储层综合描述技术在江苏XWZ地区复杂断块群的应用

Application of comprehensive reservoir description technique to complicated fault blocks in Jiangsu XWZ area.

针对江苏XWZ地区复杂断块群的特点,本文以分步优化地震反演为技术手段,综合利用地震、钻井、测井等资料提出了描述油气储层特征八项参数(即砂岩厚度、渗透性砂岩厚度、砂岩有效厚度、孔隙率、渗透率、地层压力、流体势、油水边界)的方法,建立了一套适合复杂断块区的储层综合描述技术。经后续开发井证实。

To cope with complicated fault blocks in Jiangsu province, the comprehensive reservoir description technique that involves 8 parameters (sandstone thickness, permeable sandstone thickness, effective sandstone thickness, porosity, permeability, formation pressure, fluid potential and oil water boundary) has been developed by gradually optimizing seismic inversion and using multiple materials (seismic data, drilling data, logging data and so on). Oil development has shown that this technique has quite high prediction accuracy.
