【摘要】 辽河盆地东部凸起勘探程度较低,钻井资料较缺乏,但地震资料相对较丰富。为了能在有限的资料中发掘更多能反映二叠系砂岩分布情况的信息,借助于地震处理中的速度分析资料,利用层速度-砂地比定量解释模型得到二叠系砂地比分布图,并在此基础上对二叠系的有利勘探区带进行了预测。更多还原

【Abstract】 The degree of exploration was low in the east salient of Liaohe Basin,short of drilling data but rich with seismic data in order to explore more data to reflect the distribution of the Permian sandstone,the authors obtained the distribution of Permian sandy ratio with the help of the speed analysis in seismic data processing,the use of quantitative interpretation model of layer velocity-sandy ratio,and based on the above effort,the authors predicted the favorable exploration area in Permian system.更多还原
