Abstract
Body is right to coupling spiral (b) is (b) an oil field oil recovery technique, and it has overcome the shortcoming of other centralizers, it be right the body, spout the nickel alloy layer, sucker rod, spiral oil flow groove be formed by connecting, it is as an organic whole with the sucker rod to right the body, rights the position directly over sucker rod collar, the coupling is right body overall length and is 50mm, and the external diameter is 58mm, with oil pipe's internal diameter phase -match, spout wear -resisting high temperature resistance nickel alloy layer on three bellied cambered surfaces of the body are right to the coupling, the nickel alloy layer accounts for rights body surface area's 50%, and the nickel alloy layer thickness is 0.5mm, be provided with three helicla flute on right the body.
Description
Technical field:
The utility model relates to oil extraction in oil field technology, especially box cupling spiral centralizer body.
Background technology:
The centralizer being applied to oil extraction in oil field is at present varied, and due to the difference of structure, effect is also different.
Summary of the invention:
The purpose of this utility model is to provide a kind of wear-resisting, resistant to elevated temperatures box cupling spiral centralizer body, which overcome the shortcoming of other centralizer, the purpose of this utility model realizes like this, it is formed by connecting by centralizer body, spray nickel alloy layer, sucker rod, spiral flow oil groove, centralizer body and sucker rod are integrated, and centralizer body is positioned at directly over rod collar.
Described box cupling centralizer body, its overall length is 50mm, and external diameter is 58mm, matches with the internal diameter of oil pipe.
Described box cupling centralizer body, three cambered surfaces of its projection are sprayed the nickel alloy layer of Wear-resistant, high-temperature resistant, and nickel alloy layer accounts for 50% of centralizer body surface area, and nickel alloy layer thickness is 0.5mm.
Described box cupling centralizer body, is provided with three helicla flutes in the above.
Meaning of the present utility model: one is that box cupling adds righting integration, and both met box cupling functional performance, righting effect is again good; Two is that improve the hardness of product, product is wear-resisting, corrosion-resistant, economy and durability due to spray nickel alloy layer; Three is easy to use, eliminates the program of installing separately centralizer; Solve the problem that original nylon centralising device is easy to block; On centralizer body, be provided with three helicla flutes, ensure that crude oil is unimpeded, the wax layer of tube inner wall can be scraped off simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of box cupling spiral centralizer body, in figure 1, box cupling centralizer body 2, nickel alloy layer 3, sucker rod 4, helicla flute
Detailed description of the invention:
Embodiment 1, the utility model are formed by connecting by box cupling centralizer body 1, nickel alloy layer 2, sucker rod 3, helicla flute 4, and box cupling centralizer body 1 and sucker rod 3 are integrated, and box cupling centralizer body 1 is positioned at the centre of sucker rod 3.
Embodiment 2, described box cupling centralizer body 1, its overall length is 50mm, and external diameter is 58mm, adapts with sucker rod 3.
Embodiment 3, described box cupling centralizer body 1, three cambered surfaces of its projection are sprayed the nickel alloy layer 2 of Wear-resistant, high-temperature resistant, and nickel alloy layer 2 accounts for 50% of centralizer body surface area, and nickel alloy layer 2 thickness is 0.5mm.
Embodiment 4, described box cupling centralizer body 1, be provided with three helicla flutes 4 in the above, ensures that crude oil is smooth.
