模拟地层高温高压条件的岩样复电阻测量系统

电阻率测量广泛地应用于实际测井和实验室研究中，以确定孔隙度和含水饱和度。介绍了自行研制的在模拟地层的高温高压条件下测量岩样电阻的实验装置，该装置与阻抗分析仪及微机组成了高温下岩样民阻的动态测量系统。该系统能快速、准确地自动测量，存储数据，不仅能用于常规的实验室电阻率测量，还可以用地模拟不淹过程的实验室驱替测量，对油田岩样的实测结果表明，该系统达到了设计要求。

Complex Resistance Measuring System of Rock Sample under High Temperature and High Pressure

Resistivity measurement is widely used to determine porosity and water saturation in well logging and laboratory study. A laboratory setup is introduced to measure complex resistance of rock sample under high temperature and high pressure. This setup combined with an impedance analyzer and a micro-computer makes up a dynamic measuring system, which can be used for complex resistance of rock sample, but for displacement measurement of the simulated water flood process. The measured results of rock sample showf that the system is up to the requirement.
