页岩气地震地质工程一体化技术的应用
|
摘要
为满足页岩气勘探开发的需求,根据地震资料横向分辨率高、所含信息丰富的优势,探索其在"甜点"预测及综合评价、水平井位设计及优化、钻井跟踪、钻后分析(包括压裂方案设计)等阶段中应用,充分发挥地震资料的优势,落实"甜点"区,部署、优化井位,提高井筒完整性及优质储层钻遇率,进而为提高单井产量奠定基础。
Seismic data is usually now used in the shale gas exploration and development.Sweet spot prediction and evaluation are carried out with its high lateral resolution and rich information.Based on this kind of high-quality seismic data,horizontal well drilling trajectory design and optimization,anddrilling trajectory tracking,after-drilling analysis(including hydro-fracturing design)are conducted.Favorable sweet spot zones are characterized and the well location deployment and optimization are proposed,which provides a solid foundation for a good drilling success rate and good shale gas production.
