摘　　要：主要阐述了对淮南煤田东2孔VSP测井资料进行处理、解释的初步成果及其在煤矿采区三维地震勘探中的应用 在处理过程中使用了三分量数据重定向与合成,波场分离,分离后的上、下行P波进行反褶积,零井源距VSP走廊叠加等技术,将处理速度、走廊叠加剖面用于煤田的层位标定,用转换横波速度对3D3C的PSV横波走时信息进行整理和推算,取得了较好的效果。In this paper, it clarified the preliminary achievements of processing and interpretation on log materials of East 2 VSP in Huainan coalfield, and also discussed the application of the achievements in 3D seismic prospecting in the coalfield. In the course of processing, by means of the techniques of reorientation and synthesis to tricomponent data, wave field separation, deconvolution of up and down Pwave, and VSP stack of zero distance for well resource, etc., it gets better effect that the process velocity and the stack section of aisle are applied to coalfield layer marking, travel time information of transverse wave of multiwave and multicomponent PSV is settled and calculated by converting shear wave velocity. Therefore the achievements will plays instructing role in multiwave exploration of coalfield.
