【摘要】 地层油藏是一种复杂的油藏类型,在地震描述中根据地震反射特征追踪的尖灭线与实际地层油藏的尖灭线常常存在较大的误差,因此精确落实地层超剥线的位置是地层油藏勘探成功的关键,本文通过大量的正演模型和地质统计方法,发现地层油藏超剥尖灭线的误差与地层和不整合面的夹角有关,从而提出了地层油藏超剥尖灭线夹角定量外推这种新方法,通过实际资料的应用,较好地解决了地层油藏超剥尖灭线不准的问题,取得了良好地质效果.更多还原

【Abstract】 The stratigraphic reservoir is complex.The pitching-out line traced by using seismic reflection characteristic is quite different from the actual line when seismic description.The accurate implementation of stratigraphic pitching-out line is a key to explore stratigraphic reservoir successfully.In this paper it has been found that the error created by tracing stratigraphic overlapping-denudation pitching-out is relative to the included angle between formation and unconformity through testing forward model and making geostatistical,so the new quantive extrapolation method for calculating the angle included by stratigraphic overlap-denudation pitching-our is introduced,it is applied to solve the inaccurate stratigraphic overlap-denudation pitching-out and got the better effect.更多还原
