Abstract
A rolling centralizer of oil geological drilling mechanism comprises a supporting body arranged on an oil extraction rod or a drilling rod, a supporting frame, and a rolling body arranged in the supporting frame. The supporting frame and the rolling body are embedded in the supporting body together, the supporting body and a sporting part (an oil extraction rod or a drilling rod) are connected in subsection way and move together, the rolling body can freely roll in the supporting frame and separate the sporting part and a friction body, the gliding friction is replaced by rolling friction to reduce abrasion, the service life of the sporting part can be prolonged and the power can be saved.
Description
Technical field:
The novel centralizer that relates to a kind of petroleum geology drilling machinery of this experiment, particularly a kind of rolling element centralizer belongs to the petroleum geology field of mechanical technique.
Background technology:
At present, in petroleum geology drilling machinery, the drilling rod of drilling machinery, moving components such as the sucker rod of oil recovery machiner contact with the borehole wall or oil pipe at work and produce friction, and it is very fast to wear and tear, to making these moving components life-span very low.In order to reduce the wearing and tearing to moving component, the centralizer that is adopted all is to make protective with harder material, and moving component and friction body are kept apart, and avoids moving component to be worn.As the stile of drilling machinery, very quick-wearing loses protective effect with wall friction the time.Its reason is to be sliding friction between the contactant, and this friction is promptly big again to the fast wasted power of component wear.
Summary of the invention:
The rolling element centralizer that the utility model is designed can overcome the shortcoming of above-mentioned centralizer, and it makes rolling element with protective, replaces sliding friction with rolling friction, promptly having reduced wearing and tearing and having saved power again.
The purpose of the utility model rolling element centralizer is achieved in that existing centralizer with the oil recovery machiner sucker rod is an example, and it is contained and held frame by the supporter that is installed on the sucker rod, is installed in to contain the rolling element of holding in the frame, waits composition.Rolling element is held frame and is embedded on the supporter together with rolling element containing that holding can freely roll in the frame and contain, supporter connects with the moving component segmentation and moves with moving component, rolling element contacts with the friction body during motion, moving component and friction body are kept apart, replace sliding friction with rolling friction, reduce wearing and tearing, saved power.
Description of drawings:
Fig. 1 is sucker rod rolling element centralizer assembly figure.
Fig. 2 is drilling rod rolling element centralizer assembly figure.
Fig. 3 is that sucker rod rolling element centralizer contains and holds frame assembly figure.
Fig. 4 is that drilling rod rolling element centralizer contains and holds frame assembly figure.
The specific embodiment:
The rolling element centralizer is by the supporter (1), (5) that are installed on the sucker rod among Fig. 1, Fig. 2, contain and hold frame (2), be installed in and contain the rolling element compositions of holding in the frame (2) such as (8), rolling element (8) is held in the frame (2) and can freely be rolled containing, contain and hold frame (2) and be embedded on the supporter (1) together with rolling element (8), supporter (1) connects with the moving component segmentation and moves with moving component, rolling element during motion (1) contacts with the friction body, moving component and friction body are kept apart, replace sliding friction with rolling friction, reduce wearing and tearing, saved power.
The characteristics of the utility model rolling element centralizer are: simple in structure, and dependable performance, cost is low.
Claims (3)
1, a kind of rolling element centralizer is characterized in that, by the supporter (1), (5) that are installed on the sucker rod, contains and holds frame (2), is installed in and contains the rolling element of holding in the frame (2) (8) and form.
2, rolling element centralizer according to claim 1 is characterized in that, rolling element (8) is held in the frame (2) and can freely be rolled containing, and contains to hold frame (2) and be embedded on the supporter (1) together with rolling element (8).
