摘　　要：江汉盆地潜江凹陷潜江组盐间非砂岩受化学沉积与机械沉积作用双重影响,岩性复杂,造成肉眼难以识别。通过对盐间非砂岩岩性的特殊性分析,提出盐间非砂岩储层特殊分析方法,明确认识到盐间非砂岩储层以泥质碳酸盐岩为主,碳酸盐质泥岩、混合岩次之;结合测井响应,可以从自然伽马、中子、密度测井曲线对储层岩性进行有效识别。Affected by both chemical and mechanical sedimentary action, the inter-salt non-sandstone reservoirs of Qianjiang Formation in Qian）iang Depression of Jianghan Basin have complicated lithology and therefore it is hard to identify them by naked eyes. This paper, having analyzed the particularities of the inter-salt non--sandstone reservoirs, proposes a special method for analyzing these reservoirs, clearly recognizes that the inter-salt non-sandstone reservoirs are mostly composed of muddy carbonate rock and carbonate mudstone, as well as mixed rocks secondarily. Combined with log response, it can be identified efficiently by gamma ray logging curve, neutron logging curve and density logging curve.
