摘要
分析我国大中型气田形成条件,表明源岩供气能力、输导层输导天然气能力和盖层封气能力是我国大中型气田形成的3个主控因素.在此基础上,利用加权平均法建立气藏形成主控因素综合定量评价方法,并对我国31个大中型气田形成主控因素进行综合定量评价,表明形成主控因素综合定量评价以好等级为主,其次为中等.我国31个大中型气田形成主控因素综合定量评价与其天然气储量丰度为正比关系,即随着气藏形成主控因素综合定量评价增加,其天然气储量丰度增大.要形成高储量丰度及中等储量丰度的大中型气田,气藏形成主控因素的综合评价应为好等级及中等级.
By the analysis of formation conditions of large and medium gas fields in China,supplying gas ability of source rock,transporting gas ability of transporting pathway and sealing gas ability of cap rock were considered to be 3main factors controlling formation of large and medium gas fields.By use of weighted average method,a set of comprehensive and quantitative evaluation method for main control- ling factors of gas reservoirs was established.By comprehensive and quantitative evaluation for main controllin...
