重烷基苯磺酸盐在油田三次采油中的应用探讨

Application of HABS(heavy alkyl benzene sulfonate) in the tertiary oil recovery of oilfi eld

表面活性剂驱是在三次采油技术中应用最多的一种驱油技术,不仅对采收率的提高帮助很大,而且具有较大的发展潜力。随着我国采油技术的不断进步,三元复合驱的应用也得到了推广,在三次采油中经常会用到磺酸盐类表面活性剂,经大庆、胜利等油田的实验,取得了较好的效果。从当前的油价涨幅来看,影响三次采油表面活性剂驱发展的关键在于表面活性剂的成本,因此需要加快对耐高温、耐盐、低成本的表面活性剂体系的研发。本文将在概述油田三次采油的基本情况和重烷基苯磺酸盐的基本化学构成后,对重烷基苯磺酸盐在工业中的应用进行分析探讨,最后进行总结。

Surfactant flooding is the most applied flooding technology in the tertiary oil recovery technique, it is not only a great help to increase the recovery efficiency, and having the further development potential. Along with the continuous improvement of our country oil recovery technique, the application of three compound combination flooding also has been popularized, the sulfonate surfactants is often used in the tertiary oil recovery and got good effect through the experiments in Daqing,Shengli and other oilfields.Seen from the oil price rise at present, the key to influence the development of surfactant flooding is the cost of surfactant, so the research and development of the high temperature resistance,salt tolerance, low cost surfactant are required to speed up.This article analyzes the industrial application of HABS after introduces the basic information of oilfield tertiary oil recovery and the basic chemical composition of HABS, and summarizes in the end.
