郑和华等:模拟地层高温高压条件的岩样复电阻测量系统,测井技术,1996(4)20,277~281。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复电阻的实验装置。该装置与阻抗分析仪及微机组成了高温高压下岩样复电阻的动态测量系统。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,还可以用于模拟水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。
Zheng Hehua et al .: Rock sample resistivity measurement system for simulating formation high temperature and high pressure, logging technology, 1996 (4) 20, 277-281. Resistivity measurements are widely used in actual well logging and laboratory studies to determine porosity and water saturation. The experimental device for measuring the complex resistance of a rock sample under the conditions of high temperature and high pressure in a simulated formation is introduced. The device and the impedance analyzer and the computer constitute a high temperature and pressure rock sample complex resistance dynamic measurement system. The system quickly and accurately automatically measures and stores data not only for routine laboratory resistivity measurements but also for laboratory displacement measurements that simulate flooding. The measured results of the oil field samples show that the system meets the design requirements.
