Abstract
The utility model relates to a guiding and centralizing device for a rod string. The guiding and centralizing device is composed of an upper connector, an upper roller, a connecting tube, a lower roller and a lower connector, wherein threads at the lower part of the upper connector are connected with the upper part of the connecting tube, the lower part of the connecting tube is connected with threads at the upper part of the lower connector, the upper roller is installed at the lower part of the upper connector, and the lower roller is installed at the upper part of the lower connector. The guiding and centralizing device is installed on an oil string of an oil well with a coiled rod used for oil sucking; when being used for sucking oil, the coiled rod is contacted with the upper roller and the lower roller; the upper roller and the lower roller are rotated; and the rolling friction is formed between the coiled rod and the upper roller and between the coiled rod and the lower roller, thereby avoiding the abrasion between the coiled rod and the oil tube.
Description
One, technical field
The utility model belongs to the instrument that the down-hole, oil field prevents the wearing and tearing of oil pipe sucker rod, is a kind of roofbolt guiding erection device.
Two, background technology
In the oil pumping system of oil field, R a T has relative contact movement, certainly existing between sucker rod and the oil pipe and rubbing, the problem of sucker rod partial wear oil pipe occurring, behind the generation eccentric wear oil pipe and sucker rod can not used, cause the oil well operation, oil well repair free period is short, increases operating cost, increases rod tube consumption, the oil well off-time is many, reduces crude output.The normal problem that adopts oil pumping rod centering device to solve oil pipe and sucker rod partial wear on the oil recovery technique.Oil pumping rod centering device can only be connected on the sucker rod, and coiled rod can not add oil pumping rod centering device from the centre, so with the oil well rod tube serious wear of coiled rod oil pumping.
Three, summary of the invention
The purpose of this utility model is a kind of roofbolt guiding of design erection device, and the continuous bar pumpingh well that is applicable to that is installed on the tubing string prevents the wearing and tearing of oil pipe sucker rod.
The purpose of this utility model is achieved in that by top connection, upper roller, connecting tube, bottom roller, lower contact to be formed, the top connection lower thread connects with connecting tube top, connecting tube bottom and lower contact top thread connection, roller is installed in the top connection bottom, and bottom roller is installed on lower contact top.
The beneficial effects of the utility model are: be installed on the oil well oil conduit post with the coiled rod oil pumping, during the coiled rod oil pumping, coiled rod contacts with upper roller, bottom roller, upper roller, bottom roller rotation, coiled rod and upper roller, bottom roller are rolling friction, can avoid the wearing and tearing between coiled rod and the oil pipe.
Four, description of drawings
Accompanying drawing is the utility model embodiment assembling drawing.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.As shown in the figure, top connection 1, upper roller 2, connecting tube 3, bottom roller 4, lower contact 5 are formed, and top connection 1 lower thread connects with connecting tube 3 tops, connecting tube 3 bottoms and lower contact 5 top thread connection, roller 2 is installed in top connection 1 bottom, and bottom roller 4 is installed on lower contact 5 tops.
