Techniques for Mesozoic-Paleozoic Seismic Data Acquization

It was very difficult for collecting Mesozoic-Paleozoic seismic data,methods for Mesozoic- Paleozoic seismic data acquisition have been researched and developed for years. Because in Mesozoic-Paleozoic strata there existed complex downhole conditions,excitation and receiving conditions were poor,therefore signal-noise ratio was low in data acquisition with poor quality. On the basis of analyzing causes of influencing the data quality,the effects of the methods for Mesozoic-Paleozoic seismic data acquisition are studied,shot intervals its array length,coverage and way of wide-line data acquisition on the imaging and signal-noise ratio in Mesozoic-Paleozoic strata are analyzed.
