泥页岩储层各向异性正演模拟与属性分析

         

摘要

当前泥页岩油气藏的勘探取得了较大的进展,但仍处于探索阶段。以渤南洼陷沙三段泥页岩储层为例,在各向异性参数和裂缝参数分析的基础上,进行了各向异性弹性波场数值模拟,取得了较好的模拟效果。为了探索泥页岩裂缝型储层的预测方法,基于地震波场模拟数据,对甜心属性(振幅与频率的复合属性)、吸收属性等进行了提取和分析,认为利用这两类属性能够对泥页岩裂缝型储层进行有效预测,为今后该类储层的叠后地震属性预测指出了方向。%Shale oil and gas reservoirs have made great progress in exploration at present. But they are still at the exploratory stage. Taking shale reservoirs of Sha-3 member in Bonan sag for example, based on the analysis of anisotropy parameters and fracture pa-rameters, anisotropic elastic wave field numerical simulation was carried out to obtain better simulation results. In order to explore the prediction methods of fractured shale reservoir, based on seismic wave field simulation data, sweetheart attribute (the composite attributes of the amplitude and frequency), the absorption attribute and so on were extracted and analyzed to obtain the thought that using these two types of attributes can effectively forecast fractured shale reservoirs. It pointed out the direction for the post-stack seismic attributes prediction of such reservoirs.
