- Abstract
The exploitation of Lamadian oil field P layer has been in the ultra-high water stage, there is a serious inefficient circulation of injected water. Low cost asphalt particle profile control technology has been researched and carried out in this reservoir. While, there is still no guidance for size-selection of asphalt particles in application. In this paper, based on simulation profile control experiment in laboratory, using three layer heterogeneous cores with rectangle conducting section, the asphalt particle size had been selected under two kinds of injection rate to match different permeability formation. At the same time, the scour resistance of asphalt particle was evaluated. This paper illusrates that different permeability cores can be injected different particle size limit: 0.06mm asphalt particle can be injected into 500×10-3 m2 permeability core; 0.1mm asphalt particle can be injected into 1500×10-3 m2 permeability core; 0.3mm asphalt particle can be injected into 3000×10-3 m2 permeability core. The bigger the size of asphalt particle, the greater the resistance to scour.
