摘　　要：新庄油田南三块窄条带状边水稠油油藏热采水平井生产过程中存在油层剖面动用不均、边水侵入等问题。通过从油藏、注采参数和工艺等方面研究了影响水平井开发效果的主要因素,确定并实施了注采参数优化、氮气泡沫调剖、优化注汽管柱等配套技术,改善了稠油热采水平井开发效果,提高了稠油油藏资源利用率,为其他油田同类型稠油水平井开发提供了借鉴。There existed some problems of uneven producing profile and invasion of edge water in the narrow bended heavy oil reservoirs with edge water in horizontal wells with thermal production in Block Nan 3 of Xinzhuang Oilfield.In consideration of reservoir condition,the injection-production parameter and production technology,the main factors that effected the development effect of horizontal wells were studied,the matching techniques are used such as optimization of injection-production parameters,profile control with nitrogen foam,optimization of steam injection casingstring.Through above methods,the producing effect of horizontal wells and the resource utilization in heavy oil reservoirs are improved,and it provides a reference for horizontal well production in similar heavy oil reservoirs.
