对于非常规的储层,例如页岩气,它的储层区是脆性的。在描述不同岩石物理的参数中,杨氏模量E是衡量岩石的脆性的。计算杨氏模量E时,需要有效密度,而计算密度时需要的大偏移距地震资料通常是很难得到的。针对这种情况提出了一种新岩石物理参数E,即杨氏模量和密度的乘积,通过与属性的对比体现其在AVO叠前反演中的优势。
對于非常規的儲層,例如頁巖氣,它的儲層區是脆性的。在描述不同巖石物理的參數中,楊氏模量E是衡量巖石的脆性的。計算楊氏模量E時,需要有效密度,而計算密度時需要的大偏移距地震資料通常是很難得到的。針對這種情況提齣瞭一種新巖石物理參數E,即楊氏模量和密度的乘積,通過與屬性的對比體現其在AVO疊前反縯中的優勢。

The discrimination of fluid content and lithology in a reservoir is animportant characterization that has a bearing on reservoir development and itsmanagement. Amongst the different petrophysical parameters, Young's modulus (E) is a measure of their brittleness. But the densityis difficult to derive from seismic data, unless long offset information isavailable. Due to this, we propose a new attribute, E, which is the product of Young's modulus and density, having some advantages in the AVO pre stack inversion by comparison with Mu Rhoattributes.
