Abstract
This disclosure relates to a kind of downhole instrument structure of giving up, it include: instrument upper end and instrument lower end, the instrument upper end and instrument lower end pass through transmission axis connection transmission nut, give up cam of the transmission nut limit connection for cannot come off instrument upper end and instrument lower end during going into the well.The present invention, which can be realized, to be reliably connected between two components of downhole instrument and is reliably detached from.The device is suitable for oil field institute the downhole instrument in need that be detached between two components of underground completion.
Description
Technical field
The present invention relates to a kind of downhole instrument structures of giving up.
Background technique
In the course of work of oil field well instrument, it is often necessary to a part of component of instrument is separately positioned at underground,
For the long term monitoring of downhole data, the design for structure of giving up on instrument is to ensure that the key that can the movement smoothly complete.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of downhole instrument structure of giving up is provided, downhole instrument is realized
It is reliably connected between two components and is reliably detached from.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of downhole instrument structure of giving up, it is special
Sign is, comprising: instrument upper end and instrument lower end, the instrument upper end and instrument lower end pass through transmission axis connection transmission nut,
Give up cam of the transmission nut limit connection for cannot come off instrument upper end and instrument lower end during going into the well.
Compared with prior art, the invention has the following beneficial technical effects:
Structure is simple, comprising: instrument upper end and instrument lower end, the instrument upper end and instrument lower end pass through transmission axis connection
Transmission nut, the transmission nut limit connection is for losing instrument upper end with what instrument lower end cannot come off during going into the well
Hand cam.It can be realized and be reliably connected between two components of downhole instrument and be reliably detached from.The device is suitable for all need in oil field
The downhole instrument being detached between two components is completed in underground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of downhole instrument of the invention with structure of giving up；
Fig. 2 is the status diagram of the invention reached when giving up position；
Fig. 3 is the status diagram after the present invention gives up.
Appended drawing reference signal
1-2-3-reduction torsion spring of cam of giving up of instrument upper end
4-transmission nut 5-transmission shaft, 6-instrument lower ends
Specific embodiment
Below by specific embodiment, present invention is further described in detail, but these embodiments are only that citing
Illustrate, the scope of the present invention is not defined.
Please refer to Fig. 1 to Fig. 3, downhole instrument of the invention structure of giving up includes: instrument upper end and instrument lower end, described
Instrument upper end and instrument lower end by transmission axis connection transmission nut, the transmission nut limit connection for make instrument upper end with
What instrument lower end cannot come off during going into the well give up cam.
In one embodiment, the transmission axis connection motor.
In one embodiment, pipe nipple is launched in the instrument upper end connection.
In one embodiment, envelope pressure measurement short is tested in the instrument lower end connection.
In one embodiment, elastic device is installed on the cam of giving up.
In one embodiment, the elastic device is torsional spring.
In one embodiment, the limit is along the axial movement certain distance of transmission shaft.
In one embodiment, the distance is greater than 6mm.
Fig. 1 to Fig. 3 is please referred to, during going into the well, cam 2 of giving up guarantees to test instrument under the position-limiting action of transmission nut 4
It cannot come off between device upper end 1 and instrument lower end 6.When downhole instrument reach it is specified give up position when, downhole instrument generally can be according to
By the corresponding position of itself positioning mechanism seat in oil pipe.The motor in downhole instrument drives the rotation of transmission shaft 5 in turn at this time
When driving transmission nut is moved to diagram right greater than 6mm, transmission nut releases the limit of cam, above mentions instrument band moving cam
Overturning can be realized dispensing pipe nipple and test the disengaging between envelope pressure measurement short.Torsional spring 3 is installed on cam, guarantees cam on not
Always initial upright state is in when mentioning instrument, if being not desired to execute movement of giving up at this time, structure of giving up can also reset.
The invention, which can be realized, to be reliably connected between two components of downhole instrument and is reliably detached from.The device is suitable for oil field
In need complete the downhole instrument that is detached between two components in underground.
The present invention realizes following beneficial technical effect:
Structure is simple, comprising: instrument upper end and instrument lower end, the instrument upper end and instrument lower end pass through transmission axis connection
Transmission nut, the transmission nut limit connection is for losing instrument upper end with what instrument lower end cannot come off during going into the well
Hand cam.It can be realized and be reliably connected between two components of downhole instrument and be reliably detached from.The device is suitable for all need in oil field
The downhole instrument being detached between two components is completed in underground.
Although the present invention has chosen preferable embodiment and discloses as above, it is not intended to limit the present invention.Obviously, it is not necessarily to here
Also all embodiments can not be exhaustive.Any this field researcher without departing from the spirit and scope of the present invention,
The design method and content that all can be used in embodiment disclosed above are changed and are modified to research approach of the invention, because
This, all contents without departing from the present invention program, research essence according to the present invention is to any simple made by above-described embodiment
Modification, Parameters variation and modification, belong to the protection scope of the present invention program.
