油溶性凝析油破乳剂及其制备方法
摘要：
本发明公开了一种油溶性凝析油破乳剂及其制备方法。本发明的凝析油破乳剂是在溶剂中添加交联型嵌段聚醚破乳剂、梳型聚硅氧烷破乳剂和甜菜碱型氟碳表面活性剂而成的复配物，该复配物的重量百分比为交联型嵌段聚醚破乳剂 10～25%，梳型聚硅氧烷破乳剂 5～15%，甜菜碱型氟碳表面活性剂0.05～0.2%，其余为溶剂；其适用于天然气井泡沫排水采气工艺采出液凝析油的回收，能使不同泡沫排水剂形成的凝析油乳液都达到理想的破乳效果，具有常温下破乳速度快和破乳效率高的特点，能保证气田凝析油的高效回收。
摘要（英）：

The invention discloses an oil-soluble condensate oil emulsion breaker and a preparation method thereof. The oil-soluble condensate oil emulsion breaker is a compound formed by adding a cross-linking type block polyether emulsion breaker, a comb-type polysiloxane emulsion breaker and a glycine betaine type fluorocarbon surfactant to a solvent, and the compound comprises the following components in percentage by weight: 10%-25% of the cross-linking type block polyether emulsion breaker, 5%-15% of the comb-type polysiloxane emulsion breaker, 0.05%-0.2% of the glycine betaine type fluorocarbon surfactant and the balance of the solvent. The oil-soluble condensate oil emulsion breaker disclosed by the invention is suitable for the recovery of condensate oil contained in a produced fluid of a natural gas well foaming drainage gas recovery process, can achieve an ideal emulsion breaking effect of an condensate oil emulsion formed from different foaming drainage agents, has the characteristics of high emulsion breaking speed and high emulsion breaking efficiency at normal temperature, and can ensure the high-efficiency recovery of the condensate oil of a gas field.
