摘要
随着长庆油田的迅速发展,在二次采油后期,加强了酸化、压裂、堵水、调剖、聚表二元驱、空气泡沫驱等多种增产稳产的措施,各种化学驱油剂的注入以及粘稠油比例的提高,采出液变得越来越复杂,一些常规破乳剂已不能保障原油脱水系统的平稳运行。本文主要通过实验研究各种措施对原油乳化的影响以及新型高效破乳剂GT-3的研制。
Along with the quick development of Changqing oil field,various appncauon o, stable production are adopted in the secondary oil recovery later stages,such as acidification fracturing, water plugging, profile control, polymer flooding and air foam flooding. Because of Pouring into oil displacement agent and having a high proportion of thick oil ,some con- ventional demulsifying agents can not make sure that crude dehydrating plant set runs steady ,this paper studied the effect of the treating fluid on crude oil emulsion,and a new high-efficiency demulsifying agent GT-3 was developmented by experiment.
