Accessing Seismic Data by Computer Programming

SU Xin,DU Xin(Department of Computer and Information Engineering,Chengde Petroleum College,Chengde 067000,Hebei,China)  
The seismic data is one of the important data in petroleum exploration and production.Its format is complicated and the data body is huge,and the access to seismic data become one of the difficult technical issues in geophysical software development.Through analysing the common format of seismic data,we can find that the key technique in seismic data accessing is the seismic traces' random location in SEG-Y file.We put forward a method of accessing seismic data on PC,and read the huge body of seismic data directly and access random seismic traces in SEG-Y file.Using this method in seismic data management software,which is included in the technological project multi-discipline experts explore base on virtual reality environment of CNPC,we can access the huge body of seismic data more quickly and exactly.
