利用Walkaway-VSP技术精细刻画火山岩形态
|
摘要
常规地震资料难以满足火山岩精细解释的需要。通过对吐哈油田三塘湖盆地M68井的Walkaway-VSP资料的精细处理和解释,利用高分辨率、高保真度的Walkaway-VSP纵波成像对M68井区火山岩进行了精细刻画,在纵向上精细识别了火山岩储层和源岩储层的岩性界面,在横向上精细刻画了火山岩的形态和展布范围,取得了良好的应用效果。
It is always very difficult to interpret volcanic rocks on conventional seismic data.So we try to describe volcanic rocks on walkaway VSP data.We demonstrate in this paper an application example in Santanghu Basin,Tuha Oilfield.A walkaway VSP survey was conducted in the Well M68 area,the walkaway VSP data was properly processed,and high-resolution and high-fidelity walkaway VSP Pwave imaging was achieved.Based on this data,volcanic rocks are exactly characterized,and vertical lithologic interfaces of both volcanic rock reservoirs and source rock reservoirs are carefully identified.The horizontal shape and distribution of volcanic rocks are also identified.Our volcanic rock morphology characterization is proved by the latter well drilling.
