【摘要】 以层序地层学、构造地质学、沉积学及盆地分析等学科新理论为指导,综合应用地震、钻测井、岩芯和野外露头资料,建立了松北宾县-绥化地区中生界层序地层框架,并详细研究了超层序、层序及体系域等关键界面的特征。对不同类型的层序界面加以分析概括,发现该区存在八种类型的层序界面,每种层序界面形成的沉积环境不尽相同。在此基础上,结合研究区不同构造演化时期的古地貌特征,以详实的地震相分析和单井沉积相标志分析为手段,钻井、地震紧密结合,阐明了研究区中生界沉积相类型及体系域格架下的沉积相平面展布特征,分析了沉积相在不同构造演化时期的时空演化规律及其相应的地球动力学背景;得出了研究区断陷期构造活动控制沉积、坳陷期物源控制沉积的结论。利用地震反演及关键层位的属性提取分析成果,在层序、古地貌、沉积相研究的基础上,探讨了各体系域砂体发育分布规律,建立起对储集体和烃源岩分布具有重要预测功能的层序地层学模式;同时通过对松辽盆地油气成藏条件类比分析,预测了研究区的有利储集相带。坳陷期,海伦油气勘查区的西部、绥化油气勘查区的东北部和铁力油气勘查区的中部是稠油和油砂的有利勘探区带;断坳转换期,海伦油气勘查区的西部、绥化油气勘查区的西南部、哈尔滨东部油气勘查区的西北部和宾县断陷是天然气的较有利勘探区带,断陷期,绥化油气勘查区的中部、铁力油气勘查区的中部和宾县断陷是天然气的较有利勘探区带。
【Abstract】 With the guidance of the new theory of sequence stratigraphy, tectonic geology, sedimentology and basin analysis and using the data of seismic, drilling-well logging, drilling core and field exposure, founded the Mesozoic sequence strata framework in Binxian-Suihua area of the Songliao Basin. Then studied the characteristic of the key sequence boundary about super-sequence, sequence and system tract. There were 8 styles sequence boundary through the analysis of the different style sequence boundary. The forming sedimentary environment of each sequence boundary was different. Based on seismic facies analysis and single-well facies markers and combined with the palaeogeomorphology character in different periods of structural evolution, described the Mesozoic sedimentary styles and the plane distribution character under the system tract framework. It was concluded that structual movement controlled the sedimentary in the fault subsidence period and sedimental resource controlled the sedimentary in the downwarp period through analyzing the sedimentary facies evolution character in different structural evolution periods and their geodynamics background. Using the result of the seismic inversion and the key positions’property, discussed the development and distribution of the sandstone in different system tract. On the basis of analyzing the sequence, parageomorphology and sedimentary facies, built the sequence stratigraphy models of predicting the reservoir and hydrocarbon rock distribution. Through the forming conditions of oil and gas reservoir analogy analysis in Songliao Basin, predicted the profitable reservoir. During the downwarp period the profitable exploration area of heavy crude and oil sand lied in the west of Hailun gas and oil prospect, the ease-north of Suihua gas and oil prospect and the middle of Tieli gas and oil prospect. During the transform period of the fault subsidence and the downwarp the profitable exploration area of gas lied in the west of Hailun gas and oil prospect, the west-south of Suihua gas and oil prospect, the west-north of Haerbin gas and oil prospect and Binxian fault depression. During the fault subsidence the profitable exploration area of gas lied in Binxian fault subsidence, the middle of Suihua and Tieli gas and oil prospect.
