摘要

A new procedure is proposed and a corresponding method of analysis developed to locate water-conducting fractures and obtain fracture inflow rates by means of a time sequence of electric conductivity logs of the borehole fluid. The physical basis of the analysis method is discussed. The procedure is applied to a synthetic set of data, which shows initiation and growth of four conductivity peaks in a 900-m section of a 1690-m borehole, corresponding top water-conducting fractures intersecting the borehole. We are able to match all four peaks and determine the flow rates as well as the salinity of the water from these fractures. 10 refs., 13 figs., 2 tabs.
