当生物地层学和测井资料与地震资料进行综合分析时,层序地层学方法为油气远景区地质相和构造的细分提供了一个系统的途径。在本文所讨论的实例中,在用10~60Hz频率地震资料编绘的构造上钻了数口井,这些井均钻遇了厚度不同且不连续的产层砂体。根据后续采集的密网高分辨率地震资料(10~100Hz)显示,怀疑这些地质体是浊积砂岩。但复杂的地质面貌只有通过层序地层学技术的制图才能精确辨识。
When biostratigraphy and well logging data and seismic data are comprehensively analyzed, the sequence stratigraphy method provides a systematic way for the subdivision of the geological facies and structure of the oil and gas prospect. In the examples discussed here, several wells were drilled in constructs plotted with seismic data at frequencies of 10-60 Hz, all of which encountered production sandbodies that differed in thickness and discontinuity. According to the subsequently collected dense-net high-resolution seismic data (10 ~ 100Hz), it is suspected that these geologic bodies are turbidite sandstones. However, complex geological features can only be accurately identified through the mapping of sequence stratigraphic techniques.
