【摘要】 番禺4洼陷是一个主要受构造作用控制形成的陆相断陷箕状洼陷,在建立番禺4洼陷等时层序地层格架的基础上,通过最佳波形分类数的选取,利用自组织神经网络技术,进行了层序格架内的地震波进行波形分析和有效分类,研究了层序格架内地震波波形特征的平面展布规律,进而分析沉积相和有利储集层分布特征。更多还原

【Abstract】 Seismic waveform was the integral reflection of various geologic information including sedimentary facies and lithologic facies.Panyu 4 Depression was a duspan-like depression of continental fault depression which was formed by structural control.On the basis of establishing isochron sequence stratigraphic framework of Panyu 4 Depression,by choosing the numbers of optimal waveform classification,the seismic waveform in the sequence framework is analyzed and identified effectively,the areal distribution rules of the waveform characteristics in the framework was studied,therefore sedimentary facies and favorable reservoir distributive characters are analyzed by the method stated above.更多还原
