摘　　要：胜坨油田历经三十多年的开发已进入特高含水开发期 ,平面层间高度水淹 ,层内油层底部水窜严重。为挖掘油层层内剩余油潜力 ,运用精细油藏描述技术 ,对胜坨油田各种沉积类型剩余油分布特点进行了综合研究 ,进一步认识了油层层内厚油层剩余油分布规律 ;利用超细水泥堵炮眼工艺进行层内挖潜 ,取得了明显的增油降水效果 ,改善了特高含水期厚油层开发效果。层内挖潜是提高油田最终采收率的有效途径。Shengtuo oilfield has entered extra high water?cut period going through more than 30 years of development with highly watered?out areal interlayer and serious water channeling at the bottom of oil?bearing formations. In order to tap the potential of residual oil in place, distribution characteristics of it in different sedimentary types in Shengtuo oilfield are studied comprehensively using the technology of delicate reservoir description. The distribution rule of residual oil in thick oil?bearing formations is known further. Obvious effect of increasing oil and decreasing water production is achieved by perforation shutoff technology with super?fine cement to tap interlayer potential. Development effect of thick oil?bearing formations in extra high water?cut period is improved. Tapping interlayer potential is the effective way for improving ultimate recovery factor.
