SHALLOW FORMATION BRIGHT SPOT AND GAS EXPLORATION
北大港构造浅层地震亮点与天然气勘探

There are many successful examples on applying the seismic bright spot reflection to make a direct detection for the gas reservoir both domestic and abroad, and this has really brought good exploration benefit. However, with the complicated underground situation the bright spot exploration once failed even in such a mature area for bright spot exploration like Gulf Mexico. In the author's opinion whether an oil and gas field can be conducted with reservoir seismic detection mainly dues to the vertical sequence petrophysical characteristics of the target bed, burying depth and the quality of seismic data,etc. On the basis of a thorough discussion on the vertical sequence petrophysical characteristics of Beidagang shallow formations, guided by the seismic geological model of this target area, the bright spot seismic reflection is used to detect the gas reservoir directly, relative great applying effects have been made especially for the area with highly qualified seismic data.
