陡坡带复杂地质模型的建立
|
摘要
本文以沉积学、地震地层学等理论为指导,综合应用地质、地震和测井等信息,对济阳拗陷车镇凹陷北部陡坡带砂砾岩扇体进行详细的地震地质相模式研究,并论述了砂砾岩扇体地质模型建立的具体过程和方法,即先根据波阻抗与岩相的关系建立砂砾岩体框架模型,对模型进行速度分析、模型细化和时深转换,最后通过正演模拟得到扇体模型。应用效果表明,这是一套行之有效的复杂地质体建模方法,通过对该区扇体模型的深入研究后认为,该区目的层同相轴中断、分叉、扭曲并非由断层引起,而是岩性变化的结果。
Guided by sedimentology and seismic stratigraphy and integrative application of geologic, seismic and logging information, the paper carried out detailed study of seismic-geologic facies model for sandy-gravel fan on northern steep slope zone of Chezhen sag and talked about the concrete method and process: first the frame model of sandy-gravel body is built up based on the relationship between the wave impedance and lithologic facies, then the velocity analysis, model-fractioned and time-to-depth conversion are carried out for the model and finally the fan is gotten by forward simulation. The application results showed this is a set of feasible model-building method of complex geologic body. It's considered by deep study of fan model in the region that the cutoff, branching and distortion of target events in the region do not result from the fault, but lithologic change.
