用“点次”取代地震单位成本的“千米”与“平方千米”

Use of “Point-Times” to Replace “Kilometer” and “Square Kilometer” for Seismic Unit Cost

石油系统目前在地震成本的投资与成本对比方面,使用的千米与平方千米这个计价单位,反映不出单位长度或面积中数据点的多少及每个点接收数据次数的多少,即反映不出地震勘探的工程量。提出把地震勘探中数据点个数与每个点接收数据的次数称为地震工程的工程量,其计价单位为“点次”;讨论单位长度或面积中“点次”的计算、点次与单位造价变化的关系,以及具体工程中地震工程量的计算。

As for the comparison of investment and cost in the seismic exploration of the current oil department, the use of the cost unit like kilometer and square kilometer cannot reflect the unit length or how many data points the unit area has or how many times each point receives the data, namely unable to reflect the engineering workload of seismic exploration. The data points and the times each point receives the data in the seismic exploration are raised as the engineering workload for the seismic project. The cost-calculating unit is “point-time.” This article discusses calculation of unit length and the “point-time” in the unit area, the relations between the point-time and the unit cost variation as well as calculation of the seismic engineering workload in the concrete project.
