南堡凹陷北部复杂构造成像技术研究

Study on imaging technology of complex structures in the north of Nanpu Sag

南堡凹陷北部工区断裂系统比较发育,断层较陡,构造比较复杂,构造成像是本次研究的重点。在成像系统中任何好的成像方法都必须基于有一个精确的速度场才会有一个好的成像结果,所以本次研究主要有三方面的工作:精确速度场的求取和建立、叠前时间偏移。

The fault system in the northern work area of the Nanpu Sag is relatively developed,with steep faults and complex structures.Structural imaging is the focus of this research.In the imaging system,any good imaging method must be based on an accurate velocity field to have a good imaging result.Therefore,this research mainly includes three aspects:the acquisition and establishment of the accurate velocity field,and the pre-stack time deviation.shift.
