碳氧比测井在中低孔隙度下的应用

李玉玲张宇晓：碳氧比测井在中低孔隙度下的应用，测井技术，１９９６（６）２０，４５４～４６０。虽然碳氧比能谱测井解释方法在中低孔隙度下的应用受到一定程度的限制，但通过泥质含量、灰质含量、矿化度对碳氧比测井的影响分析和校正，可使其解释结果得到一定程度的改进，从而可提高碳氧比测井在中低孔隙度下用于区分油层、水层及油层水淹级别的应用效果。

Though application of C/O log to mediun low porosity zones, to a certain extent, has been limited, its interpreted results can be improved by correcting the effect of shale volume, calcium content and salinity on C/O log, and hence, promoting the application efficiency of C/O log in determining oil and water beds as well as waterflooding extent.
