【摘要】 着重叙述地震沉积微相研究的基本方法，包括①自然电位测井曲线的富氏谱分析，提供了进一步研究自然电位曲线的另一种手段；②由瞬时速度的基本概念出发，利用Ｖ进行了较稳定砂层的横向预测研究；③薄互层的层速度是微相研究的基础，提出了计算薄层层速度的方法（ＷＭＯＣＢ公式），详细研究了其误差，得出关于误差分布的一系列有益的结论；④利用模式识别技术建立了地震沉积微相判别系统，对实际资料的试算表明该系统是可靠的。更多还原

【Abstract】 The paper mainly discusses several basic methods about research ofseismic sedimentary microfacies.①Fourier spectrum analysis of SP well logs providesanother method for further study of SP logs.②The transverse prediction os stable sandlayer is completed by the application of instantaneous velocity.③Since the intervalvelocity of thin interbedding is fundamental to the microfaciea research a computationfrmula of the interval velocity of thin interbedding is put forward. The error has beenstudied in detail with a seriea of conclusions about error distributon.④The system ofseismic sedimentary microfacies is set up through pattern recognition. Field dataprocessing indicates the reliability of the system.更多还原
