摘　　要：为了有效地识别和精确地评价以低孔低渗、微裂缝发育为特征的气层 ,用岩心资料刻度测井资料 ,在地质条件约束下 ,以细分层的“四性”关系研究为基础 ,提出了用直接识别、交会图、数学、综合分析等方法定性识别气层 ;在对裂缝深入研究的基础上 ,提出了气层的精细解释模型。该气层测井评价方案的投入应用 ,提高了测井对气层的识别能力和定量评价精度 。In order to effectively identify and accurately evaluate the gas-layer whose characters are low-porosity,low-permeability and grown micro-crack.On the base of four-characteristic relations’research,well-logging data are scaled by core data,then direct-identification,cross-plot,mathematics and comprehensive analyzing methods are put forward to idvntify gas-layers qualitatively in the restriction of geological conditions;On the base of cracks’s identification and the precision of gas-layers’s identification and the precision of gas-layers’evaluation in well-logging are improved,therefore science warrant is broughe forward to the thorough exploration and farther exploitation in Changqing oilfield.
