Description

Centralizer

Technical Field

The utility model relates to a along with boring inclinometer technical field, specific field is along with boring centralizer for inclinometer.

Background

The centralizer is an underground connecting component of an MWD wireless inclinometer, and is used for effectively connecting each core part of the instrument (conducting signals and supplying power to the instrument) and simultaneously enabling the rubber wing part to be in soft contact with a well wall; plays the roles of righting and axial shock absorption. The installation mode of the prior centralizer is as follows: the semi-circular retaining rings at two ends are pressed by pressure of the pressure spring (the semi-circular retaining rings are of a step structure), so that the end head of the centralizer and the rubber wing are prevented from being separated from the centralizer base body. Because the mud in the well has large sand content and high pressure. Therefore, the compressed spring is exposed to the slurry portion, and a vortex is easily formed. The compression spring is broken by impact, and the centralizer matrix can be eroded after a long time. Increasing the cost of the instrument.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a centralizer to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a centralizer, is including righting the pole, the both ends of righting the pole all are connected with the connector, the end has been cup jointed on the connector, install on the end and keep off the ring, keep off and be equipped with the slot on the ring, the middle part of righting the pole has cup jointed the wing.

Preferably, the glue wing is a 4-wing glue wing, and in order to get rid of a stepped semicircular baffle ring pressed by an original pressure spring, a baffle ring with a groove is adopted. The end head and the rubber wing of the centralizer can not fall off.

Preferably, the outer side wall of the end head is provided with an external thread.

Preferably, the connector is provided with a connecting slot.

Preferably, the baffle ring is a semicircular baffle ring.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a centralizer, the utility model discloses replaced original centralizer assembly form complicated relatively. The operation is extremely simple. The utility model discloses no longer use the pressure spring that exposes in mud, right six wings simultaneously and change four wings into and right, make mud flow more smoothly. Vortex is not easy to form; the damage to the adhesive wing and the base body is reduced. The use cost is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a centralizer, is including righting pole 1, the both ends of righting pole 1 all are connected with connector 2, the end 3 has been cup jointed on the connector 2, install on the end 3 and keep off ring 4, keep off and be equipped with the slot on the ring 4, the middle part of righting pole 1 has cup jointed wing 5.

Specifically, the airfoil 5 is a 4-wing airfoil.

Specifically, the outer side wall of the end head 3 is provided with an external thread.

Specifically, the connecting head 2 is provided with a connecting slot 6.

Specifically, the baffle ring 4 is a semicircular baffle ring.

The working principle is as follows: the utility model discloses, can make through 4 wings the utility model discloses near mud flow when using is more smooth and easy, can not drop through keeping off end 3 and the wing 5 that ring 4 enabled the centralizer.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship.
