地层电阻率各向异性可分为宏观各向异性和微观各向异性,实际生产中常见的是砂泥岩薄互层中的宏观各向异性。本文通过分析HD4油田2口水平井井眼轨迹与地层之间关系,模拟出地层的视电阻率与导眼井实际测量电阻率对比,并模拟出各向异性系数,发现各向同性地层中能借用直井的饱和度解释模型处理水平井的测井资料。 Formation resistivity anisotropy can be divided into macroscopic anisotropy and micro anisotropy, the actual production is common in sandstone shale interbedded macroscopic anisotropy. By analyzing the relationship between the wellbore trajectories of two horizontal wells in HD4 oilfield and the strata, this paper simulates the apparent resistivity of the strata and the actually measured resistivity of the pilot well and simulates the anisotropy coefficient. It is found that the isotropic strata can borrow Vertical Well Saturation Interpretation Model to Process Well Logging Data.
