【摘要】 EMI成像测井是20世纪末逐渐发展起来的测井新技术。对克拉玛依油田八区下乌尔禾组15口井进行了成像测井,在深入剖析了这些成像测井资料基础上,结合岩心、常规测井、地震等资料,对该区岩性、沉积构造、沉积微相、沉积演化、物源方向等进行了详细的研究。结果表明:EMI成像测井为沉积相研究提供了一种重要的手段,其可以进行岩性分析、沉积构造识别,精细划分地层岩相,确定古水流方向,解释沉积微相等。更多还原

【Abstract】 The EMI image logging is a new logging technique which is gradually developed at the end of the 20th centu- ry.In the lower Urho formation in the 8th area of Kara- may oilfield,the new technique has been applied to 15 wells.Based on further analysis of the image logging data and combined with conventional logging data and seismic data,the lithology,sedimentary structure,sedimentary microfacies,sedimentary evolution,provenance of the ar- ea have been further studied.The results indicate that this technology provided a important measure for sedimentary facies,it can apply to lithology analyse,sedimentary structure distinguish,formation lithology facies fine di- vide,paleorivers direction definite,sedimentary microfa- cies explain and so on.更多还原
