DX型消泡剂的研制

Development of DX Defoamer

泡沫钻进中，聚集在孔口的废泡沫严重污染了周围环境，影响工人操作。为此研制了属有机硅类型的DX型消泡剂。采用该消泡剂可对废泡沫进行迅速、简便、无新污染的消泡处理。还介绍了消泡剂的种类、选择原则及现场试验。

Abstract In foam drilling, the waste foam which accumulates at the well head seriously contaminates the environment and affects the operation. So, an organic silicon type DX defoamer has been developed, which can eliminate the waste foam quickly and easily, without new contamination. The paper also introduces the types of the defoamers, principle for selection and the field application experiences.
