三维井地联合Walkaway VSP技术及其在泌阳凹陷的应用
|
摘要
介绍了一种新的地震勘探技术——三维井地联合Walkaway VSP技术,该技术将三维地震勘探技术和VSP技术有机结合,实现了地面三维地震采集和井下VSP技术联合同步采集,发挥了两种技术的优势,弥补了各自的不足,可应用于油气藏的精细勘探和开发。简述了三维井地联合Walkaway VSP技术野外资料的联合采集,分析对比了Walkaway VSP技术与常规VSP技术、地面三维地震的特点,探讨了利用三维井地联合Walkaway VSP技术进行资料处理、联合精细解释的方法,并以泌阳凹陷赵51井区为例对取得的资料进行了精细的联合解释。该方法可提高地震剖面的分辨率、解释精度和标定精度,为落实构造、发现新的圈闭和确定油藏类型以及进行油藏描述、油气勘探开发评价等提供可靠的依据。
This paper introduces a new seismic exploration method3D Walkaway VSP.As a combination of the 3D seismic exploration method and the VSP technology,it can accomplish the simultaneous data acquisition used to performed by the two methods and so it is fully competent in refined petroleum exploration.After the analysis of the characteristics of simultaneous field data acquisition of the 3D Walkaway VSP technology and comparison with the traditional VSP technologies,the paper discusses the integrated interpretation carried out for the data processing and interpretation.The gathered data from the Zhao 51 borehole of Biyang Depression were elaborately deciphered to demonstrate its availability.It is concluded that the new method can provide strong evidence for finding new traps,determining the reservoir type and describing reservoir,and in exploration appraisal,it can greatly enhance seismic profile resolution and calibration accuracy.
