Abstract
The effect of changes in the filtration properties of the near-wellbore production zone (NWPZ) on the radius of the outer boundary of the formation (r k ) and well flow rate is considered. On the basis of analytical calculations, it is shown that the size of the drained zone of the reservoir decreases with deteriorating properties of the BHZ. Therefore, taking into account the change in r k , the fluid inflow decreases to a lesser extent than without taking into account the change in r k .
