新岩石物理参数研究

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。

Study on the New Petrophysical Parameters

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 Youug＇s modulus and density, having some advantages in the AVO pre stack inversion by comparison with Mu Rhoattributes.
