Abstract
A method for in-depth fluid diversion includes a first step and one or more second steps. The first step includes simultaneously introducing a preformed particle gel (PPG) material and one or more shrinking agents to a first position in a high-permeability zone via an injection well, and introducing water into the high-permeability zone via the injection well, thereby contacting the water with the PPG material to form water-swelled PPG particles within fractures of the high-permeability zone at the first position. The water-swelled PPG particles in the high-permeability zone can pack the fractures, thereby generating a fluid diversion to control the water flow to an adjacent low-permeability zone. A stage-by-stage fluid diversion system is also disclosed.
