Description
Technical Field
The utility model discloses an interior water conservancy diversion formula scale control centralizer that excels in, centralizer equipment technical field.
Background
The oil field oil extraction operation mostly adopts mechanical oil extraction, and the oil pumping machine, the sucker rod and the oil well pump are matched for operation.
The oil pipe forms a pipe column to connect the well head and the pump barrel assembly of the oil well pump, the rod column formed by the oil pumping rod is connected with the oil pumping machine and the plunger assembly of the oil well pump in the pipe column, the oil pumping machine drives the plunger assembly of the oil well pump to reciprocate up and down in the pump barrel assembly of the oil well pump through the rod column to pump well fluid to the ground.
Centralizers are required because the string and the string are constantly rubbing against each other. However, most of the existing centralizers are made of nylon materials, and the wear resistance is extremely poor. Some metal wear-resistant centralizers were developed, however, the overflow holes of the metal centralizers are easy to block after being scaled.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that the existing nylon centralizer is not wear-resistant, and the metal centralizer is easy to be blocked after flowing hole scaling, and provides an inner diversion type high-strength anti-scaling centralizer with an anti-scaling coating in a liquid inlet hole.
The utility model discloses the problem that will solve is realized by following technical scheme:
an internal diversion type high-strength anti-scaling centralizer comprises: the anti-scaling wear-resistant pipe comprises a body, a low-resistance wear-resistant layer and an anti-scaling coating, wherein a large annular table is arranged in the middle of the body, an axial inner diversion hole is formed in the large annular table, the anti-scaling coating is arranged on the inner side of the axial inner diversion hole, and the low-resistance wear-resistant layer is arranged on the outer side of the large annular table.
Preferably, the axial inner diversion hole is provided with a plurality of diversion holes.
Preferably, the outer side of one end of the body is provided with an upper sucker rod connecting thread.
Preferably, the outer side of the other end of the body is provided with a lower sucker rod connecting thread.
Preferably, the anti-scaling coating is made of Teflon or polytetrafluoroethylene.
The utility model discloses for the beneficial effect that has now:
the utility model discloses interior water conservancy diversion hole is provided with the scale control coating, reduces and blocks up. The body adopts the metal material and covers and has low resistance wearing layer, and the whole mechanism is simple scientific more, accords with present design requirement.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, a first embodiment of the present invention provides an internal diversion high-strength anti-scaling centralizer based on the prior art, which comprises: the body 1, the low-resistance wear-resistant layer 2, and the antifouling coating layer 4 will be described in detail one by one below with reference to the connection relationship of the respective components. Firstly, a body 1 is introduced, a large annular platform 5 is arranged in the middle of the body 1, an axial inner flow guide hole 3 is formed in the large annular platform 5, the number of the axial inner flow guide holes 3 is 4, an anti-scale coating 4 is installed on the inner side of each axial inner flow guide hole 3, and a low-resistance wear-resistant layer 2 is installed on the outer side of the large annular platform.
Wherein, for simple to operate, the one end outside of body 1 is equipped with sucker rod connecting thread 6, and the other end outside is equipped with sucker rod connecting thread 7 down, and what antiscale coating 4 was teflon or polytetrafluoroethylene material, and low resistance wearing layer 2 surface abrasive machining is to smooth level and smooth, and hardness is high, wear-resisting drag reduction.
The specific working mode is as follows:
the sucker rods at the two ends of the main body 1 are in threaded connection with the rod string, the low-resistance wear-resistant layer 2 is in contact with the inner hole of the string for centralizing, well fluid flows through the inner diversion hole 3, and the anti-scale coating 4 plays a role in scale prevention.
While embodiments of the invention have been disclosed above, it is not intended to be limited to the applications listed in the specification and the examples. It can be applicable to various and be fit for the utility model discloses a field completely. Additional modifications will readily occur to those skilled in the art. The invention is therefore not to be limited to the specific details and illustrations shown and described herein, without departing from the general concept defined by the claims and their equivalents.
