This paper used rock-capillary model to simulate the formation pore volume,and derives the variation equation between paraffin precipitation and formation parameters using the correlation among surface area to volume ratio,porosity and permeability,etc.
根据岩石—毛细管模型,以及地层孔隙度、渗透率和比面的关系推导出了石蜡沉积以后的孔隙度和渗透率的变化公式,并通过实例计算证实石蜡沉积以后,地层的孔隙度和渗透率都有不同程度的下降。
