摘要
测井数据预处理和横波计算是叠前反演的前提和基础,通过叠前叠后同时反演追踪XY15井区侏罗系三工河组储层,试油结果表明纵横波速度比在识别岩性和含油性方面较波阻抗更为敏感。
The preprocessing of well log data and shear wave calculation are the precondition and base of prestack inversion.We study the Jurassic San Gong He group reservoir bed by simultaneous pre-stack & post stack inversion in XiaYan 15 borefild,the results of test demonstrate that the velocity ratio of compress to shear wave is more sensitive than acoustic impedance on identifying the lithologic character and fluid property.It approve that pre-stack inversion is an effective method on identifying the complex reservoir bed and hydrocarbon bearing interval.
