哈萨克斯坦南图尔盖盆地层序地层模式
|
摘要
哈萨克斯坦南图尔盖盆地的隐蔽油气藏日益成为勘探重点,如何借助层序地层学原理去寻找储集物性好的隐蔽圈闭成为油气勘探的难点。根据经典层序地层学原理,应用测井资料小波分析技术,结合岩性、测井曲线和地震反射等层序界面识别标志,对南图尔盖盆地上侏罗统和下白垩统进行了层序划分,共划分为4个三级层序、10个体系域。根据构造演化阶段的不同,划分出断拗转换期和拗陷期2种层序地层模式,前者主要发育滨浅湖和三角洲沉积,后者发育河流相沉积。其中断拗转换期层序地层模式中主要发育三角洲地层尖灭油气藏和滩坝透镜体油气藏,拗陷期层序地层模式中发育下切河道油气藏和河道透镜体油气藏。
With the development ofexploration,subtle reservoir is becoming the most important part in South Turgay Basin.It is difficult to find subtle reservoir in the framework of sequence stratigraphy.With the application of the principles of sequence stratigraphy,Upper Jurassic and Lower Crataceous are divided into four 3rd order sequences,ten system tracts by the identification marks of sequence boundary including lithologic characteristic,wavelet analysis,seismic section and so on.The sequence of falult-depression transform period is divided into three parts,and major grows delta,fan delta and beach-bars.The sequence of depression period is divided into two parts,and the major is in form of braided river and meandering river.According to the structural evolution,there are two types sequence stratigraphy model.The first major one mainly develops pinchout reservoir of delta,and lenticular sandstone reservoir of beach-bars.And the later develops downcutting channel reservoir and channel lithologic reservoir.
