乌尔逊凹陷乌北地区铜钵庙层序特征研究
|
摘要
本文综合利用层序地层学、沉积学、构造地质学、石油地质学等最新理论和方法,运用地震、测井、录井、岩心等资料,对乌北地区铜钵庙组地层的层序地层格架、沉积相进行了深入细致的分析和研究。同时,结合前人研究成果,利用上述研究成果对有利区带进行预测。本次研究为该地区的层序划分提供了可靠依据,对今后该区油气勘探与开发及井位部署具有实际的指导意义。
在乌北地区铜钵庙组顶底界面分别为T3和T4,且均为凹陷内较大不整合面。在认真分析和借鉴前人研究成果的基础上,通过井震结合,实现了钻井分层与地震界面的统一,建立了层序地层格架。将铜钵庙组划分为1个三级层序、4个四级层序,并在四级层序内对准层序、准层序组、体系域和沉积体系进行了研究。
通过对研究构造沉降、气候变化、沉积物供给和湖平面变化等层序控制因素的分析,阐明了各种控制因素对层序发育的影响作用。研究认为,构造沉降是控制断陷期地层层序发育的主要因素。
综合露头、地震、钻测井等资料,明确了铜钵庙组沉积相特征、沉积模式和沉积体系展布特征。铜钵庙组发育的沉积相类型有:扇三角洲相、湖泊相及火山岩相。
最后,综合生、储、盖、圈闭等因素,指出研究区内的有利勘探区带。
Based on the latest theories and methods of the sequence stratigraphy, sedimentology, structural geology, petroleum geology, as well as the analytical data of seismic, well logging, core, the author analyses and studies the sequence stratigraphic framework and precipitation facies of the TongBoMiao formation in the northern area carefully and deeply. At the same time, combining with the research results of previous studies and the initial work above, the autho carries on the forecast about the advantageous area. The results enrich the theories of the sequence stratigraphy and the sedimentology, and they also have actual guiding significances on the future hydrocarbon exploration and development as well as the allocation of the well location in the area.
In northern area, T3 and T4 which are the top and bottom interface of TongBoMiao group are a larger regional unconformity in the block sag. On the basis of analysing and drawing on the experience of the results of previous studies carefully,combining the well logging with seismic, we success on the unification of the drilling stratification and the seismic interface, and establish the sequence stratigraphic framework. we divide the TongBoMiao formation into one three-order sequence, four fouth-order sequences and we also study parasequence,parasequence set , systems tract and sedimentary system.
Through ananlysing the controlling factors on the sequence such as structure subsidence, climatic change, sediment supply and lake level change in the research area, we interpret the effects of various controlling factors on the sequence development. The finding suggests that structure subsidence is the main factor on controlling the layer sequence development of the faulted period.
Combining with the data of crop, seismic, well drilling and logging, the characters of precipitation facies, depositional model and depositional systems distribution of the TongBoMiao formation are defined. The main precipitation facies in the TongBoMiao formation are braided fluvial delta facies , lacustrine facies, and volcanic facies.
Finally, considering of the factor of oil generation, storage, cap rock, trap comprehensively, we point out the favorable exploration regions in the research area.
