Method for measuring moisture content of oil-based mud

The invention relates to the technical field of geochemical analysis, in particular to a method for measuring the moisture content of oil-based mud, which comprises the following steps of: 1, preparing test oil-based mud with different moisture contents; step 2, immersing the test electrode in test oil-based mud with different water contents, applying an excitation signal, measuring impedance values of the oil-based mud under different water contents, and fitting by taking the water contents as abscissas and the impedance values as ordinates to obtain an oil-based mud water content calculation formula based on the impedance values; and 3, measuring the water content of the oil-based mud to be measured according to the calculation formula of the water content of the oil-based mud. The water content of the oil-based mud is monitored through the impedance characteristic of the oil-based mud, the water content of the oil-based mud can be detected in real time, the working state and the working performance of the
