地震仪器和野外采集技术的发展加上新的处理和解释技术已大大地缩短了采集的时间,降低了单元采集费用。同时,由于我们要寻找更加隐蔽的有利地区,以及我们的分析技术变得更先进,因此,需要从地震数据中获取更多的细节。只是简单地寻找构造圈闭的日子几乎在每个探区都已成为历史。现在,我们用地震属性来圈定储层带、计算产层厚度、确定沉积环境,并预测有关储层岩性和流体成分的详细情况。

The development of seismic instrumentation and field acquisition technology coupled with new processing and interpretation techniques has greatly reduced the acquisition time and the cost of unit acquisition. At the same time, more detail needs to be extracted from the seismic data as we look for more subtle and favorable areas and our analytic technology becomes more advanced. Just simply looking for traps to construct days has become history in almost every prospect. Now we use seismic attributes to delineate reservoir zones, calculate production thickness, determine depositional environments, and predict details about reservoir lithology and fluid composition.
