地震属性分析技术在松辽北徐东地区火山岩裂缝中的应用

Seismic property analysis in the application of the lava crack research at the area of Xudong in Songbei

鉴于深层火山岩裂缝的研究意义重大,探索了应用地震相干与层方位角叠置显示、地震频率体的可视化显示技术,进行火山岩裂缝分析,应用该方法预测了松辽盆地北部徐东地区营城组火山岩裂缝.结果表明该区火山岩断裂存在3个发育带,裂缝走向主要为近南北向、北北西向和北北东向,少量为近东西走向,预测结果与井筒分析结果相符.

Since the research of the deep-seated lava crack is of great significance, this paper tries to probe into the technology of seismic concerned and layer azimuth terracing revealing, the technology of seismic frequency body viewable showing. And it puts forward the analysis ways of lava crack. Applying this method, the paper forecasts that the Yingcheng Team lava crack at the area of Xudong in the north of Songliao Basins generally takes on three grown strips. Its cracks mostly tend towards near to south-north, north-northwest, north-northeast, rarely tend towards near to east-west. Analyzing the outcomes and checkout by way of well drilling canister the forecasting results are essentially correct.
