Evaluation Method for Unconventional Log Data of CBM Reservoir
摘要
Abstract
Energy spectrum, electrical imaging and dipole array acoustic logging information in A area, Qinshui basin, are used to comprehensively evaluate regional CBM(coalbed methane). From analyses of maceral, metamorphic grade, caprock conde and structure development, an e-valuation method using unconventional logging data to dividing the gas content system of coalbed were established. When the metamorphic grade, maceral and ash content of coalbed was the same or the similar, the gas content system of coalbed could be divided into 2 levels by combining dipole array acoustic logging data with electrical imaging data By contrasting with the actual information, the evaluation method was confirmed to be correct and reliable in dividing the gas content system of coalbed, which offered accurate logging data for the overall evaluation of region CBM (coalbed methane), and provided reliable technical support for the next CBM exploration and development.关键词
