聚合物注入如今已成为一种成熟的提高采收率的工艺，目前全球范围内正在进行大规模扩建，同时新项目也正在设计中。一些从业者主张注入非常高的粘度，而另一些人则持相反观点。本文解释了为什么聚合物粘度的选择问题至今仍未得到明确的答案，并通过案例研究描述了这两种观点的论据。
本文全面回顾了作者在各种场景和背景下探索注入聚合物粘度问题的全球项目。由于对这些研究的回顾较为详细，本文未收录这部分内容（占全文的主体）；相反，本文作者的讨论和结论将保留并收录在本概要中。
Polymer injection is now a mature enhanced-oil-recovery process, and numerous large-scale expansions are currently underway while new projects are being designed globally. Some practitioners advocate injecting very high viscosities, while others advocate the opposite. The paper explains why the question of polymer-viscosity selection remains without a clear answer and describes the arguments of both positions using case studies.
The complete paper is a comprehensive review of global projects in which the issue of injected-polymer viscosity has been explored by the author in a variety of scenarios and contexts. Because of the detailed nature of the review of these studies, this portion of the paper, which makes up its majority, is not included here; instead, the discussion and conclusions reached by this paper’s author are preserved and included in this synopsis.
