用测井资料预测探井碎屑岩储层岩性、物性及敏感性

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个央 ，物性参数。

Predicting Lithology, Petrophysical Property and Sensitivity of Clastic Reservoir in Exploration Wells with Logging Data

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.
