摘要/Abstract

摘要： 随着勘探节奏的加快,录井对储层的快速、准确评价变得更加重要,为了充分挖掘油气水层录井解释的数据优势,克服录井技术只能定性或半定量判断流体性质的缺点,提高录井对油水层识别的准确性,优选对储层含油性更敏感的含油饱和度和孔隙度参数,利用录井参数通过多元线性回归方法建立了其定量计算模型,用于快速、准确地识别地层流体性质。该方法在渤海海域X油田的应用中,油水层解释符合率达到81%,使及时发现油气显示的效果明显提升,增强了综合录井在现场的使用价值。

关键词: 录井参数, 含油饱和度, 孔隙度, 多元线性回归, 油水层

Abstract: With the acceleration of exploration pace, the rapid and accurate evaluation of reservoirs by mud logging has become more important. In order to fully explore the data advantages of mud logging in the interpretation of oil, gas, and water layers, overcome shortcomings of logging technology that can only qualitatively or semi quantitatively determine fluid properties, and improve the accuracy of identifying oil and water layers during mud logging, a quantitative calculation model is built by selecting oil saturation and porosity parameters that are more sensitive to reservoir oil content, and using mud logging parameters, which can quickly and accurately identify formation fluid properties. In the application of this method in the X oilfield in the Bohai Sea area, the accuracy rate of oil and water layer interpretation reached 81%. It significantly improved the display effect of oil and gas discovery and enhanced the practical value of comprehensive logging in the field.

Key words: logging parameter, oil saturation, porosity, multiple linear regression, oil and water layers
