提高物探工程投资效益的措施

Measures to Enhance Investment Benefit of Geophysical Engineering

通过研究单位长度和面积的“点数”、覆盖次数、“点次”及一次面积与满次面积比值的大小与工程投资的关系,认为减少资料采集工作中的工程量——点次,是提高地震勘探效益的根本措施;减少地震工程中的测量工程量、钻井进尺是提高地震勘探效益的其他途径。随着地震仪器的发展,覆盖次数越来越高,当覆盖次数达到一定次数后,把一定的附加面积当作勘探面积,从而减少点次,也不失为提高地震勘探效益的又一条措施。

By the research of the relationship among point-number, covering time, point-time of per length and per area, the ratio of one- time 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 becomes more 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.
