Synergistic Effect of Chemical additives and Fracturing Cleanup additives on the solution Interfacial Tension

HE Jing1,WANG Man-Xue2,WANG Ning1,NI Jun1,ZHAN Zhuan-Ying1(1.Yanchang Research Institute of Petroleum Exploration and Development,Yangchang,Xi'an,Shanxi 710075,P R of China;2.College of Chemical Engineering,Xi"an Shiyou University,Xi'an,Shanxi 710065,P R of China)  
At room temperature,the test isopropanol,OP-10,alkyl polyglycosides,fluorocarbon surfactant and salt and other additives to help with the fracturing exclusive agent after the solution of the compound surface tension and interfacial tension by surface tension and the spinning drop ultra low interfacial tension instrument..The results showed that: different chemical additives on the fracture table to help row of agent solution interfacial tension differently.The impact of surface tension is smaller than its interfacial tension,which compared with and without chemical additives compared to 0.4% isopropyl alcohol solution interfacial tension reduction of nearly 60%;0.5% OP-10 on the solution of interfacial tension reduction of 55%;0.3% of the alkyl glycosides to reduce the interfacial tension of the solution,53%;0.005% fluorocarbon interfacial tension of the solution decreased by 76%;inorganic salts on the surface tension has little effect on the interfacial tension impact is significant.
