摘　　要：随着资源探明率增加,江汉盆地常规砂岩油藏的勘探难度不断加大。近年来,通过加强基础地质研究,转变勘探思路,实现了碳酸盐岩油藏的勘探突破和页岩油领域的有效推进。从勘探实践出发,结合研究区钻井、测井、录井及岩心分析化验等各类资料,开展地质综合研究与有利区评价,揭示了江汉盆地岩性和岩相的空间展布特征、沉积模式、储集空间类型、油气富集条件及成藏模式,明确了颗粒碳酸盐岩和颗粒混积岩具有良好的储油能力,是常规勘探开发的新类型油藏和增储增产的现实阵地,其总资源量为3.7×10^(8)t。纹层状泥质白云岩+白云质泥岩岩相组合具有良好的生-储配置,主要分布在新沟嘴组下段Ⅱ油组,是非常规页岩油勘探的最有利相带,有望实现页岩油新领域的勘探突破,预测资源量为3.62×10^(8)t。With the increase of resource exploration rate in Jianghan Basin,the difficulty in exploring conventional sandstone reservoirs is continuously enlarged.In recent years,by strengthening basic research and changing exploration ideas,the exploration breakthrough of carbonate reservoir and the effective promotion of shale oil field have been achieved.According to the exploration practice,in combination with the analysis and experiment data of drilling,testing,logging and cores,comprehensive geological research and favorable area evaluation were carried out in the study area.The research reveals the spatial distribution characteristics of lithological and lithofacies,sedimentary patterns,reservoir space types,oil-gas enrichment conditions,as well as accumulation mode.Moreover,it has been clarified that granular carbonate and mixed granular rock have good oil storage capacity,which are new types of oil reservoir for conventional exploration and development,and also the actual field for increasing reservoir and production,with a total resource of 3.7×10^(8)t.The facies assemblage of shale mixed with micrite(dolomite)has good oil generation ability,mainly distributed in the second oil group of lower Member of Xingouzui Formation.It is expected to achieve a breakthrough in the exploration of new field of shale oil,and the resource amount is predicted to be 3.62×10^(8)t.
