Abstract
The utility model relates to one and to go into the well cable eccentric abrasion prevention technical field, and particularly one is gone into the well cable centralizer.The circular tube shaped centralizer body lower end of this device is designed with thread, side, circular tube shaped centralizer body upper end is connected with righting wheel support, righting wheel pedestal upper end is designed with mandrel fixed groove, righting wheel mandrel two ends are all fixed in mandrel fixed groove by hold-down screw, and righting wheel mandrel is provided with righting wheel.The utility model achieves and ensures that in test construction, cable is in center all the time when removing, and not hanging and touches wellhead equipment, preventing cable from causing eccentric wear because departing from center, extend the application life of cable, reduce the wearing and tearing to wellhead equipment.Overcome cable serious wear in existing test construction, easy to hangly to touch, the deficiency of the wellhead equipment that weares and teares.
Description
Technical field:
The utility model relates to one and to go into the well cable eccentric abrasion prevention technical field, and particularly one is gone into the well cable centralizer.
Background technology:
Cable is very general in modern oil well test, in order to parameter various under detecting shaft, just with cable tester need be sent in well and measure, cable is in the process of going into the well, due to the difference of aboveground cooperating equipment, lower sheave, top sheave, 3, well head is difficult to ensure in optimum position, like this remove cable in cable process can at well head everywhere in off-centered position, and make cable can not vertically in lower going-into-well, be ground to sometimes wellhead equipment (as box cupling or screw thread first-class), simultaneously also very serious to the wearing and tearing of cable, the darker equipment attrition of well must be more serious.
Utility model content:
The technical problems to be solved in the utility model is to provide one and goes into the well cable centralizer, the arrangement achieves and ensure that in test construction, cable is in center all the time when removing, do not hang and touch wellhead equipment, prevent cable from causing eccentric wear because departing from center, extend the application life of cable, reduce the wearing and tearing to wellhead equipment.Overcome cable serious wear in existing test construction, easy to hangly to touch, the deficiency of the wellhead equipment that weares and teares.
Technical solution adopted in the utility model is: one is gone into the well cable centralizer, comprises circular tube shaped centralizer body; Circular tube shaped centralizer body lower end is designed with thread, side, circular tube shaped centralizer body upper end is connected with righting wheel support, righting wheel pedestal upper end is designed with mandrel fixed groove, righting wheel mandrel two ends are all fixed in mandrel fixed groove by hold-down screw, and righting wheel mandrel is provided with righting wheel.
The beneficial effects of the utility model are: the utility model ensures that in test construction, cable is in center all the time when removing, do not hang and touch wellhead equipment, preventing cable from causing eccentric wear because departing from center, extending the application life of cable, reducing the wearing and tearing to wellhead equipment.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, one is gone into the well cable centralizer, comprises circular tube shaped centralizer body 1; Circular tube shaped centralizer body 1 lower end is designed with thread 2, side, circular tube shaped centralizer body 1 upper end is connected with righting wheel support 3, righting wheel support 3 upper end is designed with mandrel fixed groove 7, righting wheel mandrel 4 two ends are all fixed in mandrel fixed groove 7 by hold-down screw 5, righting wheel mandrel 4 are provided with righting wheel 6.
During use, on box cupling the utility model being connected to shaft mouth test or other equipment, the opening direction of righting wheel support 3 is pointed to cable transfer direction.During construction operation, cable is put into the groove of righting wheel 6; like this when removing cable; cable directly can contact to produce with righting wheel 6 and rub; and drive righting wheel 6 to rotate; the friction of cable and equipment when eliminating operation; ensure that cable runs under the operation without wearing and tearing, protect again the wearing and tearing that other equipment are subject to cable.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
