Method for detecting hydrocarbon zones in a geological formation |
摘要 |
A method for detecting hydrocarbon zones in a geological formation, including obtaining a plurality of pulverized drill cutting samples representative of the geological material encountered at measured depth intervals, each drill cutting obtained at periodic intervals during the drilling process; measuring each cutting sample with a color measuring device to obtain a value representing the degree of lightness of the particular cutting sample; and analyzing the measured lightness values by order of borehole depth that the respective cutting sample was obtained to determine the presence of geological zones likely to possess producible hydrocarbons. L* data may be combined with other well logging data to improve the hydrocarbon layer determination accuracy. A method also for locating the drill bit within a desired hydrocarbon layer during directional drilling. |
