【摘要】 利用地震叠前各向异性裂缝预测技术,对PG地区西南部须家河组储层裂缝进行预测。研究及预测结果表明:须家河组主要受燕山期、喜山期两期构造运动影响,形成了北东向、北西向断裂带;断层末端及交汇处应力较为集中,有利于裂缝发育;采用P波各向异性检测技术能够较好的预测裂缝发育带。更多还原

【Abstract】 The fracture of Xujiahe formation in southwestern PG block is predicted with Pre-stack Seismic anisotropy for prediction. The research and prediction results show that fault zones of north-east, north-east are formed in Xujiahe formation by tectonic movement of Yanshan and Xishan. The stress in ends and confluences of faults are concentrated, which is in favor of the growth of faults. P wave anisotropy detection can be applied in this formation to predict fracture-developed zone.更多还原
