Abstract
The invention relates to a magnetic induction type signal transmission drill pipe joint, which comprises a male joint body, a male joint wire, a male joint ferrite, a male joint coil, a female joint body, a female joint wire, a female joint ferrite, a female joint coil and the like, the drill pipe joint is characterized in that the male joint ferrite is mounted in a groove on the front end of the male joint body, the male joint coil is arranged inside the male joint ferrite, and the male joint wire is connected with the male joint coil. The female joint ferrite is mounted in a groove inside the female joint body, the female joint coil is arranged inside the female joint ferrite, and the female joint wire is connected with the female joint coil. The drill pipe joint can transmit signals between drill pipes through the wires, so that a high-speed channel for wired real-time bidirectional closed-loop measurement and control information transmission while drilling can be established; and the drill pipe joint with a simple structure does not affect the power transfer and drilling fluid circulation of the ordinary drill pipe.
Description
Technical field
The present invention relates to a kind of tool joint that is used for oil, Natural Gas Drilling Operation, can in transferring power, circulating fluid, carry out the wire transmission of signal.
Technical background
Continuous development along with rotary steerable drilling technology, geologic steering drilling technology and advanced drilling technologies such as diagnosis of drilling well dynamic parameter down-hole and control technology; Oil drilling, completion enter informationization, intellectuality and automatic phase, and requirement can be with the various information of boring collection in real time, transmission, processing, feedback and applied geology and well, so that can in time adjust construction technology to drilling process.At present, mud-pulse is measured as one of industrial standard of measurement while drilling (MWD) and the transmission of well logging during (LWD) tool data, and its desirable transfer rate is 2～5bit/s; Numerous parameters can not be really satisfied with boring the requirement of transmission real-time, the high-speed channel of ground and under-well bi-directional closed-loop information transmission can not be set up.So can satisfy normal drillng operation requirement, the wire transmission drilling rod technology that can set up wired drilling real time bidirectional closed loop measurement and control National Information Infrastructure again becomes a key.
Summary of the invention
The objective of the invention is for a kind of magnetic induction type signal transmission drill pipe joint is provided.The realization drilling rod is finished the task of signal wire transmission in transferring power, circulating fluid.
In order to achieve the above object, a kind of magnetic induction type signal transmission drill pipe joint of the present invention, it partly is made up of male joint body, male joint lead, male joint ferrite, male joint coil, female joint body, female joint lead, female joint ferrite, female joint coil etc.The male joint ferrite is installed in the groove of male joint body front end, and the male joint coil is arranged in male joint ferrite inside, and the male joint lead links to each other with the male joint coil.The female joint ferrite is installed in the groove of female joint body interior, and the female joint coil is arranged in female joint ferrite inside, and the female joint lead links to each other with the female joint coil.When male joint body and female joint body are coupled together, leave the gap at the front end of male joint body and the joint of female joint body interior.
A kind of magnetic induction type signal transmission drill pipe joint of the present invention can carry out the wire transmission of signal in transferring power, circulating fluid, set up the high-speed channel of wired drilling real time bidirectional closed loop measurement and control information transmission.
Description of drawings
Fig. 1. a kind of magnetic induction type signal transmission drill pipe joint schematic diagram
The specific embodiment
With reference to accompanying drawing 1, will be described in detail specific embodiments of the present invention.
In Fig. 1, male joint ferrite 4 is installed in the groove of male joint body 1 front end, and male joint coil 5 is arranged in male joint ferrite 4 inside, and male joint lead 3 links to each other with male joint coil 5.Female joint ferrite 6 is installed in the groove of female joint body 2 inside, and female joint coil 7 is arranged in female joint ferrite 6 inside, and female joint lead 8 links to each other with female joint coil 7.
The present invention couples together male joint body 1 and female joint body 2 when using, and also leave gap at the front end of male joint body 1 and the joint of female joint body 2 inside this moment.When having current signal to transmit in the male joint lead 3, current signal is during by male joint coil 5, under the effect of male joint ferrite 4, form an electromagnetic field, and then under the induction of female joint ferrite 6, also can induce current signal in female joint coil 7, current signal just can transmit by pin and box sub like this; If have current signal also can pass in the male joint lead 3 in the same female joint lead 8.Can under the situation that does not influence drilling rod transferring power, circulating fluid function, realize wired transmitted in both directions of signal.
