伊朗Y油田直井轻质油酸化研究及实例

摘要

基质酸化是碳酸盐岩油气藏增产的重要手段.伊朗Y油田为轻质油油田,主力产层F油组是孔隙-裂缝型低渗中孔碳酸盐岩储层高温高压高硫化氢,生产过程中沥青质析出、沉淀和堵塞井筒的现象很严重,F15井成功实施了酸化作业.%Matrix acidizing is an important means of carbonate reservoir stimulation.Y oilfield is light oilfield,reservoir F is the main pay zone of pore-fracture in low permeability carbonate reservoir,and the reservoir F is high pressure,high temperature,high H2S content. Production shows that asphaltene precipitation,and plugging wellbore phenomenon are very serious during production.l acidizing on F15 well was carried successfully.
