徐家围子断陷榆西三维深层地震资料综合解释
|
摘要
本论文以构造地质学、地震地层学、储层沉积学以及火山岩岩石学理论为指导,在认真分析和借鉴前人研究成果的基础上,充分利用地震、测井、钻井资料,采用多种地震手段,对徐家围子断陷榆西地区的地层格架进行了深入研究和分析,同时以营城组地层为目标,开展火山岩储层地震预测研究。
根据地震剖面和钻测井资料所反映的地层之间的接触关系及层序的沉积特征进行层序界面的识别和层序划分,建立了徐家围子断陷榆西地区的地层格架。
通过制作构造图和构造发育史剖面图对地层格架内重要界面的构造特征和构造演化进行研究。榆西地区主要受徐西、榆西和宋西断裂控制,这三大断裂对构造演化和地层沉积具有明显的控制作用,是深层气运输的重要通道,与火山岩和气藏的形成密切相关。本区的构造演化经历了断陷期、断坳转换期、坳陷期和构造反转期4个演化阶段。
通过对火山岩储层岩性、岩相及其与储集空间关系的研究,并结合徐家围子断陷的钻井资料,针对研究区营城组一段地层,从火山岩储层地震识别入手,应用全三维可视化与相干体技术预测出41个火山体,应用地震属性分析技术和地震反演技术对火山岩相带和火山岩储层进行预测。并以此为基础,通过剖面与平面结合分析得出:营城组一段火山岩在研究区内广泛分布;火山岩储层发育受火山机构、火山岩相带、断裂和埋深影响较大,以爆发相和喷溢相为主,靠近断层附近地区发育,物性好、厚度大。
最后,通过对徐家围子断陷深层天然气成藏条件的分析,再结合火山岩储层的预测结果以及多口井的试气结果,指出了研究区营城组一段的有利区带分布。
Guided by the theory of Structural Geology, Seismic stratigraphy, Reservoir Sedimentology and Volcanics Petrology, based on carefully analyzing and referring the research fruits of the predecessors, sufficiently using the data of seismic, well logging and well drilling, adopting several methods of seismic, the thesis has studied the stratigraphic framework of the strata in yuxi region of Xujiaweizi fault depression and this paper forecasts and researches the volcanic reservoir at the objective of Yingcheng formation of Xujiaweizi fault depression.
The strata is divided according to the contact relations of the strata which are reflected from seismic section, drilling data and log data. Accordingly the stratigraphic framework is set up in the yuxi region of Xujiaweizi fault depression.
The tectonic characteristics of the critical boundaries of stratigraphic framework and structure evolution are studied through the establishment of structure map and structural history profile. The strata in yuxi region were controlled by xuxi, yuxi ,songxi faults, These 3 breaks constructs the evolution and the stratum deposition .they have obvious control action, they are the important transportation channels, with volcanic rock and gas pool’s formation close related. The structure evolution process experienced 4 stages: faulting period, the period transformed from fault depression to sag, depression period and structure reverse period.
Through the research of the lithology, lithofacies and the relations with the accumulate room of volcanic reservoir, and combinded with the well drilling data of Xujiaweizi fault depression, In view of YingchengI formation, beginning with the seismic identify of the volcanic reservoir, using the technique of 3D visualization and coherence, 41 volcanic bodys in the target stratum are forecasted, using the technique of the seismic attribute analyzing and using the technique of the seismic inversion to forecast the volcanic lithofacies and the volcanic reservoir. Based on these, taking analysis of the section and the plane, it can be found that: the volcanic of YingchengI formation is destributed widely in the region of interest; The growing of the volcanic reservoir is affected largely by the volcanic edifice, the volcanic facies belt, the fault and the depth of burial, it is usually that the burst facies and the effusion facies are main, and the area near the fault is vegetal, the physical property is favorable and the thickness is high.
At last, through analyzing the diagenesis condition of the deep gas reservoir of Xujiaweizi fault depression, combinding with the forecast fruit of the volcanic reservoir and the test gas fruit of multiwell, the distribution of the beneficial areas are pointed out in YingchengI formation.
