Abstract: By the research of the relationship among point-number, covering time, point-time of per length and per area, the ratio of onetime to full-time and engineering investment, it is suggested that the decrease of engineering workload—point-time in data acquisition is the key measure to increase the benefit of seismic exploration; cutting down of survey workload in seismic engineering and the drilling footages might be another methods to uplift the benefit of seismic exploration. With the rapid development of seismic equipments, the covering time becomesmore and more, when covering time reaches certain number, additional area would be regarded as the exploration area, and then point-time can be reduced, which is also a measure to raise the benefit of seismic exploration.
