摘要

PS剂木质素磺酸碱(简称PS剂)是近年来出现的一种新型表面活性剂,是由废纸液经特殊工艺技术处理提炼而成,物理化学性能稳定,具有降低原油粘度和油水界面张力的特性。用PS剂进行驱替,可提高采收率。通过室内试验、文31断块现场驱替试验和数值模拟分析等研究工作,进一步探讨了PS剂的驱油机理、摸索了注PS剂驱油的现场经验,取得了一定的研究成果和认识。

Abstract

Lignosulfonate(PS) is a new surfactant flooding appearing in recently.It extract and purify from waste liquid of paper made and have stabilization physical chemistry performance.It can reduce the viscosity of oil and the inter facial tension of oil-water.Flooding PS can enhanced oil recover.From laboratory testing,field testing and numerical simulation analysis,the oil displacement mechanism has been researched.The field experience and economic effect have obtained.
