摘要： 由于胜北地区地震速度横向畸变大,致使局部构造难以落实,导致探井失利。为此,对该区做了基于模型的三维叠前深度偏移处理,以期解决速度问题,落实局部构造。总结了处理及建模的技术思路,对处理中的关键技术做了具体阐述,并对处理成果做了三维解释论证。本次综合研究方法,可以成为进一步作好三维叠前深度偏移处理与解释工作的有益参考,解释成果可以作为扩大该区油气储量规模的依据。

Abstract: Because areal series distribution were found in seismic velocity from Shengbei area(Turpan-Hami basin),local structures were difficult to be clarified in two exploratory wells.3D prestack depth migration processing was then made based on geological model to solve the problem. This paper reviewed the migration processing and related modeldevelopment,including some key techniques applied in processing and 3D interpretation demonstration. These tech-niques and interpretation results can be as guide for the processing in the future and provide favorable objectives for ex-panding petroleum reserves scale in this area.
