地震波形状描述技术及其在地震相分析中的应用
|
摘要
地震波的波形变化及其分布规律,是重要的地震参数之一。对地震波形中包含的地质信息加以分析和应用,将有利于提高储层预测,油藏描述精度和钻探成功率。以波形的形状进行分类,并进行地震相和沉积相分析,是目前应用较为广泛的一类地震属性分析的方法技术。在这类技术中,其核心是波形的形状描述和刻画技术。这里以Stratimagic软件为例,通过对构成地震波形状的主要参数(振幅、相位、频率)对其波形状变化影响的细致分析和比较,总结出了可以利用地震波的形状变化规律及形状描述方法,探讨了依据该波形形状分类在地震相分析中的效果和意义。
In seismic attributes,the general variation of waveform and its distributed rule is most important seismic parameter.Picking and identifying the waveform information is of benefits to reservoir prediction,reservoir description and improving drilling successful rate.Using waveform to create seismic facies is to use neural network technique to quantitatively describe the general variation of seismic signal.The core of this technologies is the wave shape description and characterization techniques.Taking Stratimagic for example,by the detailed analysis and comparison with the influence over waveform shape changes caused by the main parameters(amplitude,phase,and frequency) which make up of the waveform shape,this paper summarizes waveform shape variation and waveform shape description method which can be used and discusses the effect and significance wave shape classification in Seismic facies analysis.
