在识别亮点的要素中,强振幅特征是最重要的,一些在理想情况下得到的其它标志,实际中未必能出现。经过复杂处理过程的亮点剖面与常规地震剖面并无本质的差别,因此,在常规剖面上显示的亮点也可作为提供井位的参考或依据。在主要的含油层系内,综合利用构造高点部位的亮点会取得较好的效果。最后以实例说明,用强振幅这个标志找到了气田,打出了高产油井。

Among the elements that identify the bright spots, the strong amplitude feature is the most important, and some other marks obtained under ideal conditions may not actually appear in practice. The bright-spot profiles that go through the complex process are not fundamentally different from those of conventional seismic profiles and therefore the bright spots displayed on the regular profile can also serve as a reference or basis for providing well locations. In the main oil-bearing formation, the comprehensive utilization of high spots in the structure will produce better results. Finally, an example is given to show that the gas field has been found with the sign of strong amplitude and that a high-yielding oil well has been drilled.
