零偏VSP井资料在地震层位标定中的应用
|
摘要
利用零偏VSP井资料可以精确标定地震层位,从而提高地震解释、储层反演及综合预测精度。地震层位的标定主要依靠零偏VSP井资料所提供的速度参数,通过零偏VSP上行波叠加剖面,走廊叠加剖面和常规地震水平叠加剖面,组成L图进一步标定层位。
The geologic horizon could be accurately calibrated by zero offset-vsp well data.So we can improve the seismic explanation,reservoir inversion and comprehensive prognosis.The geologic horizon calibration mainly relies on velocity parameters which are provided by zero offset-vsp well data.Through the zero offset-vsp uplink-wave stack section,passage stack section and convention seismic horizontal stack section together make up the so-called L chart.
