摘要
本文以层序地层学和沉积学理论为基础,通过岩芯观察描述、测井、地震资料综合分析,系统研究了东营凹陷牛庄洼陷沙三上亚段~沙二段层序地层划分与演化、沉积相标志特征、沉积相类型及其时空展布规律。
     在层序地层学基本理论的指导下,对研究区探井岩性、测井曲线、地震剖面及其它相关资料进行详细研究,结合小波分析等研究方法,识别出了沙三上亚段~沙二段的层序界面,划分为两个层序,其中沙三上亚段~沙二下亚段为层序S1,沙二上亚段为层序S2。沙三上亚段~沙二段地层内部可以进一步划分为6个准层序组、21个准层序。层序S1是一个二分层序,包含湖进和湖退两个体系域,分为3个准层序组及9个准层序。准层序组自下而上依次命名为S1-1、S1-2和S1-3,准层序包括第13到第21准层序,其中S1-1包含20、21两个准层序,S1-2包含16-19四个准层序,S1-3包含13-15三个准层序。层序S2是一个三分层序,包含低位、湖侵和高位三个体系域。进一步可以划分为3个准层序组和12个准层序。准层序组自下而上依次命名为S2-1、S2-2和S2-3,准层序为第1到第12准层序,其中S2-1包含10-12三个准层序,S2-2包含7-9三个准层序,S2-3包含1-6共六个准层序。S2-1准层序组对应于层序S2的低位体系域,S2-2和S2-3准层序组对应于湖侵体系域。通过单井层序划分、连井剖面追踪对比,建立了牛庄洼陷沙三上亚段~沙二段层序地层格架。
     通过对岩芯、测井、录井资料等的沉积相标志研究,在牛庄洼陷沙三上亚段~沙二段地层中识别出三角洲、曲流河、滩坝及湖泊等沉积相类型。其中曲流河河道,三角洲前缘水下分流河道、分流河口砂坝、远砂坝以及滩坝是主要的砂体成因类型。三角洲的物源主要来自洼陷的东部和南坡。砂体的分布平面上受古水深及水动力条件的控制,纵向上演化受湖盆水体变化的影响。
     为了能更加真实深入的了解低可容空间下的三角洲沉积特征,本文对东营沉淀池三角洲的现代沉积特点进行了考察和详细解剖,取得了一定的认识,并与牛庄洼陷沙三上亚段~沙二段地层中的三角洲进行了比对,总结出了低可容空间下的三角洲沉积模式,为牛庄洼陷沙二段的油气勘探提供了有效的指导,也为相似沉积环境下三角洲沉积体系的研究提供了帮助。
Through the relevant data such as the core description , well-log and seismic analysis , this paper has studied the sequence division and evolution , the facies marks feature, the facies type and its distribution rules of the upper segment of Es3~Es2 in Niuzhuang sag on the basis of the sequence stratigraphy and sedimentology.
     Under the guide of the sequence stratigraphy theory, the sequence boundaries about the upper segment of Es3~Es2 have been recognized and further divide it 2 sequences: the upper segment of Es3-lower segment of Es2 is S1 sequence , the upper segment of Es2 is S2 sequence .The upper segment of Es3~Es2 is divided into 21 parasequence , which include 6 parasequence formation on the studies of the core description , well-log and seismic and the other relevant data , combining with wavelet analysis.
     The S1 sequence is a dichotomize sequence,include the TST and the RST, further divided 3 parasequence formations and 9 parasequence. The sequence formations are entitled S1-1 , S1-2 and S1-3 from the bottom to the top, included the 13-21 parasequence: the parasequence 20-21 pertain S1-1, the parasequence 16-19 pertain S1-2, the parasequence 13-15 pertain S1-3. The S2 sequence is a tripartition dichotomize sequence ,include the LST ,TST and HST, further divided 3 parasequence formations and 12 parasequence. The sequence formations are entitled S2-1 , S2-2 and S2-3 from the bottom to the top, included the 1-12 parasequence: the parasequence 10-12 pertain S2-1, the parasequence 7-9 pertain S2-2 , the parasequence 1-6 pertain S2-3. The S2-1 parasequence formation corresponds to the LST of S2, S2-2 and S2-3 correspond to TST. The sequence framework of the upper segment of Es3~Es2 in Niuzhuang sag has been established on the basis of individual well sequence division and well tie section.
     There are delta , meandering river , beach bar and lacus facies in upper segment Es3~Es2 of Niuzhuang sag by the relevant data such as the core description , well-log and log data. The channel of meandering river, the distributary channel of delta front ,distributary mouth bar , distal bar and the beach bar are the main sand body types. The provenance of delta is the eastern and south slope of the sag. The sand body distribute is controlled by the palaeobathymetry and hydrodynamic force in plane, and influenced by the change of water of lacus basin in the longitude.
     In order to comprehend the feature of delta in lower contained vacuity ,this paper investigate the delta sediment feature of Deposit pool delta in DongYing , then draw certain knowledge , on this basis comparing with the delta of the upper segment of Es3~Es2 in Niuzhuang sag , in the end generalize the model about delta which deposits in lower contained vacuity. The fruit of this paper provides direction for the exploration activity in Es2 of Niuzhuang sag , also is benefit to the study of the delta depositional system in the same deposition condition
