酸化用消泡剂的研制与应用
|
摘要
油气田酸化施工酸液配制中产生的大量泡沫,自然消泡困难,影响正常施工;碳酸盐岩储层酸化时酸岩反应会产生大量气体,酸化结束后返排液里存大量泡沫,导致酸液的收集和处理困难。针对以上酸化产生的泡沫,使用常用的消泡剂效果差,研制了一种酸化用消泡剂,以端环氧基硅油和聚胺醚M-1000合成的氨基聚醚有机硅、二甲基硅油和白炭黑制备的硅膏为主要成分,以Span-60和Tween-60为乳化剂,以羧甲基纤维素钠为增稠剂,采用高速剪切搅拌的方式进行乳化,得到酸化用消泡剂BH-SPK。BH-SPK与酸液体系配伍性好且性能优异,在加量仅为0.5%情况下,消泡时间仅为36 s,抑泡时间可达3521 s。BH-SPK在艾哈代布油田酸化现场配制转向酸的过程中应用,有效地解决了配酸过程中产生大量泡沫的问题。
In preparing acidizing fluid, large amount of foam is generated in the fluid and is very difficult to defoam, thus affecting the normal process of acidizing operation. In acidizing carbonate reservoirs, reaction between the carbonate rocks and the acid also generates plenty of gas which generates foams in the flowback fluid and is very difficult to collect and dispose. Defoamers are used to defoam the fluid, but the effectiveness is not satisfactory. A defoamer BH-SPK used in acidizing fluids has been developed to address these problems. BH-SPK is formulated with several chemical compounds, such as amino polyether silicone made from end epoxy silicone oil and polyamine ether M-1000, and silicone paste made from dimethyl silicone oil and white carbon black. These two compounds are the main components of the defoamer. Other components include SPAN-60 and TWEEN-60 as emulsifier, and sodium carboxymethylcellulose as viscosifier. BH-SPK is produced by mixing these components at high shear rates. BH-SPK is well compatible with the acids used for acidizing job and has excellent properties. At a concentration of 0.5% BH-SPK, time for defoaming is only 36 s, and time for inhibiting the generation of foam is 3,521 s. BH-SPK has been used in making converting acid in the Al-Ahdab oilfield, effectively resolved the serious foaming problem in formulating acid solution.
