摘要
横波数据是叠前地震反演过程中最重要的特征参数之一,在油气藏描述过程中起到关键作用,可以真实地反映地层的岩石性质和流体特征,减少地震预测的多解性。通过建立准噶尔盆地岩石物理数据库,提高了横波质量,扩展了横波的使用范围,使叠前地震反演成为储层识别的常用方法之一。横波质量控制方法适用于预测横波,也适用于不同测井系列的实测横波,可以大大降低油气勘探费用,全面推广叠前地震反演的应用产生的经济效益可观。
The shear wave logging is the most important parameter in prestack inversion,which is the key actionin oil and gas accumulation. It can reflect the character of lithology and fluid of formation correctly and decreasethe ambiguity of forecast. By establishing the petrophysical database in Junggar Basin,we upgrade the quality ofshear wave logging and broaden the usable range,make the general purpose of prestack inversion in reservoir de-lineation. The logging quality control is not only for shear wave loging of series equipment,but for shear wave cal-culation,which is popularized and application of the prestack inversion will generate great benefit.
