Abstract
A kind of eight arm rolling wheel centralizers.Mainly solve the problem that has centralizer spring leaf easy fracture now and set upright poor effect.It is characterized in that: center-pole (1) two ends are with the spring slide (3) that is built-in with spring (2) respectively, spring slide (3) upper and lower side is connected with spring capping (5) respectively and connects gland (6), connect on gland (6) the one side center-poles (1) in the spring slide (3) and be with baffle plate (7), be fixed with respectively the push rod (8) that touches mutually with 4 left and right sides support arms (9) on the baffle plate (7), support arm (9) one terminations in the left and right sides are hinged on respectively on the rectangle connecting cylinder (11) that connects on the gland (6), and the corresponding end of left and right sides support arm (9) is hinged and is connected with roller (10) respectively.This eight arms rolling wheel centralizer is not only set upright effect when operation good, and reduce maintenance cost, enlarged range of application.
Description
Technical field:
The utility model relates to the used centralizer of well logging, especially eight arm rolling wheel centralizers in the oil field geologic Exploration Domain.
Background technology:
When the oil field geologic exploration logging, need on logging instrument, connect centralizer.What generally use at present is spring chip centralizer, at the well logging process reed easy fracture of being hit by a bullet, cause the maintenance cost height, and owing to an end of spring leaf is fixed on the axis of centralizer, have only an end to be free to slide, therefore instrument is hampered easily when entering well head and move in well or meets card, and the technological requirement the when mechanical property of its centralizer can not satisfy well logging causes and sets upright poor effect.
The utility model content:
In order to overcome the deficiency that has centralizer spring leaf easy fracture now and set upright poor effect, the utility model provides a kind of eight arm rolling wheel centralizers, and this eight arms rolling wheel centralizer is not only set upright effect when operation good, and reduce maintenance cost, enlarged range of application.
The technical solution of the utility model is: this eight arms rolling wheel centralizer comprises center-pole, the center-pole two ends are with the spring slide that is built-in with spring respectively, spring slide upper and lower side is connected with spring capping respectively and connects gland, connect on the gland one side center-pole in the spring slide and be with baffle plate, be fixed with respectively the push rod that touches mutually with 4 left and right sides support arms on the baffle plate, support arm one termination in the left and right sides is hinged on respectively on the rectangle connecting cylinder that connects gland, and the corresponding end of left and right sides support arm is hinged and is connected with roller respectively.
Left and right sides support arm is connected an end in the above-mentioned scheme with connecting cylinder mounting hole, and the bearing pin that is connected on the connecting cylinder is arranged in the mounting hole, and locking jackscrew is arranged on the connecting cylinder.
The beneficial effect that the utlity model has is: this eight arms rolling wheel centralizer is owing to adopted such scheme, promote steel body arm by circumferential spring and realize radial support, realize contacting with roller with sleeved arms, realize opening and closing of centralizer arm, replace the sliding friction of spring leaf with the rolling friction of roller, solved the problem of spring leaf and sleeve friction spring leaf easy fracture; Because the uprighting force near constant of this centralizer, instrument can enter the minor diameter sleeve pipe from the major diameter sleeve pipe easily, and at inclined shaft and horizontal well good uprighting force is arranged also, thereby improved the effect of setting upright of centralizer, enlarge range of application, reduced maintenance rate, effectively reduce production costs.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-center-pole among the figure, the 2-spring, 3-spring slide, the 4-mounting hole, the 5-spring capping, 6-connects gland, 7-baffle plate, 8-push rod, 9-left and right sides support arm, 10-roller, 11-connecting cylinder, 12-jackscrew.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this eight arms rolling wheel centralizer comprises center-pole 1, center-pole 1 two ends are with spring slide 3 respectively, spring slide 3 is built-in with spring 2, spring slide 3 upper and lower sides are connected with spring capping 5 respectively and connect gland 6, connect on the gland 6 one side center-poles 1 in the spring slide 3 and be with baffle plate 7, be fixed with push rod 8 on the baffle plate 7, push rod 8 touches mutually with 4 left and right sides support arms 9 respectively, support arm 9 one terminations in the left and right sides are hinged on respectively on the rectangle connecting cylinder 11 that connects on the gland 6, the corresponding end of left and right sides support arm 9 is hinged and is connected with roller 10 respectively, left and right sides support arm 9 is connected an end with connecting cylinder 11 mounting hole 4, the bearing pin that is connected on the connecting cylinder 11 is arranged in the mounting hole 4, locking jackscrew 12 is arranged on the connecting cylinder 11.Promote left and right sides support arm 9 by circumferential spring and realize radial support, realize contacting with roller 10 with sleeved arms, realize opening and closing of centralizer arm, replace the sliding friction of spring leaf, solved the problem of spring leaf and sleeve friction spring leaf easy fracture with the rolling friction of roller 10; Because the uprighting force near constant of this centralizer, instrument can enter the minor diameter sleeve pipe from the major diameter sleeve pipe easily, and at inclined shaft and horizontal well good uprighting force is arranged also, thereby improved the effect of setting upright of centralizer, enlarge range of application, reduced maintenance rate, effectively reduce production costs.
