摘　　要：以三维地质建模为基础的地质工程一体化已经成为非常规油气勘探开发的关键技术。由于松辽盆地古龙页岩油的钻井资料少、数据冗杂,亟需开展基于地震信息约束的三维地质建模技术研究,来满足页岩油藏丛式水平井平台勘探开发需求。根据古龙页岩油为代表的陆相页岩油建模的独特性,以工厂化、集约化的布井思路为指导,充分利用钻井、测井和地震预测数据,开展构造建模、属性建模、裂缝建模和丛式平台井区地质导向技术研究,建立了多信息融合的地震地质工程一体化三维建模技术流程。搭建了智能高效的地震地质一体化技术应用平台,为试验区水平井平台的钻井工程、压裂工程和油藏开发提供全时期的辅助实时指导。一体化应用流程在古龙页岩油试验区取得了较好的应用效果,其中的研究思路可借鉴到其他非常规油气藏。Geoscience and engineering integration based on 3D geological modeling has become key technology for unconventional oil and gas exploration and development. Due to the lack of drilling data and miscellaneous data for Gulong shale oil in Songliao Basin,3D geological modeling technology constrained by seismic data is an urgent challenge to meet the exploration and development needs of cluster horizontal wells platform for continental shale oil. According to the uniqueness of continental shale oil modeling represented by Gulong shale oil,guided by the idea of factory and intensive well deployment,study on structural modeling,attribute modeling,fracture modeling and geosteering technique for cluster platform well block is carried out by making full use of drilling,logging and seismic prediction data,and integrated seismic-geoscience-engineering 3D modeling workflow is established by multi-information fusion. Intelligent and efficient seismic-geoscience integration platform is built to provide fulltime supporting real-time guidance for drilling engineering,fracturing engineering and reservoir development of horizontal well platform in the pilot area. The integration application workflow has achieved much benefit in Gulong shale oil pilot area,and the research idea can be used as reference for other unconventional oil and gas reservoirs.
