摘要
应用岩心、录井、测井、重矿物、粒度分析等资料,采用现代精细沉积学方法,对松辽盆地南部花敖泡海坨子地区泉四段沉积微相类型进行研究.结果表明:花敖泡海坨子地区泉四段下部为三角洲平原沉积,主要发育分支河道、河道间、决口扇等微相;上部为三角洲前缘沉积,主要发育水下分支河道、河口坝等微相.在对研究区的沉积微相平面展布特征及变化规律分析基础上,认为泉四段分支河道、少部分决口扇及水下分支河道砂体厚度和规模较大,具有较好的储集性能,是形成油气藏的良好储层.
By the application of core,logging,heavy minerals,grain size analysis,the introduction of modern fine sedimentation method,we dealt wity the sedimentary microfacies types of Aobaota-Haituozi area in the Southern of Songliao Basin.The results show that: the main sedimentary microfacies types of the lower of the forth member of Quantou are delta plain deposits and its main sedimentary microfacies are branch channels,interchannel,crevasse splay microfacies.And the upper parts are delta front deposition and its main types are distributary channel,estuary dam,etc.Under the study of the distribution pattern and evolution,we think the sand of branch channel,crevasse splay,small underwater distributary channel are thick and large,being favorable reservoir for oil-gas formation with good storage performance.
