摘　　要：鲁克沁中区深层稠油采用常规注水开发后因油水黏度比大，平面、剖面注采矛盾严重，注入水单向突进十分严重。采用分层系开发、分层系注水、精细注水、化学调剖等开发对策，平面和剖面矛盾不断改善，水驱动用程度从2008年的17．1％提高到目前的40．9％，地层压力逐年恢复，自然递减得到有效控制。研究表明，由于油水黏度比高，见水后流度比即大于1，而且随着含水上升，流度比上升迅速，注入水的指进、突进会更严重；水驱见效区半径为100-300m，见水前缘与水淹前缘的距离为10-30m．单井及油田水驱特征均表现为凸型，中高含水期为主要采油期。Lukeqin deep heavy oil reservoir was developed by conventional waterflooding process. Because of high oil/water viscosity ratio, ohvious plane and section injection/production contradiction, and water breakthrough was very serious. After using the separated zone devel-opment, separated zone water injection, fine water injection and chemical profile control techniques, the plane and section injection/produc-tion contradiction has been improved, the waterflood producing degree has been increased from 17.1% in 2008 to 40.9% nowadays, the res-ervoir pressure has heen recovering year by year, and the natural decline rate has been controlled effectively. The mechanism study showed that because of high oil/water viscosity ratio, the mobility ratio was greater than one after water breakthrough. As the water cut increasing, the mobility ratio was raised fast, thus the injected water fingering and breakthrough would be more serious. The study shows that the water-flood response radius is about 100-300 meters. The distance between water breakthrough front and flooded front is about 10-30 meters. The characteristics of water drive of single well or oilfield appear in convex. Medium-high water cut stage is its main production stage.
