Description
The PSZ Comprehensive Logging System is suitable for various logging methods, including single-core NC probes, four-core digital probes, and electrical electrode systems. It provides sufficient NC power capacity and is particularly well-suited for controllable artificial-source neutron probe power supply and measurement.
The system supports USB, serial port, and wireless communication. All probe output data is automatically converted into physical quantities (e.g., apex angle, azimuth, temperature). Internal storage capacity reaches up to 26,000 metres (at 5 cm sampling interval).
It adopts an NC switching power supply supporting both constant-current and constant-voltage modes, with maximum output of 300V / 3A. The electrical probe supply current is up to 500 mA; the power supply waveform and excitation potential sampling position are adjustable, with a time range of 32 ms to 8192 ms. Three electrical logging calibration methods are provided — resistivity, excitation potential, and spontaneous potential — each with multiple gear settings. The system is compatible with various pulse code wheels and features depth positive/negative correction.
The PSZ supports all Zhongdi Yingjie acquisition software, including the well logging suite, VPSJ-2, the latest VPSZ-1, and the ZDWT full-waveform acquisition software (500 points). All operations can be completed via computer using the VPSZ-1 acquisition control software; the panel buttons and display serve only as auxiliary controls. Digital probe signal gain is automatically adjusted according to cable length to ensure accurate and convenient data acquisition.
