摘要
本文从密度和中子测井信息中提取的地层体积密度及含氢指数,分别同气层体积密度及含氢指数的下限值作比较,前者小于后者,直观指示为气层。应用气层下限值指示气层,提高了测井找气的直观性、准确性。
In this paper, the stratigraohic volume density and hydrogen index gained from the information of density-neutron logging are respectively compared with both the low-limit values of gas formation. If the former are less than the latter, the strata can be determined as gas formation through being directly viewed. The properties of direct view and accuracy of surveying gas are raised. 34~40
