去年,笔者等随勘探系部分师生参加了燕山辽西一带找油会战,重点对目的层段一震旦亚界高于庄组和雾迷山组的地层和岩相进行了详细调查,并在室内进行了400余块标本的薄片鉴定和一部分揭片、光片等项分析,从而研究了该地层的沉积特征、形成条件及其相模式,为研究油气的生、储、盖层及其组合特征和分布规律提供了岩石、岩相基础。这里谨将我们对该组段地层的沉积特征及相分析研究成果介绍如下:
Last year, with the participation of some teachers and students from the exploration department in the battle for oil exploration in the western Liaoning Province, we conducted a detailed investigation of the stratigraphy and lithofacies of the Upper Yuzhuang Formation and the Wumishan Formation in the target formation, Indoors, more than 400 specimens were identified in the laboratory and some of the samples were analyzed for the deposition, light and so on, so as to study the sedimentary characteristics, formation conditions and facies patterns of this formation. In order to study the hydrocarbon generation, accumulation, caprock and their combination The characteristics and distribution provide the basis of rock and lithofacies. Here we would like to tell you the sedimentary characteristics and phase analysis of this group of stratigraphic research results are as follows:
