摘要
超分子驱油技术是一种新型的提高采收率技术,由于WMM-100与带负电的岩石表面之间有较强的超分子化学作用(氢键、配位键、堆积效应、静电相互作用等);且WMM-100之间可以通过共享一个或多个苯环聚合起来吸附在岩石表面形成超共轭体系。对WMM-100驱油剂性能测定后发现:低粘度的超分子驱油剂在多孔介质中流动时,具有高的阻力系数和附加流动阻力,与原油间粘滞力高,并有良好的驱油效果,可以提高采油速度,适合于聚合物驱后进一步提高采收率。
Supramolecular oil displacement technology is a new method for enhanced oil recovery. The performance of supramolecular oil displacement agent (WMM-100) has been tested in this paper. Because of the supramolecular acting force between WMM -100 and the surface of rock which has negative charges, and the conjugate action between WMM-100 by sharing one or more benzene rings, when low viscosity WMM-100 solution is flowing in porous medium, it has the high resistance coefficient, high flow resistance; and it can enhance oil recovery and production rate, which can be used to enhance oil recovery after polymer flooding.
