Detailed description of the invention
Hereinafter, based on accompanying drawing, the present invention will be described in detail.
Fig. 1 is the basic structure of magnetic localizer, and Fig. 2 is the schematic diagram of the operation principle of magnetic localizer.The structure of the box cupling magnetic orientation well logging pipe nipple of the present invention is essentially identical with the structure of the magnetic localizer described in Fig. 1, and its operation principle is also similar.
Specifically, the box cupling magnetic orientation well logging pipe nipple of the present invention possesses probe segment, digital-to-analog circuit processes part and CAN transceiver module.Probe segment includes permanent-magnet steel that a pair magnetic pole is relative, iron core between the pair of permanent-magnet steel and is wrapped in the coil on described iron core, as shown in Figure 1, side (that is, side, N pole or side, the S pole) configuration opposite each other that the polarity of the magnetic pole that the permanent-magnet steel that a pair magnetic pole is relative refers to two permanent-magnet steels is identical.In addition, digital-to-analog circuit processes part for processing the signal collected by described probe segment, such as, along with sleeve pipe changes of magnetic field at box cupling, probe segment produces voltage change signal, the signal collected is processed by digital-to-analog circuit process part, and passes to the spread of the rumours system (high speed the spread of the rumours logging instrument) by measuring signal by the CAN of instrument internal.Additionally, CAN transceiver module for transmitting the signal processed by described digital-to-analog circuit process part by CAN to high speed the spread of the rumours logging instrument, and receive the signal from high speed the spread of the rumours logging instrument.
CAN is as ripe industrial bus standard, its interference free performance has obtained sufficient checking, and, the instrument of each mounting of CAN can individually be debugged, accordingly, because the box cupling magnetic orientation well logging pipe nipple of the present invention uses CAN to carry out data communication, so, its interference free performance can be improved, even if also being able to locating sleeve collar location exactly under rugged environment.
Additionally, in the present invention, described permanent-magnet steel is made up of samarium-cobalt material.In the design of the present invention, the processing of permanent-magnet steel have employed samarium-cobalt material different from the past, its aluminum nickel cobalt material commonly used than well logging industry, the magnetic flux of such material is bigger, thus, time at box cupling magnetic orientation well logging pipe nipple is by casing coupling, it is possible to produce more obvious box cupling and measure signal, thus improve the precision of detection.
Additionally, in the present invention, process part at described digital-to-analog circuit and use the control mode of automatic gain, it is possible to all the time the signal of output is controlled in moderate degree.Such as, in the present invention, automatic gain is by measuring the amplitude of first crest realization adjustment automatically, i.e. gather the value of first crest in the case of gain is 1, automatically arranges gain according to this value is bigger than normal or less than normal, thus realizes the dynamic of signal and regulate.
In addition, the number of turn of described coil is determined by the casing diameter (being up to minimum diameter) of experiment different-diameter, so that the analogue signal that records of sensor both will not the least also without departing from range (that is, the number of turn of coil is the value finally decided beforehand through the test signal amplitude of different-diameter sleeve pipe, the number of turn of described coil disclosure satisfy that the semaphore request that various sleeve pipe is measured), in the case of different signal amplitudes, it is possible to realize being adapted to different sleeve pipes by automatic gain control.Additionally, signal is acquired by the high-speed AD that have employed more seniority top digit, the needs of different logging speed can be met.
And then, the invention provides a kind of high speed the spread of the rumours logging instrument, it has box cupling magnetic orientation well logging pipe nipple, i.e., box cupling magnetic orientation well logging pipe nipple it is integrated with in high speed the spread of the rumours logging instrument of the present invention, box cupling magnetic orientation well logging pipe nipple is positioned at the top of described high speed the spread of the rumours logging instrument, and it is connected with the controller of described high speed the spread of the rumours logging instrument by CAN, it is to say, described box cupling magnetic orientation well logging pipe nipple can carry out transmission and the reception of signal between described high speed the spread of the rumours logging instrument by CAN.In the present invention, by independent instrument (box cupling magnetic orientation well logging pipe nipple) is become the pipe nipple that the spread of the rumours is integrated, thus, eliminate most power pack, have employed digital collection scheme and instrument internal bus simultaneously, not only shorten the size of instrument, and due to the motility of digital processing mode, also enhance the instrument adaptability for different casing diameters.
In addition, in high speed the spread of the rumours logging instrument of the present invention, box cupling magnetic orientation well logging pipe nipple is above-mentioned pipe nipple, i.e. this pipe nipple possesses: include permanent-magnet steel that a pair magnetic pole is relative, iron core between the pair of permanent-magnet steel and the probe segment of coil being wrapped on described iron core；For the digital-to-analog circuit process part that the signal collected by described probe segment is processed；And CAN transceiver module, for being transmitted the signal processed by described digital-to-analog circuit process part to described high speed the spread of the rumours logging instrument by CAN, and receive the signal from described high speed the spread of the rumours logging instrument.
Additionally, in high speed the spread of the rumours logging instrument of the present invention, described permanent-magnet steel is made up of samarium-cobalt material.Owing to the magnetic flux of such material is bigger, so, more obvious box cupling can be produced time at casing coupling and measure signal, thus improve the precision of detection.
Additionally, in high speed the spread of the rumours logging instrument of the present invention, process part at described digital-to-analog circuit and use the control mode of automatic gain, it is possible to all the time the signal of output is controlled in moderate degree.
In addition, in high speed the spread of the rumours logging instrument of the present invention, described automatic gain realizes as follows: in the case of gain is 1, gather the value of the crest of first signal detected by described probe segment, automatically configure gain according to this value is bigger than normal or less than normal, thus realize the dynamic regulation of signal.
Additionally, in high speed the spread of the rumours logging instrument of the present invention, the number of turn of described coil can determine according to the diameter of different sleeve pipes.
Describe the present invention as described above.In the present invention, the probe portion of casing joint magnetic positioning logging tool is carried out the redesign in structure, be allowed to preferably adapt to various sizes of sleeve pipe and the well logging situation of severe hole condition；In order to improve the signal to noise ratio of the different the biggest casing size of casing size, and ensure the reliability stability of instrument, the magnetic material etc. of probe portion magnetic cylinder is redesigned；Using CAN as instrument internal bus, it is achieved probe transmits with the data of high speed the spread of the rumours system；Using CAN as the communication bus of instrument internal, it is achieved pop one's head in and the docking of the spread of the rumours system, it is to avoid in traditional magnetic orientation analogue signal transmitting procedure, signal to noise ratio is with the problem of length of cable deteriorate drastically, it is ensured that the stability of measurement result and reliability.
Above the present application is illustrated, but, but be not restricted to that this, it is understood that various change can be carried out in the range of present inventive concept, and, these are within.
