Abstract
The utility model relates to a drop and wear preventing centralizer, which is composed of a lower joint 1, a cushion chamber 2, an upper joint 3 and a spring 4. Because the utility model adopts the upper joint and the cushion chamber, the T-shaped lower joint is arranged in the cushion chamber and extends out, the spring is wound on the T-shaped lower joint and is installed on a sucker rod, shock is absorbed by the spring, the sucker rod can not be easily bent under the conditions of alternate loads, the eccentric wear and the parting of the sucker rod are prevented, the pump inspection period of an oil well is extended, the production cost is reduced and the design is reasonable and simple.
Description
Technical field:
The utility model relates to the downhole tool that uses on a kind of oilfield, particularly a kind of prevent dropping off and wearing off centralizer.
Background technology:
In field produces, it is very general that the leakage of sucker rod partial wear and oil pipe takes place, this is because the oil well oil-pumping number of times speeds, upstroke and pump generation fluctuating load when descending, at sucker rod certain is a bit bumped, cause rod sag, take place that sucker rod partial wear is disconnected to be taken off, influence the production of oil well, increased operating cost.
Technical scheme
The utility model purpose is to provide a kind of prevent dropping off and wearing off centralizer, and it can effectively solve, and sucker rod partial wear is disconnected to be taken off, and prolongs the pump detection period of oil well, has reduced cost of production.
The utility model purpose is to realize like this, it is made up of lower contact (1), cushion chamber (2), top connection (3), spring (4), top connection (3) is connected with cushion chamber (2), has T type lower contact (1) to stretch out in cushion chamber (2), goes up winding spring (4) in T type lower contact (1).
The utility model is owing to adopted top connection to be connected with cushion chamber, in cushion chamber, there is the lower contact of T type to stretch out, winding spring in the lower contact of T type, it is installed on the sucker rod, by spring shock absorption, not flexible at the fluctuating load lower sucker rod, thus preventing that sucker rod partial wear is disconnected takes off, prolong the pump detection period of oil well, reduced cost of production.It is reasonable in design, simple, is well suited for applying.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in the figure, the utility model is made up of lower contact 1, cushion chamber 2, top connection 3, spring 4, and top connection 3 is connected with cushion chamber 2, has T type lower contact 1 to stretch out in cushion chamber 2, winding spring 4 in the lower contact 1 of T type.It is installed on the sucker rod, pass through spring shock absorption, not flexible at the fluctuating load lower sucker rod, thereby preventing that sucker rod partial wear is disconnected takes off, particularly be suitable for super viscous crude, high coagulate oil, take out well, horizontal well deeply, increase the production per cycle of oil well, prolonged the pump detection period of oil well, reduced cost of production.
Claims (1)
1, a kind of prevent dropping off and wearing off centralizer, it is made up of lower contact (1), cushion chamber (2), top connection (3), spring (4), it is characterized in that: top connection (3) is connected with cushion chamber (2), has T type lower contact (1) to stretch out in cushion chamber (2), goes up winding spring (4) in T type lower contact (1).
