摘要
庆城页岩油的高效开发引起了国内外的高度关注,目前国内页岩油开发已形成“三个示范区和长庆庆城一个主产区”的区域格局,庆城油田在“产量领先”到“全面领先”的征程中实现了技术、管理、装备等领域的重大突破。但在开发过程中,部分技术及管理人员未能结合非常规开发特征彻底转变观念,仍习惯运用低渗透油藏的开发模式,思考页岩油开发实践。文章以页岩油高效开发中构建技术体系、探索控降递减及保稳产的有效途径为目的,基于30余口产液剖面测试成果深化渗流规律研究,首创基于累产分析的“分类梳理、主因控制、图版跟踪、数智提效”页岩油水平井生产动态分析方法,系统总结了页岩油水平井水平段渗流规律及油井开发特征。在此基础上,重点围绕如何“重新认识油藏”“重新认识油藏压力”等6项重点开发指标进行了论证,指出了在非常规开发模式下上述指标不同于常规油藏开发的新内涵、新特征,研究成果对庆城页岩油开发规律总结和模式创新具有重要推动作用,同时对国内外同类油藏的高效开发提供借鉴参考。
The development of Qingcheng Shale Oil generated intense interest from home and abroad.Under the situation of"three demonstration areas and one main production area",Qingcheng Oil Field has achieved breakthrough in the realm including technology,administrate,equipment.However,some technicians and administrators still carry the unconventional development by the conventional mind of low permeability reservoir.To establish a technical system,explore effective ways to control decline and ensure stable production in efficient development of shale oil,production profile of more than 30 horizontal wells were studied.Based on classification sorting,primary cause control,chart tracking,and digital intelligence efficiency improvement,dynamic analysis of horizontal wells was created,and flow pattern of horizontal wells was summarized.Based on the above,six important concepts and indexes were discussed.And their new connotation and characteristics were noted,compared with conventional reservoir.The results of this article have an important driving role in summarizing the laws and innovating models to the development of Qingcheng Shale Oil.At the same time,it also has significant reference significance for the development of similar oil reservoirs at home and abroad.
