METHOD AND APPARATUS FOR SELECTIVE ACID DIVERSION IN MATRIX ACIDIZING OPERATIONS |
摘要 |
An apparatus and method for selectively delivering a fluid to a targeted area through the use of vortices that are experiencing Taylor-Couette flow. Rotation of the outer surface of a body of the apparatus causes fluid within the annular area between a wellbore and the outer surface to form opposing vortices, which can then be used to selectively deliver the fluid to the targeted area, such as areas of low permeability of a reservoir, in order to improve flow characteristics of a producing area. |
