摘要： 将EMI 成像测井资料用于克拉玛依油田八区下乌尔禾组砾岩油藏沉积相研究中,弥补了因岩心的垂向不连续性、取心较短、岩心错位、破碎和漏失及无方向性等造成的某些沉积信息的漏失和错位。通过岩心的成像测井图像归位,对岩性和沉积构造的EMI 成像测井图像响应进行了研究,并首次识别出岩心资料不能识别的逆行沙波交错层理。在此基础上,对该目的层位的河控型扇三角洲各微相的成像测井响应特征进行了讨论,总结出颗粒流沉积、河道沉积、天然堤沉积、河道间沉积、泥石流和碎屑流沉积等大方向沉积微相类型的成像测井图像响应特征,其中颗粒流沉积为首次识别,而取心资料未见及。同时也讨论了EMI 成像测井资料在沉积相展布和演化及物源方向的研究中应用。

Abstract: EMI image logging technique is used for study of the sedimentary facies of Lower Wuerhe conglomerate reservoir in District No.8, Karamay oilfield, which deals with the loss and misplacement of some sedimentary information caused by the vertical discontinuity of core, short core, core break, leakage and misplacement as well as no direction of core. The characters of EMI image logging about lithology and sedimentary structure by comparison between the core data and EMI image logging data. The regressive sand wave crossbedding, which cannot be found in the core data, is identified in the studied area for the first time, based on which the features of the EMI image logging of microfacies of fluvial-dominated fan delta deposits in the target zone of District No.8 in Karamay oilfield are discussed. And the EMI image logging features of such microfacies as grain-flow deposit, channel deposit, natural levee deposit, interchannel deposit, mud-rock flow and debris flow are then presented in this paper. The grain-flow deposit is identified for the first time, which isn't found in the core data. Also, the application of EMI image logging data to the distribution and evolution of sedimentary facies and the source direction of the target zone is discussed.

Key words: Karamay oilfield, EMI image logging, sedimentary facies, fan, delta
