摘要
以吐哈盆地十三间房地区侏罗系地层为研究对象,通过分析研究区内多个井口的地化资料、岩心样品等地质资料,对研究区可形成油气藏层位进行研究,总结其有利成藏条件,预测勘探有利区域。结果表明,十三间房地区烃源岩质量较好,整体处于成熟阶段,生烃潜力高;十三间房地区有利成藏条件为良好的烃源岩发育质量和良好的沉积-储层发育,生烃时间与构造圈闭匹配性好,圈闭资源量大;根据烃源岩生烃强度、Ro排烃门限及储层发育情况,预测十三间房中北部及山前洼陷带可作为今后勘探的有利目标区。
Taking the Jurassic stratum of Shisanjianfang Area in Turpan-Hami Basin as the research object,through analysis of many local wellhead and core samples,probing potential reservoir layer of oil and gas in the area,its favorable reservoir forming conditions were identified and potential reservoir was predicted.The results showed that the target area had efficient source rocks with high hydrocarbon generation potential.The favorable reservoir-forming conditions in the area included high source rock quality and good sedimentation.The hydrocarbon generation duration was well matched with the structural trap with bountiful trap resources.According to the hydrocarbon generation intensity of source rock,the Ro hydrocarbon expulsion threshold and the reservoir development,it can be predicted that the central and northern part of the target area and the sag zone in front of the mountain can be used as favorable target areas for future exploration.
