The Researching On TCP Well Logging Of Signal Acquisition And Real-time Waveform Display

Tubing conveyed perforating technology is one of the most popular perforating technologies. Past operations personnel selection at the wellhead listening to the sound, touching the tubing to feel vibrations and other methods to determine tubing conveyed perforating detonate it or not, but the presence of these factors of insecurity and false methods. Therefore wellsite vibration signal acquisition in the software in the form of real-time waveform display and automatically determine the initiation point through intelligent recognition software, and ultimately draw conclusions and judgments based on real-time judge.The thesis mainly studies the signal collection technology and real-time waveform display technology which based on tubing conveyed perforating.Computer as the center, important part of the signal collector, with sensors, signal conditioning circuit, A/D conversion module and microcomputer system compose data acquisition system, collectting signal via the universal standard interface bus module acquisition. Useing view segmentation of static, interface design of engineering, list, MFC standard library implementation dialog box and simple drawing technology to show real time waveform, also show different times’ waveform when moving the scroll bar. Researching TCP perforation monitoring system to sample and store dates through the combination of acquisition and display phase method, and making the system with waveform directly display the testing data and perforating initiating point and initiation time.The full text with Visual C++ 6.0 as the platform, combined with MFC class library designed main interface, and split view, design desired waveform display window, and ultimately to display waveforms, to achieve regional waveform selection, printing and other functions to generate reports.
