THE COMPACTION CORRECTION BASED ON THE PRINCIPLE KEEPING FORMATION GRAIN VOLUME AND MASS CONSTANT
-
摘要: 地层骨架体积质量不变压实校正方法发表后,引起同行专家的关注。为了让大家更好地了解这一方法,本文就相关的原理、概念、计算方法以及密度深度函数的曲线特征等,进行解释。我们认为压实校正过程中,古今孔隙度深度函数与古今密度深度函数不应该是分别等同的,更不能将地层骨架体积不变与地层骨架质量不变割裂开来。Δγ参数的引入,对地层骨架体积质量不变压实校正方法至关重要。Abstract: The paper titled "a new method for compaction correction", which was issued on Experimental Petroleum Geology (2000,Vol.22,No.2),has arosed some attention.In order to make the method more clear and more understandable,the related principle,concepts,calculating methods and characteristics of density-depth curves wers explicated.In processing of compaction correction,the paleo-porosity-depth function is not the same of the present porosity depth function,and the density-depth function shows same property.Parameter Δ γ is very important to the mew method for compaction correction,which is based on the principle keeping the formation grain volume and mass constant.
