Özet

It is obvious that estimation of filter cake thickness is one of the important parameters in drilling operations. In this study, dynamic filtration data was used to determine the filter cake thickness. Predictions were made through linear filtration cake model by using dynamic filtration experimental data. Linear filtration model can be used to approximate radial filtration model; only the thickness of the filter and filter cake is sufficiently smaller than the radius of the filter surface exposed to slurry. It was observed that the thickness of the filter cake at dynamic conditions is less than that of static conditions since there is no continuous deposition due to erosion effects at dynamic conditions.
