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。
利用地震疊前各嚮異性裂縫預測技術,對PG地區西南部鬚傢河組儲層裂縫進行預測。研究及預測結果錶明:鬚傢河組主要受燕山期、喜山期兩期構造運動影響,形成瞭北東嚮、北西嚮斷裂帶;斷層末耑及交彙處應力較為集中,有利于裂縫髮育;採用P波各嚮異性檢測技術能夠較好的預測裂縫髮育帶。

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.
