Beschreibung
Zusammenfassung:	The invention discloses a demulsifier, a treatment method of a straw stalk raw material and application, and belongs to the technical field of oilfield chemicals. The treatment method of the straw stalkcomprises the following steps: reacting the straw stalk raw material with an acid solution according to a material ratio of (1.5-3) g: (100-150) mL, and then filtering and drying. The invention further provides the demulsifier which comprises the straw stalks obtained through the treatment method. In addition, the invention also provides application of the demulsifier in treatment of W/O crude oil emulsion. The demulsifier provided by the invention can realize efficient demulsification in a short time, and the demulsification rate is up to 89% or above. 本发明公开一种破乳剂、稻草秆原料的处理方法和应用，属于油田化学品技术领域。该稻草秆的处理方法，包括将稻草秆原料与酸溶液按照物料比(1.5-3)g:(100-150)mL进行反应，之后过滤干燥即可。本发明还提出一种破乳剂，包括上述处理方法处理得到的稻草秆。此外，本发明还提出一种上述破乳剂在处理W/O原油乳状液中的应用。本发明提出的破乳剂可短时间内实现高效破乳，破乳率高达89％以上。
