Description
technical field [0001] The invention relates to the technical field of electrodes for measuring the resistivity of rock core saturation, and relates to a semi-permeable diaphragm liquid outlet electrode. Background technique [0002] For a long time, the semi-permeable diaphragm core saturation resistivity measurement electrode has been measured by the two-pole method of the displacement electrode and the liquid outlet electrode, and the liquid outlet is directly coupled with the core, semi-permeable diaphragm and stainless steel electrode. , the coupling effect is poor, and the contact error between the core and the electrode is large. Although this method will not affect the measurement accuracy of the core saturation, as the water saturation of the core decreases, the contact resistance of the core will increase exponentially, resulting in a continuous increase in the measurement error of the core saturation resistivity. Contents of the invention [0003] The present i...
