摘　　要：胜利油田罗西区块属深层稠油油藏,具有埋藏深、粘度高、斜度大、易乳化等特点。针对该区块特点,分析研究了深层稠油油藏的开采方式、压裂改造、井筒举升和降粘等配套工艺技术,并进行了现场试验。结果表明:对于低渗透深层稠油油藏采用"先期压裂井筒降粘冷采、后期注蒸汽热采"配套工艺技术具有较好的开发效果,经济效益明显,具有推广价值。Block Luoxi in Shengli Oilfield belonged to heavy oil reservoirs with the characteristics of deep burial,high viscosity,high deviation,and easy emulsification etc.Aiming at characteristics of the block,the auxiliary techniques for deep reservoir production,fracturing reconstruction,wellbore lifting,viscosity reduction were analyzed,and a field test was carried out.Results show that the matching technique of 'cold production by pre-fracturing and well-bore viscosity reduction,thermal production by steam injection' is used in deep buried heavy oil reservoirs with obvious economic benefit and it is wealthy to be popularized in oilfields.
