Identification and evaluation of caprock by log information
Yang Tao-ta · Petroleum Geophysics · 2014
The log information have high vertical resolution, good continuity and easy to obtain, the caprock shows obvious characteristics of response on the log information, after the calibration of the log information is analyzed,the continued caprock evaluation data in vertical could be obtained to compensate the lack of the data dispersion, it is economic and prompt. According to the relation between the caprock and the log responses, the parameters are obtained by the log information to quantitatively evaluate the quality of the caprock. The development characteristics and log identification evaluation methods of the caprocks of the salt rock, coal, volcanic rock, dense sandstone, and carbonate rock etc were summarized.
