摘　　要：为了提升辽河油区海外河油田新海27块的小井距、厚层状常规稠油底水油藏开发效果,在对油藏进行精细描述的基础上,综合应用测井、油藏工程及原井网开发状况、数值模拟等新技术,分析水锥规律和剩余油潜力区。通过优化部署和精心设计与施工的海平2井,充分体现出水平井具有抑制底水锥进,减缓含水上升,增加可采储量,提高采油速度的优点。为水平井技术在类似油藏中的有效应用,探索出宝贵的研究途径和现场实践经验。In order to increase Liaohe Oil Area Haiwaihe Oilfield Xinhai 22 Block dense well spacing and improve heavy bedded heavy crude basal water reservoir exploitation results, based on detailed description to the reservoir, we analyzed the water coning and oil remaining potential area with new technologies including well logging, reservoir engineering, original well network exploitation status, numerical modeling, etc. Through optimized disposition and elaborate design and construction, the Haiping 2 Well fully embodies the excellence of horizontal well, including restraining bottom water coning, decreasing containing water ascending speed, increasing recoverable reserves and improve oil production rate. It explores valuable research approaches and practice experience on site for efficient application of horizontal well technologies in similar reservoirs.
