A Theoretical Analysis of Profile Conformance Improvement Due to Suspension Injection

This study is focused on a solution for the problem of suspension penetration in porous formation. Such forms basis injection profile diversion technology oil reservoir sweep improvement. A conventional model deep-bed flow was used to describe process. The slug followed by water injection, and inflow before after treatment investigated. For first time, criteria that determine effectiveness improvement process are introduced. effect filtration coefficient particle depth studied. specific value maximum achieved. obtained analytical generalized multi-reservoir strata with poor interlayer crosslinking. efficiency conformance described differences root-mean-square deviations velocities interlayers from mean values treatment. It shown complex criterion should include reduction total injectivity. An increase volume improves injectivity but decreases an injector.
