摘　　要：国内页岩气的研究已开展多年,页岩气地球物理预测与评价技术也逐步完善。通过几年的技术攻关和在川南地区海相页岩气的勘探开发实践,基本建立了完整的地球物理技术体系,主要包括:地震资料目标精细处理、页岩气测井综合评价与储层特征分析、构造及地震地层解释、地球物理反演及目标预测、页岩裂缝预测、含气性检测、页岩保存条件分析等方面。通过部分技术在川南某地龙马溪组页岩气勘探开发中的应用,展示了页岩气地球物理技术的重要作用。The research of shale-gas has been carried out of many years in China,and the geophysical tech-nology of shale-gas prediction and evaluation has been gradually improved.Through several years of technical research and exploration&development practice,a complete system of geophysical technology is set up,including:seismic data garget fine processing,shale gas logging comprehensive evaluation and reservoir characteristics analysis,structural and seismic stratigraphic interpretation,geophysical inversion and target prediction,shale fracture prediction,gas detection,shale preservation conditions analysis.Through the application of some technologies in the shale gas exploration and development of Longmaxi formation in south Sichuan,the important role of shale gas geophysical technology is demonstrated.
