The specific embodiment
As shown in Figures 1 to 3, a kind of digital hydraulically created fracture real-time monitoring system, the Real-Time Monitoring computer that comprises crack information processing centre station, links to each other by communication interface and central station, by at least 6 above crack signals collecting substations that wireless network is connected with crack information processing centre station, described crack signals collecting substation image data transfers to crack information processing centre station analyzing and processing and carries out Real Time Monitoring by the Real-Time Monitoring computer after passing through analog/digital conversion.Wherein: crack signals collecting substation comprises signal filtering unit, programmable amplifier, AD conversion unit, digital filter, microprocessor, modem, GPS positioning unit, electric board record cell, power control unit; Information processing centre station in crack comprises modem, data receiver unit, level conversion unit, microprocessor, GPS positioning unit, power control unit; The Real-Time Monitoring computer contains Real-Time Monitoring module, logout playback module, electric board read module and location, crack and computing module.
The course of work of each several part is: after the sensor signal process filtering in the signals collecting substation of crack and programmable amplifier amplify, deliver to 24 A/D converters and carry out analog-to-digital conversion, after converting, delivering to Linear phase FIR digital filter processes, sample rate 1000Hz (or 2000Hz), digital sampled signal after the conversion forms 24 long serial datas, deliver to microprocessor and compress processing, microprocessor control radio modem, according to certain format, with suitable speed sampled digital signal is sent to central station, and delivers to simultaneously the electric board record.
A plurality of radio modems at crack information processing centre station will convert serial signal to from the sampled signal of different Monitor Sub-Station of Less, the data receiver part receives respectively each road serial signal, process 5V is after the 3.3V level conversion, deliver to microprocessor processes, microprocessor gathers the sampling of every road, delivers to computer by the USB mouth and carries out subsequent treatment.The signal that the crack forming process is sent during wellfracturing that substation collects is through after the digital processing, be sent in real time central station by wireless transmission method, central station is crossed the USB oral instructions with the multi pass acquisition data communication device and is delivered to supervisory control comuter, and systems soft ware real-time demonstration on computer screen receives signal waveform, record data, also locates in real time.
Move on computers that program mainly realizes man-machine interaction, formed by Real-Time Monitoring module, event replay module and electric board read module three parts.The Real-Time Monitoring module receives the collection signal of at least 6 above substations in real time, show in real time and receive signal waveform, according to parameter real-time searching crack event is set, the position display positioning result that the calculating event occurs when the crack event is arranged, positioning result shows in three-dimensional coordinate system.The observation file of storage before the event replay module can be opened, with put continuously, put frame by frame, put soon, put slowly, the variety of option careful analysis observation signal waveform such as Fourier analysis, parameter be can change and event and location again automatically identified, also but the manual identification onset time is in order to more accurately locate, can carry out the low pass high-pass filtering to playback signal and process, be convenient to analyze more comprehensively fracturing process.Consider various observing environments, central station is connected with substation and is normally connected, so substation has the electric board memory function, after observation was finished, the available electric board module of reading was read
Go out record data and form file, then analyze with the event playback module.
