辽河盆地大洼油田火山岩特征及其测井识别方法
|
摘要
为指导大洼油田火山岩油气藏勘探,利用K-Ar同位素测年、岩心薄片和测井等技术,研究火山岩层位、岩性、岩相及其空间展布特征。研究结果表明:辽河盆地大洼油田火山岩呈层状产出,这些火山岩年龄位于86.42～107.36Ma和45.72～51.25Ma这2个区间内,反映其形成时期分别为早白垩世晚期—晚白垩世早中期和始新世早期(房身泡期);主要的岩石类型有熔岩类、火山碎屑岩类及火山沉积岩类,始新世早期以熔岩类为主,白垩纪以火山碎屑岩类为主,它们分别产于溢流相、火山碎屑相、空落堆积相及火山沉积相中;通过对测井响应特征的综合分析及测井曲线组合的处理,建立不同类型火山岩的识别方程,为未取心井段地层、岩性对比提供了简便方法。
In order to guide the exploration of volcanic reservoirs in Dawa Oilfield, the horizon, lithology, lithofacies and their spatial distribution characteristics of volcanic rocks were studied by using K-Ar isotope dating, core slices and logging data. The results show that the volcanic rocks in the Liaohe Dawa oil field present in layer formation during deposition of Mesozoic and Cenozoic and the age of these volcanic rocks distributes in two ranges, one of which is from 86.42 Ma to 107.31 Ma, the other is from 45.72 Ma to 51.25 Ma, which reflects that the formation processions of these rocks are respectively from the latter lower Cretaceous to the early upper Cretaceous and the early Paleocene(Fangshengpao formation).The main kinds of the rocks are lava, volcanic detritus rocks and volcanic sedimentary rocks.In the early Paleocene, lava is dominating rock, and in the Cretaceous, volcanic detritus rocks are in the majority, and they respectively occur in the overflow facies, volcanic detritus facies, airfall stacking facies and volcanic sedimentary facies. Based on synthetic analysis of the logging response characteristics and the process of the combination of logging curves, recognizing equations for each kind of volcanic rocks are constructed, which provides a simple way for the comparisons of layers and the lithology correlation in the no core well intervals.
