen in well, causes well head oil spout, causes environment pollution, or unexpected breaking out of fire, even toxic and harmful (H can occur
2s, CO, CO
2) occurred events of public safety such as significant damage such as leakage grade, therefore enterprise will suffer heavy economic losses.Three be artificial again on put forward or change polished rod life period hysteresis quality, oil well can be fought, heat is washed, examine the problems such as pump, this not only adds oil field workman's work load, and adds oil recovery cost of production, thus reduce oil recovery productivity effect.
Occur two polished rod main cards that the basic reason of the problems referred to above is that nature folds installation exist the pulling force of a clamp to polished rod be below greater than above clamp to the pulling force of polished rod, or clamp is zero to polished rod pulling force above, cause root polished rod at the bottom of clamp below to reach pulling force fatigue limit value at first, brisement occurs.The potential safety hazard of above series of problems and existence does not still have a kind of new technology to solve so far.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of oil well polished rod clamp pulling force tuner, the arrangement achieves and can allocate the pulling force size of two polished rod main card to polished rod artificially, make above clamp to polished rod pulling force be greater than below clamp to polished rod pulling force, thus the maximum injury tired end face of card tooth to polished rod is transferred to clamp root above, realize root polished rod at the bottom of clamp above and reach pulling force fatigue limit value at first, when there is brisement, clamp continues to play a role below, eliminates safe hidden trouble.Overcome the deficiency that existing pumping well polish rod often can occur in a polished rod main card end root place tensile phenomenon below in two polished rod main card.
Technical solution adopted in the utility model is: a kind of oil well polished rod clamp pulling force tuner, is made up of hollow jackscrew and nut; Polished rod between polished rod main card I and polished rod main card II installs hollow jackscrew, threaded coupling nut on hollow jackscrew.
The beneficial effects of the utility model are: the utility model can allocate the pulling force size of two polished rod main card to polished rod artificially, make above clamp to polished rod pulling force be greater than below clamp to polished rod pulling force, thus the maximum injury tired end face of card tooth to polished rod is transferred to clamp root above, realize root polished rod at the bottom of clamp above and reach pulling force fatigue limit value at first, when there is brisement, clamp continues to play a role below, eliminates safe hidden trouble.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of oil well polished rod clamp pulling force tuner, is made up of hollow jackscrew 2 and nut 8; Polished rod 6 between polished rod main card I 1 and polished rod main card II 3 installs hollow jackscrew 2, threaded coupling nut 8 on hollow jackscrew 2.In figure, polished rod main card II 3 lower ends are beam hanger for pumping machine 7, and polished rod 6 is provided with the standby clamp 4 of unloading, polished rod 6 lower end is provided with oil-well packing box 5.
During use, be greater than 9 kilogram-metre moments of torsion to hollow jackscrew 2,8 one, nut, polished rod main card I 1 and polished rod main card II 3 held out against, gets off the brakes, allow beam hanger for pumping machine again hanging load run.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
