Abstract
The utility model discloses a kind of decentralized wellhead centralizer, it is characterized in that: it comprises power bar, the clamping device for clamping packing box is fixedly installed in the lower end of power bar, the upper end of power bar is provided with rotation push rod, described rotation push rod is vertical with power bar to be arranged, and in the screwed hole on the power that the is installed on bar of described rotation push rod, its one end is provided with handle, the other end is provided with thrust block pad, for polish rod.The utility model can be easy and convenient replacing packing, reduce the labour intensity of workman, reduce and stop the economic loss that well causes for a long time, there is structure simple, easy for installation, the feature such as safe and reliable.
Description
Technical field
The utility model relates to a kind of decentralized wellhead centralizer.
Background technology
Beam pumping unit well is a kind of capital equipment in field produces, and beam pumping unit well accounts for more than 95% of machine-pumped oil well.Part oil pumper, because the reason such as thermal recovery, operation, causes wellhead packing box and polished rod to misalign.Because well head is inclined, when changing packing, taking out old packing, to add new packing all very difficult, not only wastes time and energy, and rate when also reducing the oil recovery of rod-pumped well, adds the labour intensity of post workman, bring certain economic loss to field produces.
At present, packing difficulty is changed in the inconvenience maximum in production management of beam pumping unit well decentralized wellhead exactly, and the frequency changing packing is higher, in order to alleviate the labour intensity of workman, reduce because of the economic loss brought that stops production, for this situation, have developed well head centralizer.
Utility model content
Technical problem to be solved in the utility model is that the deficiency existed for above-mentioned prior art provides the decentralized wellhead centralizer that a kind of structure is simple, be convenient for changing packing.
The technical scheme that the utility model adopts is: a kind of decentralized wellhead centralizer, it is characterized in that: it comprises power bar, the clamping device for clamping packing box is fixedly installed in the lower end of power bar, the upper end of power bar is provided with rotation push rod, described rotation push rod is vertical with power bar to be arranged, and in the screwed hole on the power that the is installed on bar of described rotation push rod, its one end is provided with handle, the other end is provided with thrust block pad, for polish rod.
By technique scheme, described clamping device comprises keeper, holder, and described keeper is fixedly installed on the lower end of power bar, after one end of described holder and keeper one end are hinged, is connected after the other end walks around packing box with the other end of keeper.
By technique scheme, described keeper is angle bar, and holder is knee.
By technique scheme, the other end of knee is provided with screw thread, is fastened by bolts after the draw-in groove that this end spiral-lock is arranged on the positioning element.
By technique scheme, the vertical direction along keeper is arranged at intervals with multiple holder.
By technique scheme, the inwall of thrust block pad is arc-shaped or rectangular-shaped.
The features such as the beneficial effect acquired by the utility model is: the replacing packing that the utility model can be easy and convenient, reduces the labour intensity of workman, reduces the economic loss of stopping well for a long time and causing, has structure simple, easy for installation, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the decentralized wellhead centralizer that the present embodiment provides, it comprises power bar 3, is fixedly installed the clamping device for clamping packing box in the lower end of power bar 3, is provided with rotates push rod 2 in the upper end of power bar 3, rotate that push rod 2 is vertical with power bar 3 arranges, rotating push rod 2 is installed in the screwed hole on power bar, and its one end is provided with handle, and the other end is provided with the thrust block pad 1 of arc-shaped, for matching with polished rod 8, polish rod 8.
In the present embodiment, described clamping device comprises keeper 4, each and every one holder 5 of vertical direction spaced two along keeper 4, described keeper 4 is fixedly installed on the lower end of power bar 3, after one end of described holder 5 and keeper 4 one end are hinged, be connected with the other end of keeper 4 after the other end walks around packing box 7.
In the present embodiment, described keeper 4 is angle bar, and holder 5 is knee.The other end of knee is provided with screw thread, is fastened by bolts after the draw-in groove 6 that this end spiral-lock is arranged on the positioning element.Wherein, the inwall of thrust block pad 1 is arc-shaped or rectangular-shaped (in figure be rectangular-shaped be described for thrust block pad), is convenient to coordinate with polished rod.
Claims (5)
