【摘要】 三维VSP技术能够解决井旁空间的地质问题,得到有关油藏描述方面有价值的信息。三维VSP和三维地面地震进行同步采集具有较高的应用价值,这种联合勘探能够探索最优化勘探目标,解决井周三维精细成像、地震属性和各向异性问题。时移三维VSP相对于地面四维地震来说,采集周期短、费用少、处理迅速、且可以重复用于油藏,应用于确定最佳井位,优化某特定区域的油藏特性,监测流体运动及减少新生产设备的投资风险。三维VSP技术具有广阔的应用前景。更多还原

【Abstract】 3-D VSP technology can be used to solve the geologic problems nearby a borehole,and to extract valuable information about a reservoir.The data obtained by synchronizing 3-D VSP and surface seismic acquisition are of great application value,and can be utilizing to optimize survey targets,images the detailed 3-D geology nearby boreholes,and study seismic attributes and anisotropic problems.Compared to surface time-lapse seismic,time-lapse 3-D VSP is short in acquisition time,cheap,and easy-to-processing,and it is superior in repeated reservoir characterization,determination of optimal well position,calculation of reservoir properties in certain areas,monitoring fluid flow,and reduction of risk in equipment investment.This paper reviewed the applications of 3-D VSP technology and outlooked its future trend.更多还原
