地震资料极性判别技术在储层预测中的应用
|
摘要
在储层地震属性预测技术研究方面,过去人们关注的焦点主要集中于地震关键面时窗选取、地震属性选择和地震属性优化及融合等方面,很少注意到地震资料极性对储层预测效果的影响。实际应用表明,地震资料的极性判断错误,可能导致储层地震属性预测失败。针对这些问题,文章在论述如何判别地震极性的基础上,利用地震属性技术对渤海海域某构造储层的横向展布进行预测,取得了较好的效果。
Current research on seismic attributes of reservoir prediction was most focused on the selection of seismic horizon time window and seismic attributes and optimization of seismic attributes,but paied little attention to the effect of seismic data polarity on reservoir prediction.Actually,making the contrary judgment of seismic data polarity can lead the failure of the reservoir prediction.Aiming at these problems,on the basis of seismic data polarity selection,seismic attribute technology is used to predict lateral distribution of one structure reservoir in Bohai and get good effects.
