    摘要:

    针对新疆油田低渗透储藏开发需求,通过表/界面性能、润湿性、防膨性能测定和岩心驱替实验等常规实验 手段,研究了纳米驱油剂iNanoW1.0的性能特征。研究结果表明,纳米驱油剂iNanoW1.0在表/界面张力、润湿性 方面与水相近,可减少水分子间的相互作用力,有利于启动压力降低,同时还能提高防膨剂的防膨效果,有助于 水敏油藏的开发。岩心实验结果证明,纳米驱油剂iNanoW1.0能够使原来不能建立水驱驱替关系的低渗透岩心 可以建立驱替关系,有利于低渗油层的开发。

    Abstract:

    According to the development demand of low-permeability reservoir in Xinjiang oilfield,the performance evaluation of nano displacement agent iNanoW1.0 was studied by conventional measurements of the surface/interfacial tension,wettability,clay expansion and core displacement experiment. The results showed that the surface/interfacial tension and wettability of nano displacement agent iNanoW1.0 were similar to that of water. The capillary rising height experiment showed that,iNanoW1.0 could reduce the interaction between water molecules and reduce the starting pressure. iNanoW1.0 could improve the anti-swelling effect of clay swelling inbibitor,which was helpful for the development of water sensitive reservoir. Core experiments showed that the nano oil displacement agent iNanoW1.0 could realize the permeability of water in low permeability core,while water without nano oil displacement agent could not pass through the core.
