摘　　要：地面三维地震勘探和井中VSP测井技术都是相对成熟的勘探技术,两者结合起来形成的井地联合3D-VSP勘探技术,是一项新型的地震勘探方法,它实现了地面三维地震采集与井中VSP采集的有机结合。通过对井地联合3D-VSP采集设计、论证思路、方法以及井地联合3D-VSP采集资料频谱、信噪比与波场等效果的分析,认为该方法有效的提高了地震剖面的解释精度,为落实构造、扩大和发现新的圈闭、确定油藏类型、油气开发评价等提供依据,在泌阳凹陷深凹区应用该方法,取得了较好的地质效果。The 3D seismic exploration and VSP are both relatively mature exploration technique, while the 3D- VSP is a new seismic exploration method, which integrates 3D seismic acquisition and VSP. Through the effective analysis of its data- gathering design and approach, frequency spectrum, signal - to - noise ratio and wave field, the precision of seismic section is effectively improved. In this way, it provides foundation for confirming structure, enlarging and finding traps, defining reservoir types and hydrocarbon development evaluation. Good geological effectiveness has been acquired through the application in Biyang sag.
