高效自组装超分子驱油体系研究

胜利油田化学驱优质资源一、二类油藏储量基本动用完毕，以高温高盐油藏为主的三类储量（油藏温度>85 ℃，矿化度> 30 000 mg/L）将是今后三次采油的主阵地，但在高温高盐油藏实施聚合物驱油的过程中遇到诸如聚合物遇盐降黏、高温水解、高温降解等问题，严重影响了聚合物驱油技术的应用。超分子体系是一种小分子通过分子间的作用力进行自组装的一个分子聚集体系，以超分子工程学及超分子化学理论为基础，通过设计合成三种高效超分子产品及驱油体系，并对合成的超分子体系进行驱油性能评价，实验表明RTS 型超分子体系增黏效果显著、具有良好的耐温抗盐性、对污水有良好的适应性，并且具有优良的老化稳定性，室内物模实验表明具有良好的提高采收率效果，应用前景良好。

Study on Efficient Self-assembly Supramolecular Oil Displacement System

High quality chemical flooding resources of type I and II reservoir reserves have nearly run out in Shengli Oilfiled.Type III reserves with high temperature and high salt reservoirs（reservoir temperature > 85 ℃，salinity > 30 000 mg/L）willbe in the main position in the tertiary oil recovery in the future. But in the implementation of polymer flooding process inhigh temperature and high salt reservoir meets such problem as viscosity reduction after polymer comes across salt，high temperaturehydrolysis，and high temperature degradation，which has a serious impact on polymer flooding technology application.Supramolecular system is a molecular gather system where a small molecules make self-assembly through the intermolecularforce. With super molecular engineering and supramolecular chemistry theory as the foundation，and by synthetizing threekinds of efficient supramolecular products and oil displacement system，are make evaluation of oil displacement performanceof the synthesis of supramolecular system. Experiments show that RTS type supramolecular system viscosifying action effectis remarkable，with good heat and salt resistance，and a good adaptability to sewage，and excellent ageing stability. Indoorphysical model experiments show that it is quite effective in improving oil recovery，and has good application prospect.
