The Rock Physics Lab
Introduction
The rock physics lab has been built since 2015 and by now there is a SCMS-F multi-parameter measure system with several auxiliary apparatuses. In this lab, the main works are focus on the measurement and analyses of ultra-elastic velocities, porosity, resistivity and permeability in well-consolidate and unconsolidated rock samples.
The SCMS-F system is manufactured by the state key lab of marine geology in Tongji university and oil and gas reservoir geology and exploitation in Southwest petroleum university. It is designed to measure multi rock physical parameter in high accuracy with an auto-control system. It can be used to simulating gas hydrate in high pressure and low temperature. Furthermore, the rock physical parameters, such as ultra-elastic velocities, porosity, permeability and resistivity, can also be measured for well-consolidate and unconsolidated core samples in high pressure and temperature. The following parts are the key parameters used in core sample tests.
