横向预测技术在储层研究中的应用

Application of Jateral prediction in reservoir study,

横向预测是一项新的储层地震技术。利用地震资料进行储层横向预测,是先将地震资料变成可与钻井、测井资料直接对比的形式,然后以岩层为单元进行综合解释。合成声波测井是一种有效的横向预测方法,它把界面型地震反射剖面转换成岩层型测井剖面,用于研究储层的空间展布。应用这套技术在砂岩储层和碳酸盐岩孔隙发育带的研究中已取得明显的效果,为进一步部署钻井提供了依据。

Lateral prediction is a new seismic technique for reservoir study. Lateral reservoir prediction using seismic data needs to make seismic data direct correlative with drilling and logging data, then to comprehensively interpret rock formations. Synthetic sonic logging is an effective lateral prediction technique, it converts seismic reflection section into lithologic logging section so as to investigate reservoir distribution.The application of the technique in studying sandstone reservoir and favourable porosity belt of carbonate formation has resulted in good outcome, and offered evidence for further drilling.
