摘要

室内实验表明,三元复合溶液流经相同分压注入工具,其溶液黏度损失比聚合物流经相同分压注入工具的溶液黏度损失高1倍以上,高黏损会降低三元复合驱整体驱油效果。为弄清两种溶液黏度损失差异,利用扫描电镜和动态激光散射技术手段,对比分析了两种溶液流经分压工具前、后微观分子聚集形态和聚合物分子线团直径。对比结果表明:由于三元复合溶液中碱和表面活性剂的存在,三元复合溶液微观分子聚集形态的网格非常稀疏易破坏,造成流经相同分压工具,三元复合溶液黏度损失较大,此结果对优化化学驱分注工具结构具有理论指导意义。
Laboratory test showed that the viscosity loss of ASP solution was over two times that of polymer solution after flowing through the same separate layer pressure injection tools, which would reduce the overall flooding effect by ASP flooding. To find out the viscosity loss difference between the two kinds of solutions, the comparative analysis of microscopic molecular aggregation morphology and polymer molecular coil diameter has been conducted by using scanning electron microscope and dynamic laser scattering method, before and after the two solutions flowing through the separate layer pressure injection tools. The results indicated that the microscopic molecular aggregation morphology grid of ASP solution was very sparse and easily to be damaged due to the presence of alkali and surfactant, which could cause bigger viscosity loss of the ASP solution when flowing through the same separate layer pressure injection tool. The research results have theoretical significance for optimizing the tool structure in separate layer injection by the chemical flooding.
