贝西斜坡北部地区南屯组层序地层学研究
|
摘要
本文综合采用层序地层学、沉积学、地震地层学等的最新理论和方法,运用地震、测井、录井、岩芯等分析资料,对贝西斜坡南屯组层序地层格架、沉积相进行了深入细致的分析和研究。同时,结合凹陷的构造地质特征,对南屯组的生、储、盖组合规律进行了研究,并对有利砂体的分布范围进行了预测。成果为该区层序划分提供了可靠的依据,对今后该区油气勘探与开发具有重要的借鉴价值。
根据地震、综合录井、测井、岩芯等资料,依据井间可对比的原则,将贝西斜坡南屯组划分为两个三级层序,自下而上,南一段为一套完整的三级层序,南二段为一套完整的三级层序,T23反射层为两个三级层序的沉积转换面,并在体系域内追踪出两个地震反射层位。并描述了各层序及体系域的特征。
在层序划分、沉积环境及沉积相分析的基础上,确定研究区为多物源,南屯组沉积体系主要为扇三角洲-湖泊-湖底扇沉积体系。物源方向主要来自于西侧、西北侧、西南侧。同时,结合盆地的演化特征及岩性变化,做出了本区各体系域的沉积模式图。
综合考虑生、储、盖、圈闭等油藏形成的基本条件以及砂体的展布,预测出两个有利远景区带。
Based on the recent theory and method of Sequence Stratigraphy, Sedimentology and Seismic Stratigraphy, this paper uses seismic, logging and core information to analyze and research the sequence formation framework and sedimentary facie of Nantun member in Beixi slope belt deeply. Moreover, combined with structural geology feature of Beier depression, the combination law of oil source bed, reservoir, and cap rock of Nantun member is studied and the distribution area of favorable sand body is predicted. The result offers the dependable evidence for sequence division, and it is significant for the exploration and development of oil and gas.
According to seismic, comprehensive logging, logging and core information, this paper classifies Nantun member of Beixi slope into two three-order sequences according to the principle of correlation between wells. From bottom to top, K1n1 is a full set of three-order sequence, so is K1n2. T23 reflective layer is the sedimentary transformation surface between the two three-order sequences. This paper tracks out two seismic reflective layers in the system tract and describes the features of each sequence and system tract.
On the basis of sequence division, sedimentary environment and sedimentary facie, it is determined that research area has muti-sources. Nantun member sedimentary system is mainly fan delta-lake-sublacustrine fan sedimentary system. Source direction is mainly from west side, northwest side and southwest side. Meanwhile, sedimentary ideograph of each system tract in research area is completed combing with evolution n characteristics of the basin and lithology changes.
This paper predicts two favorable perspective plays by comprehensively considering basic conditions for the formation of reservoir (source bed, reservoir, cap rock and trap, etc) and distribution of sand bodies.
