摘要
低电阻率油气层属于非常规储集层,其常规测井响应特征不明显,难以识别与评价。针对此情况,在探讨渤海湾地区低电阻率油气层5种成因类型和简介其识别与评价思路的基础上,阐述了应用气测录井、地化录井、定量荧光录井等录井技术结合微侧向电阻率与自然电位和地层流体分析等方法识别与评价低电阻率油气层的方法和途径,给出了应用不同手段分析的参数及其特征。在渤海湾地区B1井和B2井的应用表明,该综合分析法可有效识别与评价低电阻率油气层。
The low resistivity oil and gas reservoirs belong to nonconventional reservoirs,in which the conventional wireline logging responses are not evident.According to such a condition, on the basis of discussing 5 origin types and brief introduction of their distinguishing and evaluating thought for low resistivity oil and gas reservoirs in Bohai Bay region, the authors stated the methods and ways of distinguishing and evaluating low resistivity oil and gas reservoirs by applying gas logging,geochemical logging,quantitative fluorescence logging combined with micro lateral resistivity with spontaneous potential and formation fluid analysis,and provided the parameters and their characteristics analyzed by different means.It was showed by the application in Wells B1 and B2 in Bohai Bay region that the comprehensive analysis method can be used to distinguish and evaluate low resistivity oil and gas zones effectively.
