本发明叙述了一种油色酸的乳化液及用这种乳化液处理地层的方法。本发明是一种改进的油色酸酸化乳化液及使用这种乳化液的酸化方法·为了增加酸和地层的正常反应时间,上述乳化液含C8-C18伯胺(作为阳离子表面活性剂)的有效数量最少是一个·为使乳化液在为地层的酸化能力基本耗完后(即变成了废酸)而破乳,本发明配方和方法的改进体现在乳化液含有效数量的非离子表面活性剂,其非
The present invention describes an emulsion of an oil acid and a method of treating the formation with such an emulsion. The present invention is an improved oil acidified emulsion and an acidification method using the same. In order to increase the normal reaction time of the acid and the formation, the emulsion contains a C8-C18 primary amine (as a cationic surfactant) The effective amount is at least one. In order for the emulsion to demulsify after the acidification capacity of the formation has been substantially depleted (ie, turned into waste acid), improvements in formulations and methods of the present invention are reflected in the fact that the emulsion contains a significant amount of non-ionic surface Active agent, its non
