In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.

本文通过一系列的实验，合成了两个系列的Gemini型表面活性剂，即双烷撑双季铵盐表面活性剂m-s-m·2Br和双烷撑双季铵盐表面活性剂-s-·2Br，用红外光谱对其结构进行了表征，并且对影响合成双烷撑双季铵盐表面活性剂反应的因素进行了讨论，找出了合成双乙撑双季铵盐表面活性剂m-2-m·2Br的最佳条件：溴代烷与四甲基乙二胺的摩尔比为3.0：1.0，以乙醇作溶剂，在回流温度80℃下反应48小时；合成双烷撑双季铵盐表面活性剂12-s-12·2Br的最佳条件：十二叔胺与1，3-二溴丙烷(1，4-二溴丁烷)摩尔比为2.2：1.0，以乙醇作溶剂，在恒温80℃下回流反应48小时。

Therefore the chapter gives out a method to enhance the oil recovery ------surfactant flooding, choosing firstly non hydronium surfactant compound system that is due to oil permeable bed of Xing-shugang oil field, and measuring relative permeability in surfactant flooding, surfactant flooding has the purpose to reduce oil-water interface intension and add oil disperse in water.

为此本文提出了注活性水提高低渗透油层开发效果的技术方法，优选出适合杏树岗油田低渗透油层条件下的非离子表活剂复配体系，并对活性水驱油时的相对渗透率进行了测定，活性水驱油可以起到降低油水界面张力、增加原油在水中分散的目的。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。
