油田开发要求开发地震视频率必须达到150~170Hz,目前距离这个标准相差很远。本文通过研究松辽盆地第四系对地震反射波的吸收过程后,认为造成这种差距的主要原因是第四系近地表层和第四系深层对高频成份的吸收,开发地震激发点和接收点都不能安置在这些层位中,至少不能安置于近地表层中,采集频率才可能大幅度提高。
Oilfield development requires the development of seismic video rates must reach 150 ~ 170Hz, currently far from this standard. After studying the absorption process of seismic reflection waves in the Quaternary of Songliao Basin, the main reason for this gap is the absorption of high-frequency components in Quaternary facies and Quaternary reservoirs, the development of seismic excitation points and Receiving points can not be placed in these horizons, at least not placed in the surface layer, the collection frequency is likely to significantly increase.
