利用叠前密度反演预测岩性的应用研究
|
摘要
珠江口盆地番禺某地区使用常规的叠后波阻抗较难识别储层岩性。使用叠前密度反演方法,即利用不同炮检距道集数据以及纵波、横波、密度等测井资料进行反演,同时反演出纵波阻抗、横波阻抗、密度等。利用该技术对该地区进行储层预测,结果表明密度可以有效的区分该区的储层,并能清楚反映出尖灭等地质现象;目的层SB21.0沿层属性展示出有利储层的分布区域,预测区得到了钻井证实,证明该技术是有效的。
It is difficult to identify reservoir lithology using routine post-stack impedance in Panyu region of Zhujiangkou Basin,so prestack density inversion method using different processed inspection such as offset gathers,p-wave,s-wave,and density logging data was applied in this area,and shear impedance,impedance,density and so on were obtained at the same time.The result of reservoir prediction in this area using the technology showed that the density could effectively distinguish the reservoir,and could clearly reflect geological phenomenon of wedge.The layer properties of SB21.0 showed regional distribution of favorable reservoirs which was confirmed by drilling proves that the technology was effective.
