地震属性分析中水平切片的应用

利用地震数据体中含有的丰富地质信息,可以有效地进行储层预测。层拉平水平切片地层学解释方法是先将地震剖面目的层段做层拉平处理,然后对切片顺地层层面追踪,勾绘出各种地层现象,并以地层学的观点加以解释。该方法在吉林探区扶新南部地区的应用中,对于识别河道的展布趋势取得了较好的效果,而且发现了多期叠置的扇型沉积体。另外,还可指导反演数据体的解释,做到对岩性体从定性到定量的描述。

Application of leveling layer slice to the reservoir prediction

The abundant geological information contained in seismic data sets can be effectively used in reservoir prediction with stratigraphy interpreting method of level slicing, which firstly processes aimed layer segments into horizontal layers and then interpret the stratum geological phenomenon from the layer level slices in the view of stratigraphy. Application of this method in the south area of Fuxin, Jilin region, has greatly improved the identification of distributing trend of river channels and detection of the overlapping fan sediment bodies. In addition, the characters of lithology bodies can be described from quality to quantify by interpreting inversion data sets guided by this method.
