Higher seismic imaging exactness is in need as the targets of
exploration and development are becoming more and more
complex. In recent years , prestack time migration technology is
developing rapidly in the big oil field. Because of the Zhongyuan
oilfield being a style fault2block oil & gas field , the complex
subsurface structure impedes the exploratory development.
Imaging exactness have been greatly improved in two years ,
during which applying the prestack time migration to multiple
fault block in Dongpu Depression. At the same time , the
prestack time migration technique has been consummated and the
satisfactory results have been achieved yet which applying it to
other blocks.
