Abstract:
This paper considers the nonstationary filtration of a homogeneous elastic fluid in a rigid, inhomogeneous, multilayer bed with no hydrodynamic communication between interbeds. The effect of wellbore crossflow between interbeds after stopping of well operation is studied numerically. It is shown that the volume and time of fluid crossflow between the interbeds are comparable to the volume of injection and the time of chemical treatment of wells. It is concluded that crossflows can be used for selective injection of chemicals. A procedure is proposed to control the volume of selective fluid injection into a well by changing the injection rate.
