The form real-time Transmission of electric signal is to shrapnel;Shrapnel will be received by the electric connection between annular protrusion and non magnetic drill collar
Measurement data as electronic signals real-time Transmission to non magnetic drill collar;Non magnetic drill collar is made of conductive material, can will measure
Data are as electronic signals by non magnetic drill collar self transmission to ground installation, so that ground construction personnel can obtain in time
The measurement data for the down-hole formation that measurement while-drilling instrument acquires in real time in time carries out measurement data specifically handling, analyze,
Preferably to instruct wellbore construction.
By above-mentioned Sample Scenario, the device provided by the embodiments of the present application that electrically conducts is demonstrated, since shrapnel being inserted into
The limiting section at both ends so that shrapnel is connected with limiting section, in use, limiting section can be connected with the electrode of measurement while-drilling instrument;
In lower going-into-well, the shrapnel of radial dilatation can contact again with non magnetic drill collar, be electrically connected, so as to by measurement while-drilling instrument
The measurement data of acquisition contacts the electric connection to be formed with non magnetic drill collar by shrapnel and is transmitted to non magnetic drill collar, solves really existing
Have be stored in equipment the technical issues of measurement while-drilling instrument and non magnetic drill collar can not efficiently, easily be connected, reaching can be with
Efficiently, measurement while-drilling instrument and non magnetic drill collar are easily connected, with earthward equipment real-time Transmission measures number by non magnetic drill collar
According to technique effect.
Although mentioning different specific embodiments in teachings herein, the application is not limited to be industry
Standard or the described situation of embodiment etc., certain professional standards or the implementation base described using self-defined mode or embodiment
On plinth embodiment modified slightly can also realize above-described embodiment it is identical, it is equivalent or it is close or deformation after it is anticipated that
Implementation result.It, still can be with using these modifications or the embodiment of deformed data acquisition, processing, output, judgment mode etc.
Belong within the scope of the optional embodiment of the application.
Although this application provides the method operating procedure as described in embodiment or flow chart, based on conventional or noninvasive
The means for the property made can include more or less operating procedures.The step of being enumerated in embodiment sequence is only numerous steps
A kind of mode in execution sequence does not represent and unique performs sequence.It, can when device or client production in practice performs
With according to embodiment, either method shown in the drawings sequence is performed or parallel performed (such as at parallel processor or multithreading
The environment of reason, even distributed data processing environment).Term " comprising ", "comprising" or its any other variant are intended to contain
Lid non-exclusive inclusion, so that process, method, product or equipment including a series of elements not only will including those
Element, but also including other elements that are not explicitly listed or further include as this process, method, product or equipment
Intrinsic element.In the absence of more restrictions, be not precluded the process including the element, method, product or
Also there are other identical or equivalent elements in person's equipment.
Although depicting the application by embodiment, it will be appreciated by the skilled addressee that the application there are many deformation and
Variation is without departing from spirit herein, it is desirable to which appended embodiment includes these deformations and changes without departing from the application.
