Abstract

Abstract: In this paper, the selective blocking ability of double crosslinking gel plugging agent was tested. The parallel core experiment was conducted by using the fractures with different permeability sizes in the chamber. We investigated the injection of gel in simulated fractures, the liquid distribution ratio, the breakthrough of pressure gradient, water plugging rate, oil plugging rate and erosion resistance with different size fractures. The selective plugging mechanism of double crosslinking gel plugging agent was analyzed.
