摘要
井震标定是连接地震与地质的桥梁,标定结果的准确程度直接影响构造解释和油藏描述的准确性。在实际工作中,由于工程原因等导致某些井获取的有效声波数据较短且未进行VSP测井,井震标定难以进行。这里系统分析了在这种特殊情况下,用两种常规时深关系进行井震标定存在的问题,并就这一特殊情况下如何高精度完成标定工作和验证标定结果提出了建议。
Well-seismic calibration is a bridge connecting seismic and geology.The accuracy of the calibration has direct impact on the accuracy of structural interpretation and reservoir characterization.In the practical work,engineering causes has resulted in some wells,effective acoustic data are very short and have no chance to VSP logging.This paper systematically analyzes the problem of two conventional time-depth relationships used to calibrate in the particular situation,then gives proposal that how to accurately complete the calibration and verify the calibration results in the particular situation.
