摘　　要：NH区块位于苏北盆地溱潼凹陷西部单斜构造的西北部,2015年获得商业发现。面对国际油价持续低迷,安全环保要求持续提高,勘探开发建设征地难度持续加大等多方面的严峻挑战,采取常规思路开展新区产能建设和开发管理难以实现效益开发和可持续发展。在NH区块开展先导试验,以丛式井开发为核心,通过协作机制高效化、研究应用平台一体化、产建方案集约化和生产管理信息化,形成了适合苏北特色的高效开发模式。实践表明,该模式在改善开发效果,提高生产效率及开发效益等方面应用效果显著,区块日产量较方案设计提高12.7%,与常规建产模式相比,单井建井周期缩短4.6 d,总投资降低28%,运行成本节约520万元/年。The NH Block is in the northwestern part of the western monoclinic structure in the Qintong Sag,Subei Basin,and was commercially discovered in 2015.Facing severe challenges such as the continued sluggish international oil prices,the continuous increase in safety and environmental protection requirements,and the increasing difficulty of land acquisition for exploration and development,it is difficult to achieve effective and sustainable development by adopting conventional ideas for capacity construction and development management in new areas.The pilot tests were carried out in the NH Block,with cluster well development as the core,through efficient collaboration mechanism,integration of research and application platforms,intensification of production and construction plans,and informatization of production management,forming an efficient development model suitable for northern Jiangsu.The practice has shown that this model has significant application effects in aspects of improving development effect,production efficiency,and development benefits.The daily output of the block was 12.7%higher than that of the plan design.Compared with the conventional production model,the single-well construction period was shortened by 4.6 days,the total investment was reduced by 28%,and the operating cost was saved by 5.2 million Yuan/year.
