黄河三角洲表层岩土介质对地震激发频率的影响
INFLUENCE OF HUANGHE RIVER DELTA SURFACE ROCK AND SOIL MEDIUM ON SEISMIC EXCITATION FREQUENCY
【摘要】 黄河三角洲冲积平原覆盖区是胜利油田油气生产的主要区域,随着勘探工作主要由构造勘探转向岩性勘探,由寻找大油气藏到中小型、隐蔽性油气藏,以及各种砂体,这对地震资料的分辨率提出了更高的要求。提高地震波的激发频率是提高分辨率的重要手段,在表层复杂地区如何选取好的激发介质来提高激发频率尤为重要,我们选取时要全面考虑各种因素的影响程度,才能够科学的选取激发条件。
【Abstract】 The overlay region of Yellow River Delta alluvial plain is the main oil-gas production region of Shengli Oilfield.With the prospect trend changing from tectonic exploration to lithologic exploration, from searching large reservoirs to middle-small scale reservoirs,subtle reservoirs and various types of sandbodies reservoirs,higher resolution seismic data are needed.To improve the seismic wave excitation frequency is an important means of improving resolution,how to select better excitation medium in surface complex area is particularly important,which demands a comprehensive consideration of the impact degree of various factors.
