The article gives an analysis of the causes of colmatation of the bottomhole zone of the well at the initial autopsy. It is shown that the pollution of the bottomhole zone significantly affects well productivity and formation perme-ability, determined by the results of hydrodynamic studies. The reasons for the contamination of the bottomhole formation zone are considered. De-pendence of the influence of a clay solution on the oil permeability of cores and the dependence of a decrease in the productivity of a well on the depth of contamination of the bottomhole zone are presented. The study of the colmatation process at the opening of oil and gas deposits was carried out, and the stages were identified when technological liquids were in contact with the productive collector. The conclusion is made that hydrodynamic studies of wells are an essential tool for monitoring the rational development of hydrocarbon fields and provide real information allowing to make prompt decisions as quickly as possible.
