在小口径金刚石钻进中,已成功地使用了乳化液洗井,有效地减弱了钻具的振动,减少了钻头、管材、岩心的磨损,实现了高转速钻进,从而较好地发挥了金刚石钻进的优越性。目前广泛使用的几种乳化剂,属离子分散型,其功能建立在生成具有化学极性的离子基础上,不可避免地存在一个问题,即由于岩石化学成分的不同,使乳化液中的分散离子失去极性而沉淀—破乳。如果不用化学分散的方法,而是使用物理分散的方法来制备乳化液,能否满足钻进工艺的要求呢?
In the small diameter diamond drilling, the emulsion washing well has been successfully used to effectively weaken the vibration of the drilling tool, reduce the wear of the drill bit, the pipe and the core, and achieve the high-speed drilling so as to play a better role Advantages of diamond drilling. Currently widely used several emulsifiers, is an ion dispersion type, its function is based on the generation of ions with chemical polarity, there is inevitably a problem that due to the different rock chemical composition, the emulsion dispersed ions Loss of polarity and precipitation - demulsification. If you do not use chemical dispersion method, but the use of physical dispersion method to prepare the emulsion, can meet the drilling requirements?
