在岩心观察基础上,运用地质、测井等资料,从单井相分析入手,通过连井对比剖面扩大到全区范围,研究了克拉玛依油田六区克下组的储层特征和砂砾岩展布规律。克拉玛依油田六区克下组为退积型冲积扇相沉积,六区为单一扇体的一部分。识别出克下组扇顶、扇中和扇缘亚相的分布,分析了各亚相的储层特征和砂体展布规律。研究表明,扇顶、扇中和扇缘亚相储层的总体岩性分别为砾岩、细砾岩和粗砂岩、中细砂岩。砂体的平面展布形式分别为连片状、宽带状和窄条状。
Based on the observation of core, using the data of geology and logging, starting from single-well facies analysis, through the extension of the continuous well section to the whole area, the reservoir characteristics and conglomerate distribution of Kexia Formation in the six districts of Karamay Oilfield law. The Kelamayi oil-field six districts of Kexia Formation is a retrograde alluvial fan deposition, and the six districts are a part of a single sector. The distributions of subfacies in fan, fan and fan edges in the Lower Cretaceous are identified. The reservoir characteristics of each subfacies and the distribution of sand bodies are analyzed. The study shows that the overall lithology of Fan, Fan and Fan sub-facies reservoirs are conglomerate, fine conglomerate, coarse sandstone and middle-fine sandstone, respectively. The plane distribution of sand bodies are contiguous, broad band and narrow band.
