生物地层学测井资料与地震资料相互综合后,为应用层序地层学详细研究油气勘探区的构造和地质相提供了一种系统的方法。本文讨论了一个实例,在10—60Hz地震资料绘制的构造上钻了若干口井,结果钻遇产层砂岩厚度变化不均的不连续砂体,然后用一个较密的测网采集了高分辨率地震资料(10—100Hz).揭示了过去曾一度认为是浊积砂的地层体的存在。但是该区复杂的地质问题只有在层序地层技术绘制的成果图上才得到详尽的解决。
After the integration of biostratigraphy and seismic data, it provides a systematic method for studying the structure and geological facies of oil and gas exploration area in detail by using sequence stratigraphy. In this paper, we discuss an example where several wells were drilled in a 10-60 Hz seismic data structure and were then drilled into a discontinuous sand body with varying thickness of sandstone in the pay zone. A dense grid was then used to acquire high resolution Seismic data (10-100 Hz) reveal the existence of a formation that was once thought to be turbid sand. However, the complex geological problems in the area can only be solved in detail on the result maps drawn by sequence stratigraphic techniques.
