摘　　要：从处理角度来说,中、长波长静校正精度是影响石南地区低幅度目标解释可靠性的主要因素之一。因受应用条件限制,各常规静校正方法所得结果较难满足低幅构造识别要求,且不同静校正方法所得中长波长形态差异较大。为此开展的基于井控标定与校正的静校正技术综合应用研究,是利用微测井成果、探井分层数据进行约束反演、质控标定与校正,保证静校正中、长波长量空间变化准确可靠。该方法能使最终静校正量误差控制在3 ms以内,基本能满足石南低幅目标区的地质综合研究需要,对其它探区静校正方法的综合应用也具有一定的借鉴意义。From the perspective of seismic data processing,the accuracy of medium-long wave length static correction is one of the main factors affecting the reliability of low-amplitude targets in Shinan area.Due to the limitation of application conditions,the results obtained by conventional static correction methods are difficult to meet the requirements of low-amplitude structural identification,and the medium-long wave length shapes obtained by different static correction methods are quite different.For this purpose,the comprehensive application research of static correction technology based on well control calibration and correction is to utilize micro-logging results and exploratory well layered data for constrained inversion,quality control calibration and correction to ensure the accuracy and reliability of spatial variation of medium-long wave length in static correction.This method can control the final static correction error within 3 ms,which can basically meet the needs of comprehensive geological research in the low-amplitude target area in Shinan.It also has certain reference significance for the comprehensive application of static correction methods in other exploration areas.
