Problems solved by technology

At present, the section extraction algorithm applied to 3D seismic data is mainly based on serial calculation. One of the important reasons is that the storage method of 3D seismic data limits the reading speed of seismic data. The line direction is stored sequentially, and HDFS is used, so the reading efficiency of the transverse survey line and any survey line is not high. In this case, the serial calculation of the profile extraction algorithm is a reasonable way
