属性优化在台格庙太二段产能预测中的应用

摘要
地震属性从不同角度反映储层的物性特征,地震属性与储层岩性、流体性质、物性等参数之间存在着复杂的关系,不同工区不同储层参数所对应的最敏感的地震属性不同。所以有必要优选出对所求解问题最敏感、个数最少的地震属性组合,提高地震储层预测精度,改善地震属性有关的处理及解释方法的效果。主要阐述了属性优选的3种方法:①寻找样本井点间地震属性的最大差异;②拟合分析法进行属性优选;③利用平面图进行属性优选。钻探证实这几种优选方法在单井气产能预测中是可取的。
he seismic attributes contain information of reservoir characteristics.A very complex relationship exists between seismic attributes and lithology,fluid nature and reservoir petrography.The most sensitive attribute will change with the changes in surveys and studied reservoir types.Therefore,it's necessary to find what the most sensitive or effective attributes are to predict reservoirs.Which combination of attributes can help us to enhance the precision of seismic reservoir prediction and improve the utilization of the attributes? There are mainly three methods of the attribute optimization: ①seeking biggest difference of seismic attribute between the sample well sites;②applications of cross plot of attribute and reservoir parameters to optimization of attributes;③using the maps to choose attributes.It's been proved that these optimal methods are viable in gas output prediction.
