Abstract

Abstract:

Although the oil-gas resources of southern margin of Junggar Basin are very abundant，geologic condition is so complicated that the quality of seismic data is very bad，signal-to-noise ratio is low，static correction problem is apparent，the difficulty of imaging is big and the precision of structure mapping is poor.For resolving these four big problems，the idea，method and flow on sophisticated structure study in piedmont are put forward in this article.Omnibus key technique is adopted，tackling key problem carried out by integrative study mode of acquisition，emphatic structure target of southern margin （Horgos anticline） processed and interpreted，a set of structure traps which have the value of drilling and offering well site disposition is fulfilled.

Key words: Junggar Basin, static correction, prestack migration, velocity model, structural model building
