Abstract
The utility model discloses a lantern body stabilizer. The stabilizer comprises a spindle (2), slide seats (3), an elastic piece (5) and a spring steel plate (6). The left and the right sides of the spindle (2) are respectively sleeved with the slide seats (3). The spring steel plate (6) is separately connected with the slide seats (3) sleeved at the left and the right sides of the spindle (2). The elastic piece (5) is separately connected with the slide seats (3) sleeved at the left and the right sides of the spindle (2). By adjusting the length of the elastic piece into the slide seats, the stabilizer can change a linear distance between the slide seats at the two ends of the spring steel plate. The arc height of the spring steel plate is adjustable, so that stabilizing strength and diameter of the spring steel plate are adjustable, and then the stabilizer meets the stabilizing requirements of logging instruments have different stabilizing strength and borehole diameters.
Description
Technical field
The utility model relates to petroleum well logging technology field, particularly a kind of lantern body centralizer.
Background technology
At present, in the lantern body centralizer using, steel spring plate size during every kind of centralizer free state is all unique fixing, thus for the dynamics of steel spring plate and the size of the eye of logging well, be all basic fixing, so the scope of application is fixed.When the local change of well is large, or after the long-time use of steel spring plate, while there will be elasticity weakened condition, lantern body centralizer just can not well carry out effective righting to logger, can exert an influence to the certainty of measurement of logger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can carry out to logger the lantern body centralizer of effective righting.
For solving the problems of the technologies described above, the utility model provides a kind of lantern body centralizer, comprising: main shaft 2, sliding seat 3, elastic component and steel spring plate 6; The left and right sides of described main shaft 2 is socketed with respectively described sliding seat 3; Described steel spring plate 6 is connected with the described sliding seat 3 that is socketed in described main shaft 2 left and right sides respectively; Described elastic component is connected with the described sliding seat 3 that is socketed in described main shaft 2 left and right sides respectively.
Further, described sliding seat 3 is provided with spiral helicine groove, and the two ends of described elastic component are separately positioned in described groove, thereby the described sliding seat 3 that is socketed in described main shaft 2 left and right sides is linked together.
Further, the two ends of described steel spring plate 6 are plugged on respectively in the groove of the described sliding seat 3 that is socketed on described main shaft 2 left and right sides.
Further, the two ends of described steel spring plate 6 are plugged on respectively in the groove of the described sliding seat 3 that is socketed on described main shaft 2 left and right sides, and fix with connector.
Further, described connector is bearing pin.
Further, described elastic component is extension spring.
Further, described lantern body centralizer also comprises sealing ring 1, and described sealing ring 1 is separately positioned on the two ends of described main shaft 2.
Further, steel spring plate 6 is curved.
The lantern body centralizer that the utility model provides, the length that can enter sliding seat by adjustable elastic part changes the air line distance of steel spring plate two ends sliding seat, can regulate the camber of steel spring plate, thereby the strength of steel spring plate righting and diameter are adjusted, thereby realized the righting requirement that a kind of lantern body centralizer meets the logger of different righting dynamics and different borehole sizes.
Accompanying drawing explanation
The structural representation of the lantern body centralizer that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Referring to Fig. 1, a kind of lantern body centralizer that the utility model embodiment provides, comprising: main shaft 2, sliding seat 3, elastic component 5 and steel spring plate 6.Elastic component can adopt extension spring to realize, certainly other to be equal to alternative parts also passable.The left and right sides of main shaft 2 is socketed with respectively sliding seat 3.Sliding seat 3 is provided with spiral helicine groove, the two ends of extension spring is screwed in respectively in the groove of sliding seat 3, thereby the sliding seat 3 that is socketed in main shaft 2 left and right sides is linked together.The two ends of steel spring plate 6 are plugged on respectively in the groove of the sliding seat 3 that is socketed on main shaft 2 left and right sides, with bearing pin 4, are connected and fixed.The shape of steel spring plate 6 is curved.Finally, at the two ends of main shaft 2, be respectively charged into sealing ring 1.
Because extension spring is the two ends that spiral is screwed in sliding seat 3, therefore can change by the length that regulates extension spring to be screwed into sliding seat 3 air line distance of steel spring plate 6 two ends sliding seats 3, can regulate the camber of steel spring plate 6, thereby strength and diameter to steel spring plate 6 rightings are adjusted, thereby realize the righting requirement that a kind of lantern body centralizer meets the logger of different righting dynamics and different borehole sizes.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
