摘要

文安斜坡位于渤海湾盆地冀中坳陷霸县凹陷东部斜坡的中段,从该区域已有油气成藏研究来看,构造油气藏、岩性油气藏、岩性-构造油气藏和断块油气藏等各种类型的隐蔽油藏在该区均有发育。地震反演对储层砂体在空间横向上的分布有很好的预测作用,可作为发现隐蔽油气藏的有效手段,井约束下的波阻抗反演在岩石物性差异较大的地区具有较好的应用效果。对该地区通过约束稀疏脉冲反演(CSSI)研究进行储层预测,对该工区内隐蔽油气藏的发现有重要的指导意义。
Wen'an slope is located in the middle of the eastern slopes of Ba County depression in Bohai Bay Basin.From the study of the hydrocarbon accumulation in this region,structural reservoir,lithologic reservoir,lithologic-structural reservoir and fault block reservoir such as various types of subtle reservoir develop in the area.Seismic inversion for reservoirs sandstone in the distribution of the horizontal space has a very good prediction.It can be found disguised as an effective means of subtle reservoir.Well-constrained impedance inversion in the different rock properties of the region has a better effect.In this paper,bound in the region through the constrained sparse pulse inversion(CSSI) study reservoir prediction,the discovery of subtle reservoir have important guiding significance in the work area.
