元素录井技术就是利用X射线荧光分析仪器,分析石油钻井中的岩心、岩屑的化学元素种类和含量,并以岩石地球化学理论为指导,根据元素信息进行岩性识别和地层评价的随钻地质分析技术。本次课题对杭锦旗地区常规录井资料和测井资料进行了分析,并对该区50多口井前上古生界地层寒武-奥陶系、中元古界、太古界的岩屑进行了X射线元素分析进而利用元素特征信息识别出各地层相关岩性确立该区地层划分依据。
Element logging is the use of X-ray fluorescence analysis equipment, analysis of oil drilling in the core, the chemical elements of rock fragments and content, and the rock geochemical theory as a guide, based on the element information for lithology identification and stratigraphic evaluation of the drilling Geological Analysis Technology. This topic analyzes the conventional logging data and logging data in Hangjinqi area and analyzes the lithofacies of the Cambrian-Ordovician, Middle Proterozoic and Archaean Upper Paleozoic strata in more than 50 wells in the area X-ray elemental analysis and then use the element characteristic information to identify the lithology related to each formation to establish the stratigraphic division basis.
