四川盆地地震勘探工程成本浅析

ANALYSIS ON ENGINEERING COST OF SEISMIC EXPLORATION IN SICHUAN BASIN

在四川盆地的地震勘探工程中,地震资料野外采集施工费用,即地震工程预算中的直接工程费,占整个地震勘探工程成本的80%左右。而地震资料野外采集施工参数的选择又很大程度地影响着施工费用。根据该定额的计算办法,从工区类别、覆盖次数、仪器道数、道间距、井深、钻机类型等6个因素对地震勘探工程成本的影响进行了分析,提出降低地震勘探工程成本,需要在地震资料野外采集施工设计中,对施工参数进行的优化设计。

The expense for the field acquisition of seismic data,i.e.the direct cost in the budget of the seismic engineering,accounts for about 80% of the whole engineering cost of seismic exploration.And the selection of the operation parameters for the field acquisition of seismic data influences the expense greatly.According to the calculating method of the quota,the influence of the 6 factors,such as the working zone grade,the coverage times, the channel number of the instrument,the station interval,the hole depth and the rig type,on the engineering cost of seismic exploration is analyzed.It is suggested the optimized design of the operation parameters should be conducted in the working design for the field acquisition of seismic data to decrease the engineering cost of seismic exploration.
