【摘要】 冀东油田属渤海湾断陷盆地典型的复杂小断块油田,近两年,在大力加强油藏精细描述的基础上,积极推广应用水平井开发新技术,使水平井技术在冀东复杂断块油田开发中的应用规模迅速扩大并取得良好的效果。在水平井开发技术应用过程中,通过不断探索和总结完善,逐步形成了一套适合冀东油田复杂断块油藏特点的水平井应用技术方法,主要包括水平井适应性评价、方案部署、设计、钻井、测井和录井、采油以及生产管理等6个方面14个环节,该技术方法的配套应用既有效地保证了冀东复杂小断块油藏水平井开发技术的应用效果,又为进一步推动水平井技术进步奠定了良好的基础。高尚堡油田浅层南区高63断块多油层小断块层状边底水驱油藏、高尚堡油田浅层北区油藏Ng8小层难采储量的高效开发以及利用小井眼侧钻水平井高效挖潜技术改善老区开发效果的实践验证了该方法的有效性。图2参8更多还原

【Abstract】 Jidong Oilfield is a complex small-fault-block reservoir in the fault basin of Bohai Bay.On the basis of the fine description of the reservoir,the newly developed horizontal well technique is generalized and applied with the application scale speedily extending and satisfactory achievements.A series of techniques suitable for the features of the reservoir are formed,including adaptable evaluation of horizontal wells,scheme deployment,design,drilling,well logging,borehole log,oil production and production management etc.The utilization of the complete techniques ensures the result of the horizontal well development technique in Jidong Oilfield and paves the way for its further advancement.The workability of the method is proved by the reservoir with multi-reservoir,small fault-block,bedded edge-bottom waterflood in Gao 63 fault block of the south area in the shallow formation in Gaoshangpu Oilfield,the highly effective development of the difficult-to-produce reserves in Ng₈ subzone of the reservoir in the north area,and the practice of improving the development efficiency in maturing oilfields by the slim-hole sidetracking horizontal well.更多还原
