Research Progress of Heavy Oil Thermal Recovery Technologies in Shengli Oilfield

针对胜利油田稠油油藏地质特点及开发难点,重点介绍了中深层特超稠油油藏、浅薄层超稠油油藏、敏感性稠油油藏和低渗透稠油油藏等复杂稠油油藏的开发技术,并对其提高采收率机理和现场应用效果进行了总结概括。在此基础上,根据目前研究进展指出了稠油热采开发技术的发展方向,重点介绍了超深层低渗稠油和浅薄层特超稠油的开发技术及其应用。

Aiming at the geological characteristic and development difficulties in the heavy oil reservoirs in Shengli Oilfield, the technologies for developing such complex heavy oil reservoirs as ultra heavy oil reservoir with mid-depth, heavy oil reservoirs with low-depth and thin thickness, water-sensitive heavy oil reservoirs and heavy o reservoirs with low permeability are focused on. Besides, their enhanced oil mechanism and actual performance of field application are summarized. Based on the current research, it is also pointed out that the further development directions of heavy oil thermal recovery technologies are low permeability heavy oil reservoirs with super-depth and ultra heavy oil with low depth and thin thickness
