加拿大GDD公司生产的SCIP岩芯测试仪存在问题的商榷

Discussion on the core tester SCIP system manufactured by Instrumentation GDD in Canada

加拿大GDD公司生产的SCIP岩芯电参数测试仪,认为是创新测试方法,它将不极化电极既作为电流激励电极,又作为电位测量电极。文章对SCIP岩芯测试仪测试原理进行了分析,认为在测试结果中有不极化电极的过电位混入,测试存在一定的原理性错误,通过对SCIP岩芯测试仪的实测,证实测试装置存在问题。笔者总结了测试岩矿标本电参数中存在的问题,给出了正确测试岩矿标本电参数的装置与仪器以及它们所需的技术要求。

The core electricity parameter tester SCIP system manufactured by Instrumentation GDD in Canada,which said that is an innovative way to measure the electrical property of core samples. It uses non - polarizable electrode as a current incentive electrode and a potential measurement electrode. In this paper,the authors analyse the principle of the SCIP system. They think the test results of the non -polarizable electrode is mixed with the overpotential,which makes the original error. Through the measured results of SCIP, the authors confirm the device has error. The authors summarize the test problems of rock ore specimens electricity parameter. They give the correct equipment and instrument which is used to test the parameters of rock ore samples, and give the necessary technical re- quirements.
