О ВОЗМОЖНОСТИ ОЦЕНКИ СТЕПЕНИ ОЧИЩЕНИЯ ПРИЗАБОЙНОЙ ЗОНЫ ПЛАСТА ПО ДАННЫМ ГИДРОДИНАМИЧЕСКИХ ИССЛЕДОВАНИЙ СКВАЖИН

The article presents the dependences of the coefficient of well productivity on depression, based on the results of hydrodynamic studies of wells in a number of fields in Western Uzbekistan. The data show that they can be divided into four groups. Each selected group has its own dynamics of changes in the well productivity coefficient, which allows to draw certain conclusions about the time and degree of purification of the bottom hole formation zone.
