摘　　要：塔里木油田柯东地区储层以低孔低渗、特低孔低渗为特征,且孔隙结构复杂,裂缝发育,导致测井识别和评价存在极大的困难。通过对该区上白垩统库克拜组(K2k)气层测井解释研究,在试验资料分析的基础上,利用岩心分析数据和目的层段可靠的测井信息,建立物性(孔隙度、渗透率)、饱和度参数测井解释模型,分析裂缝性砂岩的有效性,绘制测井解释图版,提高对油气水层的识别能力。研究成果不仅具有很强的理论意义,还具有重要的实用价值。In Kuqa Area,the reservoir features were low porosity and low permeability and ultra-low porosity and permeability,the reservoir pore-structure was complex with fracture development,it caused great difficulty for evaluation.Through studying the logging interpretation data from Kukebai Gas Well in Kedong Area of Tarim Oilfield and on the basis of analyzing the test data,a physical property(porosity,permeability),and saturation parameter logging interpretation model was established by using core analysis data and reliable logging data from the target zones for analyzing the effectiveness of fractured sandstones and drawing well logging interpretation charts of oil and gas reservoir in Tarim Oilfield,by which the ability of logging identification was improved.The result of the study has great significance and adaptability in oilfield operation.
