应用地震属性确定莫西庄地区沉积微相的事例
|
摘要
地震属性在碳氢检测、储层预测和层序地层解释中有广泛的应用。本文在宽方位三维地震资料精细解释的基础上,根据地震振幅属性分析、地震相干分析及谱分解下的能量谱和相位谱的提取,结合区域沉积相和单井相,研究了准噶尔盆地莫西庄地区侏罗系三工河组二段砂岩的平面沉积微相,明确了沉积微相的主要特征。研究结果表明,该方法可以较好地预测出地层沉积特征和砂体展布规律。
There is wide application for seismic attributes in hydrocarbon detection, reservoir prediction and sequence-stratigraphic interpretation. On the basis of fine interpretation of 3-D wide-azimuth seismic data, based on analysis of seismic amplitude attribute, seismic coherent analysis and detection of energy spectrum and phase spectrum under the spectrum decomposition and in combination with sedimentary facies and single-well facies in the region, the paper studied Jurassic Sangonghe Stage Second Segment sandstone in Moxizhuang area of Junggar basin and clarified major feature of sedimentary micro-facies, which showed that the method is able to better predict sedimentary feature of strata and distributing rule of sand body.
