一种高效破乳剂在南海某高含水油田的应用
|
摘要
针对南海某高含水油田采用进口破乳剂和清水剂存在药剂用量大、易堵塞问题,选择不同含水率油水样开展破乳剂主剂、清水组分评价和效果验证,确定了高效破乳剂P-33配方。通过现场试验,破乳剂P-33成功取代进口破乳剂+清水剂组合,在总用量减少95 L/d、费用降幅达50%条件下,外排水水含油均值从14 mg/L降至12 mg/L,外输原油含水稳定在0.4%。
There existed challenging problems in one of the high water content oilfield in South China Sea such as high dosage of imported demulsifier and water clarifier, and easy to be plugged, an efficient demulsifier P-33's formulation was developed through demulsification capability evaluation of the main component, water-clearing component and the final formulation using oil samples of different water content. After P-33's application, the OIW in outer drainage site were decreased from average 14 mg/L to 12 mg/L, and the BS&W in output crude were kept stable at 0.4 % even if the dose was reduced 95 L/d and the cost decreased by 50 %.
