Laboratory Study on Optimization of Oil-Soluble Cement Material
A new cement slurry system with strong selective permeability to oil and water, namely oil-soluble cement system, was introduced. It is composed of three kinds of basic agents including pore-enhancing grains, pore-connecting agent and phase-permeability enhancing agent. The pore enhancing grains-ZKJ-1, which can broaden the pore significantly was obtained from many natural oil soluble organics. In order to further interconnect the cement stones’ pores and enhance the selective permeability to oil and water, the YRJ was selected as the connecting agent and phase-permeability enhancing agent. Combined with three other agents, the cement slurry has a good selective permeability to water and oil and high strength.
