【 摘 要 】

One of the main problems in the development of the new near-zero-offset method based on the roll-along zero-offset receiver (RAZOR) array is how to simulate this spatially extended array. In this thesis we use Sierra products (standard industry geophysical processing and geological interpretation systems) to carry out numerical experiments on synthetic RAZOR array surveys. Two array design modes are proposed for modelling these surveys. The first is the crooked line mode, which is suitable for experiments with a single RAZOR array. Its advantage is that all the data traces are sorted in the order of acquisition of the RAZOR shot gather directly, and are stored in one disk file without any extra processing. The second method is the five-line mode, which is more suitable for simulating roll-along experiments of the RAZOR array. A new Fortran-77 program RAZORSORT.F is developed for post-raytracing sorting. In addition a new quick display tool QPLOT.F has been developed, supported by the UNIRAS package.
