Due to the measurement principle, the mud needs to be taken out for detection, and generally only the mud specific gravity at the groove hole position is measured, and the mud specific gravity at the groove hole position is taken as the mud specific gravity in the whole groove. However, in fact, the mud is not uniformly distributed in the groove, and due to the action of gravity, there is a certain stratification phenomenon, and the specific gravity changes along the groove depth. The detection result of the mud specific gravity at the groove hole position is used to represent the mud in the whole groove, and there is serious data distortion.
