摘要
介绍了一种对油水选择性渗透能力强的新型水泥浆体系,即油溶性水泥浆体系。该水泥浆体系由增孔剂、连通剂和相渗剂3种基本试剂组成。在理论分析的基础上,通过大量的室内试验从天然的油溶性有机物中优选出能大幅度提高水泥石孔隙的增孔剂——ZKJ 1。为了使水泥石孔隙之间相互连通以及进一步提高水泥石对油水的选择性渗透能力,优选出YRJ作为连通剂和相渗剂。3种外加剂配合使用不但可以使水泥石具有良好的油相渗透率,而且还能使水泥石具有较高的强度。
A new cement slurry system with strong selective permeability to oil and water, namely oilsoluble cement system, was introduced. It is composed of three kinds of basic agent including pore-enhancing grains, 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.
