塔南—南贝尔凹陷沉南屯组沉积相特征
|
摘要
在大庆油田外围勘探区块中,塔南—南贝尔凹陷是一个潜在有利勘探区块。石油地质背景复杂,前期资料少,为查明研究区的油气分布,需对研究区的沉积环境、沉积相及其特征进行研究,建立准确的沉积模型。根据岩芯观察,粒度分析、测井相,分析研究区水动力学特征、构建沉积相模式,预测砂体分布范围;利用地震属性分析,预测井间砂体展布范围。综合上述研究成果,对全区南一段和南二段地层单元的沉积相进行预测。研究结果表明:塔南—南贝尔凹陷主要发育冲积扇、扇三角洲、近岸水下扇、湖底扇和湖泊沉积体系,其中扇三角洲和湖泊沉积体系是研究区内最为发育的沉积体系类型。
Tarnan—Southbell depression is a potentially lucrative exploration outer block of Daqing Oil Field.As oil geological background is complex with less information,in order to identify the research area of the oil and gas distribution,it is necessary to study area depositional environment,sedimentary study phase and its characteristics,and to establish an accurate model of the deposition.According to the core observation,particle size analysis and log-phase,the hydrodynamic characteristics of the study area was analyzed,sedimentary facies model was built,and the sand-body distribution was predicted.By using the seismic attribute analysis,the inter-well sand-body distribution was forcasted. Based on the above mentioned recognition,the sedimentary facies was predicted in the 1st and 2nd member starta units of Nantun Formation.The results show that the Tarnan—Southbell depression mainly develops alluvial fan,fan delta, nearshore submarine fan,lake floor fan and lacustrine depositional system in which fan-delta system and lacustrine depositional system is the most developed type.
