AVA处理技术及其在英台—大安地区的应用

AVA processing technique and application in Yingtai-Da'an Area

针对AVA属性分析方法对其处理技术应用时的资料精度要求,以解决AVA资料处理中的关键技术问题为目的,合理利用叠前去噪、振幅补偿、反褶积和静校正等处理技术对英台—大安地区地震资料进行了三维高分辨率的精细处理,强调了相对振幅保持和地表一致性处理在AVA处理中的重要作用。AVA处理方法的开发与应用结果表明,采用该技术并结合模式判别法进行的储层及裂缝预测效果较好,能够为地震、地质研究提供可靠的基础资料,也为今后的井位部署奠定了基础。

Aiming at data accuracy requirelnents generated from AVA property analysis method applying prcessing technique to resolve key technique problems during treatment, by reasonably using several technique including, noise elimination, alnplitude colnpensation, deconvolution, static con＇ection seismic data came from Yingtai-Da＇ an area are developed to finely process 3D high resolution and elnphasize the significance of relative amplitude keeping consistence with surface during AVA processing. The developnlent and application results of AVA processing method it dicated, using this technique associated with mode discrimination to predict reservoirs and fractures can get better effects, and can provide reliable basic data for seismic and geologic research, also establish foundation for future well site deployment.
