【摘要】 如何合理提取裂缝型储层地震响应属性,描述储层的空间展布特征,是裂缝型储层预测研究的基础。通过提取塔北隆起西部A区块奥陶系一间房组(O2y)顶部碳酸盐岩裂缝型储层的地震响应特征,探讨了适合该区碳酸盐岩裂缝型储层预测的技术方法。在研究过程中,从裂缝成因理论出发,应用地震属性的几何学与波动学属性,从不同方面对裂缝型储层的预测进行了研究;首先通过本征值相干体、AFE(automatic fault extract)裂缝预测体的制作方法进行裂缝地震几何学属性方法研究,然后在测井岩石物理分析的基础上,应用地震联合反演方法对裂缝型储层进行地震反演方法研究,利用所提取的地震属性对研究区块的裂缝展布特征进行合理预测,解释了由于裂缝型储层各向异性而导致的用传统研究方法难以合理解释的勘探现象。描述了一种适合裂缝型储层预测的综合研究方法,对同类储层的预测有一定的参考意义。更多还原

【Abstract】 How to extract the seismic attribution to describe the spatial distribution of reservoirs was a basis for fractured reservoir evaluation.Through researching the seismic attribution extraction of carbonate reservoirs on the top of Yijianfang Formation(O2y)of Ordovician System in Block A of Western Region of Northern Tarim Uplift,the suitable techniques and methods related to prediction of fractured carbonate reservoirs were discussed.In the process of research,the geometry and kymatology of seismic attribution were used to study fractured reservoir prediction methods based on the theory of fracture origin.Firstly EGI and AFE attribution and simultaneous inversion method of fractured reservoir were researched.By extracting seismic attribution,the difficult exploration appearances,it provides reference for similar reservoir prediction.更多还原
