CN205532363U - Sleeve pipe centralizer of a body structure - Google Patents

Abstract

The utility model relates to a sleeve pipe centralizer of a body structure, the installation structure comprises a sleeve, upper fixed ring, mark closely, the centralizer body, lower fixing ring, the spring steel sheet material quality of its characterized in that centralizer body structure as an organic whole, this is provided with the sleeve pipe internal running through the centralizer, the top of centralizer body is provided with upper fixed ring, the bottom of centralizer body is provided with lower fixing ring, upper fixed ring and lower fixing ring all fix in the sheathed tube outside through marking closely, upper fixed ring and lower fixing ring fix the centralizer body in the sheathed tube outside, upper fixed ring and lower fixing ring are formed by 45# steel tube machining. The beneficial effects of the utility model are that, the centralizer body that adopts the spring steel sheet to form has high strength, unstressed weak spot, advantage that the reliability is high, and the centralizer body does not have any separable set, and the in -process is gone into under to the risk of having avoided spare part to come off, and factor of safety improves greatly.

Description

The casing stabbing board of integrative-structure

Technical field

This utility model technology belongs to petroleum industry field, is mainly used in horizontal well, high angle hole casing centering, particularly says it is the casing stabbing board of a kind of integrative-structure.

Background technology

Currently used common elastic centralizer and rigid centralizer, shortcoming enters difficulty under being, support force is not enough, it is impossible to play good righting effect, and owing to building block is more, under enter during, easily cause element falling, cause serious accident.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the casing stabbing board of a kind of integrative-structure is provided, this utility model solves its technical problem and be the technical scheme is that structure of the present utility model includes sleeve pipe, upper retainer ring, mark closely, centralizer body, lower retainer ring, it is characterized in that the steel spring plate material that centralizer body is structure as a whole, sleeve pipe it is provided through in centralizer body, the top of centralizer body is provided with retainer ring, the bottom of centralizer body is provided with lower retainer ring, upper retainer ring and lower retainer ring are all by marking closely the outside being fixed on sleeve pipe, centralizer body is fixed on the outside of sleeve pipe by upper retainer ring and lower retainer ring, upper retainer ring and lower retainer ring are processed by 45# steel pipe.

The beneficial effects of the utility model are, the centralizer body using steel spring plate composition has high intensity, unstressed weak spot, advantage that reliability is high, centralizer body is without any separation assembly, it is to avoid the risk that parts come off, during entering under, safety coefficient is greatly improved.
