摘　　要：准噶尔盆地西北缘侏罗系砂砾岩次生稠油油藏埋藏浅、分布面积广。通过九区南部齐古组油藏钻井取心、试油、试采资料与电测曲线对比,证实低电阻率油层存在。在大量岩心观察描述的基础上,利用测井曲线综合分析,结合储层岩性、物性、电性及含油性这“四性”关系研究及油藏地质综合分析,开展低电阻率油层影响因素分析。分别从平面上和纵向上对低电阻率油层的分布规律进行研究,最终达到识别低电阻率油层的目的。In the northwest Jurassic system in Zhungeer Basin there are widely distributed shallow secondary glutinite inspissated reservoirs. Comparisons among core data, oil and well testing data along with resistivity log data have approved the existence of the low resistivity oil layers in Qigu group in the ninth area of Kalamayi oilfield. On the basis of many core data and log data analyses, detailed are reservoirs lithology, physical property, electric property and oil-bearing property in this area, from which we found the “four-property” mentioned above have obvisous effects on the low resistivity layers, and the oil-bearing property is the main effect on the layers. The layers in this area distribute horizontally and vertically.
