摘要
应用测井资料确定储层岩性、物性是个基本问题，但确定敏感性是一个全新的课题。在收集薄片、铸体薄片、粒度、压汞、Ｘ－衍射、扫描电镜、物性、敏感性流动实验等各种岩心分析资料的基础上，首次探讨了如何应用测井资料确定储层敏感性的问题。从测井资料中提取了１４个岩性、物性参数。以这些参数为基础进行了储层敏感性与各参数的单相关分析，提出了单相关系数加权的方法来实现由测井资料预测储层敏感性。应用文中提出的方法对中国西部某油田进行了实际处理分析，结果表明由测井资料连续处理得到的速敏、水敏、盐敏、土酸敏和碱敏结论与该地区的敏感性流动实验结果基本吻合。
It is an essential practice to determine reservoir lithology and petrophysical
property by logging data, but to determine its sensitivity is a brand new subject. Based
on various core analyses, such as thin slices, cast slices, granularity analysis, mercury
injection, Xray diffraction, microscanning, porosity and permeability analysis, core fluid
sensitivity test, etc., how to determine the reservoir sensitivity with log data is
discussed for the first time. Fourteen petrophysical parameters are obtained from log
data. The sensitivity is correlated with all these parameters. According to respective
correlation analysis, a new single variable regression coefficient method is put forward,
which is used to predict reservoir sensitivity of a certain oilfield in western China. The
levelbylevel logging processing results show that the fluid velocity sensitivity, fresh
water sensitivity, salt water sensitivity, acid sensitivity and alkali sensitivity are
consistent with the core fluid sensitivity test results.
