摘　　要：目的通过研究,建立合理的孔隙度解释模型。方法分别应用岩心刻度测井法中的一元回归法,数理统计相关型法中的二元回归法建立孔隙度解释模型。结果一元回归法所建立的孔隙度解释模型相关性仅为0.154 6,利用二元回归法建立的孔隙度解释模型相关性可达O.919 9,其检验的显著性强。结论二元回归模型适合本区孔隙度的解释,此种方法也适用于绝大多数砂岩油藏。Aim To establish a rational porosity interpretation model. Methods The methord of porosity logging interpretation is a commonly used way for porosityinterpretation. Use unary line regression and binary line regression method to build porosity model. Results After comparison and validation, it indicates that for sandstone reservoir in Zichang area, the porosity interpretation model established by unary line regression method,the correlation is low, the binary line regression method is better. It has stronger test significance. Conclusion Binary line regression is much suitable for this area. This method also applies to the vast majority of sandstone reservoirs.
