Abstract
The utility model relates to a petroleum industrial plant, in particular to a novel casing centralizer. The technical scheme of the casing centralizer is characterized in that: the casing centralizer mainly consists of a main body, ball casings, and balls; the outer wall of the main body consists of a plurality of support racks and a flow guide groove to form an integral structure; and the support rack is provided thereon with one or more ball casings, which are installed therein with balls. The casing centralizer provided by the utility model has the benefits that: with the addition of the balls, the casing centralizer has no secondary damage to the tube wall, can accurately ensure the perpendicularity of the casing, improves the axial and radial flexibilities, and avoids the tube wall scratch of the surface casing and the reduction of service life of the casing.
Description
Technical field
The utility model relates to a kind of petroleum industry equipment, particularly a kind of new casing centralizer.
Background technology
At present, when the existing casing stabbing board in oil field is used to go into the well sleeve pipe is set upright, otherwise; The verticality of sleeve pipe is not enough, causes recovering the oil or following oil pipe, blocks oil pipe; Scratch for the tube wall of surperficial sleeve pipe; Even causing the secondary injury, the consequence that causes is to reduce the useful life of surface pipe, has increased the cost for oil production of oil well.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of new casing centralizer is provided, and can not cause the secondary injury to tube wall, can guarantee the verticality of sleeve pipe accurately.
Its technical scheme is: mainly be made up of parent, ball cover, ball, the outer wall of described parent is formed integrative-structure by a plurality of bracing frames and guiding gutter, and described bracing frame is provided with one or more ball cover, in the ball cover, ball is installed respectively.
Above-mentioned guiding gutter adopts linear structure or helical structure.
The beneficial effect of the utility model is: after having increased ball; Can not cause the secondary injury, can guarantee the verticality of sleeve pipe accurately, strengthen axially and flexibility radially tube wall; The tube wall of avoiding reducing surface pipe scratches, and has avoided the reduction of the useful life of sleeve pipe.
Description of drawings
Accompanying drawing 1 is the vertical view of the utility model;
Accompanying drawing 2 is side sectional views of the utility model;
Among the last figure: parent 1, ball cover 2, ball 3, bracing frame 1.1, guiding gutter 1.2.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-2, the utility model is done further to describe: the utility model mainly is made up of parent 1, ball cover 2, ball 3, and the outer wall of described parent 1 is formed integrative-structure by a plurality of bracing frames 1.1 with guiding gutter 1.2; Described bracing frame 1.1 is provided with three ball covers 2, in ball cover 2, a ball 3 is installed respectively, certainly; The ball cover will wrap most ball; Ball can be rolled, in addition, adopt linear structure according to user's needs guiding gutter 1.2.
Embodiment 2: the utility model mainly is made up of parent 1, ball cover 2, ball 3; The outer wall of described parent 1 is formed integrative-structure by a plurality of bracing frames 1.1 with guiding gutter 1.2; Described bracing frame 1.1 is provided with ball cover 2, in ball cover 2, a ball 3 is installed respectively, and different with embodiment 1 is; Guiding gutter 1.2 adopts helical structure, and the guiding gutter of helical structure can change the flow rate of liquid and the flow direction according to customer requirements.
During use, the utility model directly is placed in sleeve surface gets final product, then just can down-hole operation; After having increased ball; Can not cause the secondary injury, can guarantee the verticality of sleeve pipe accurately, strengthen axially and flexibility radially tube wall; The tube wall of avoiding reducing surface pipe scratches, and has avoided the reduction of the useful life of sleeve pipe.
