克拉玛依油田八区下乌尔禾组沉积相特征及演化规律

Sedimentary Characteristics and Evolution in the Under Wuerhe Formation of the 8th Area of Karamay Oilfield

为了更好地探明克拉玛依油田八区下乌尔禾组油气潜力,提供老井挖潜的有利区带,笔者应用现代沉积学理论,充分利用岩心、钻井、测井等资料,深入细致地研究了八区下乌尔禾组的沉积特征,从中识别出共识别出2种亚相、9种微相,并进一步论述了沉积相的展布与演化规律。

Sedimentary characteristics of the Under Wuerhe Formation in the 8th Area of Karamay Oilfield were studied deeply and multiple types of facies were identified in this article by applying modern theories of sedimentology and using sufficiently data from well cores, drilling and well logging, etc, in order to explore oil and gases potentials of the Under Wuerhe Formation in the 8th area and supply some beneficial district that old well are taped the latent power, two subfacies and nine micro--facies are identified. And further discusses the distribution of the sedimentary facies and the law of evolution.
