岩石电阻率毛管理论的验证

The Research of Useing Capillary Theory to Achieve Resistivity of Water-bearing Rocks

本文简要介绍了新的毛管理论.它是孔隙结构理论的一种,认为多种介质是由无限多的毛管组成。毛管压力曲线呈双曲线,毛管的孔径的分布曲线是幂函数。本文还着重用毛管理论公式求取含水岩石电阻率,在中原油田桥口、白庙地区作了一些验证,效果良好。

This paper summarized the ncw capillary theory which is one of the theories of pore geometer.The paper considcrcd that porous mcdium consists of a lot of capillary tube,the distribution curve of capillary pressure is hyperhola and the distribution curve of the di- ameter of capillary tube is power function.The capillary theory advanced recently by combining the Helmholtz equation with flow potential is used in this paper to achieve resistivities of water-bearing rocks.Some tests have been done by us in Zhongyuan Oil Field and the results are satisfactory.
