Abstract:

Layer interpretation is some kind of analysis and processing of seismic data. Aided by the result,geological characteristics can be dynamically shown intuitively. Now,it is an important technology in the process of geological and resource exploration. The effect of interpretation affects the efficiency and success of followup directly. Traditional interpretation methods have lots of drawbacks because of its 2D interpretation approaches based on 3D seismic data,such as low utilization rate of information and rough accuracy.Two new threedimensional interactive layers interpretation methods of profile guidance and data volume guidance are introduced in the paper which compensate for the deficiencies of traditional methods from different aspects. The principle and advantages are analyzed,and at the same time the implementation algorithms and effect pictures are given.
