Description

Logger righting plug
Technical field
The utility model belongs to an auxiliary pipe nipple in oil well logging industry in logger, particularly a kind of logger righting plug.
Background technology
At present, logger in the process of going into the well, instrument all must connect special plug bottom, because the external diameter of this kind of plug is the same with instrument external diameter, therefore its effect is generally for buffering to instrument in instrument sealing and decentralization process.The stopper structure of this structure is simple, but shortcoming is: the first, because outside dimension is the same with logger outside dimension, therefore cannot avoid bottom instrument and collision between the borehole wall (or casing wall), can produce harmful effect to the application life of instrument; Second, usually need to install centralizer additional when sound wave quasi-instrument is logged well, in small size well (or sleeve pipe) during well logging, because sound wave quasi-instrument bottom does not have righting structure, 1 centralizer can only be respectively installed additional at the two ends of sound wave quasi-instrument, the quantity of therefore installing centralizer in practical operation has 1 to become 2, adds workload.
Utility model content
The purpose of this utility model is to provide a kind of logger righting plug, not only can effectively avoid bottom instrument and collision between the borehole wall (or casing wall), reduce the impact on instrument application life; And when logging well in small size well (or sleeve pipe) for sound wave quasi-instrument, the quantity installing centralizer additional being reduced to one by two, reduces working strength.
The purpose of this utility model is realized by following technical proposals.
Logger righting plug, comprise plug body, it is spherical rubber plug that the end of described plug body installs a bottom additional, be connected with described plug body inside the rubber plug held is cylinder shape groove, the cylinder insert of cylinder shape groove and plug end of body projection, steady pin is applied in the through hole in the rubber plug after insert and plug body cylinder; The other end of plug body is provided with a blind hole, and the periphery wall of described plug body is provided with sealing ring and snap ring successively, is provided with threaded collar along the external perisporium of the plug inside snap ring.
Further, the cylinder interior of described plug end of body projection is provided with limiting stand.
Further, described threaded collar to be pressed on baffle ring and to connect with the limiting stand on plug body, and snap ring is located by round wire circlip.
Further, described threaded collar end, by screw fastening, connects with the limiting stand on plug body.
Further, the excircle of described rubber plug is be provided with six protruding righting arm structures, and point distribution such as six righting arm circumferencial directions, leaves gap between adjacent two righting arms.
Further, described six protruding righting arm external diameters are less than small size well or casing inner diameter.
Further, described rubber plug is connected with plug body and holds as being provided with cylinder shape groove structure, leaves the through hole running through steady pin wherein between a pair righting arm.
Further, described plug body adopts metal material.
Compared with prior art, the beneficial effects of the utility model are:
1) this righting plug have employed bottom for spherical rubber plug, reduces the resistance of instrument in small size well (or sleeve pipe), is convenient to the buffering to instrument in instrument sealing and decentralization process.
2) this righting plug have employed the righting arm structure of petal type projection, effectively avoids bottom instrument and collision between the borehole wall (or casing wall), reduces the impact on instrument application life;
3) protruding righting arm external diameter is less than small size well or casing inner diameter, not only solves bottom instrument and collision problem between the borehole wall (or casing wall), eliminate bring thus may on the impact in instrument application life;
4), when logging well in small size well (or sleeve pipe) for sound wave quasi-instrument, the quantity installing centralizer additional is reduced to one by two, reduces working strength.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly clear and definite, below in conjunction with accompanying drawing 1, detailed description of the invention of the present utility model is described in further details.At this, schematic description and description of the present utility model for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, the utility model logger righting plug, comprise plug body 1, installing a bottom additional in one end of righting plug body 1 is spherical rubber plug 8, the external diameter of rubber plug 8 is more smaller than undersized well (or casing inner diameter), the shape of cross section of rubber plug 8 can not be totally-enclosed form, leave certain space.Being connected with plug body 1 inside the rubber plug 8 held is cylinder shape groove, the cylinder insert of cylinder shape groove and plug body 1 end bosses, and steady pin 7 is applied in the through hole in the rubber plug 8 after insert and plug body 1 cylinder; The other end of righting plug body 1 is provided with a blind hole, the periphery wall of plug body 1 is provided with successively sealing ring 2 and round wire circlip 3, is provided with threaded collar 6 along plug body 1 periphery wall inside round wire circlip 3.The cylinder interior of plug body 1 end bosses is provided with limiting stand, and threaded collar 6 to be pressed on baffle ring 5 and to connect with the limiting stand on plug body 1, and snap ring 4 is located by round wire circlip 3.Threaded collar 6 end, by screw fastening, connects with the limiting stand on plug body 1.
As shown in Fig. 2 (a), 2 (b), 2 (c), rubber plug 8 for outer end be spherical shape, periphery is provided with six righting arm structures, and point distribution such as six righting arm circumferencial directions, leaves larger space between adjacent two righting arms.Rubber plug 8 is connected with plug body 1 and holds as being provided with cylinder shape groove structure, leaves the through hole running through steady pin 7 wherein between a pair righting arm.
During utility model works, first, successively sealing ring 2, threaded collar 6, baffle ring 5, snap ring 4 are enclosed within above plug body 1 successively, and entangle locking with round wire circlip 3.And then two sealing rings are enclosed within plug body 1.Finally, load rubber plug 8, and with steady pin 7 fix in position.
Plug body of the present utility model 1 and rubber plug 8 are independently two parts, use steady pin assembly connection each other.Plug body 1 adopts metal material.
The shape of cross section at the maximum gauge place of rubber plug 8 is not totally-enclosed form, and adopt the form of structure of righting arm, the maximum outside diameter size of rubber plug 8 is greater than connected instrument outside dimension.Larger space is left between two between righting arm.Like this, going into the well through mud drilling liquid, reducing the resistance of logger in the process of going into the well; When guaranteed strength, leave larger space buffer instrument between two between righting arm to the collision of the borehole wall.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
