| 摘 要： | 地层电阻率是影响油气评价的重要参数,感应测井是确定水平井中地层电阻率的常用方法。在实际测井环境中,地层上、下界面往往是不平行的,在测井解释过程中,这种非平行界面地层环境对水平井感应测井响应的影响是一个值得关注的问题。基于三维数值模式匹配法,通过正演数值分析,研究了地层界面倾斜时界面倾角、地层厚度、围岩电阻率、侵入带电阻率和侵入深度等对水平井双感应测井响应的影响。结果表明,在水平井中,地层界面倾斜对双感应测井响应具有一定的影响,其影响程度的大小与界面倾角有关。在非平行界面地层中,所得结论可为水平井双感应测井解释校正提供一定的理论参考。 |

| Abstract: | Formation resistivity is a very important parameter influenced on oil and gas evaluation,and dual induction logging is a usual logging technology to measure the formation resistivity in horizontal well.As the formation boundaries are often unparallel in the actual logging,it should be concerned to the influence of unparallel boundary bed on dual induction logging response in horizontal well.Based on the 3D numerical mode-matching（NMM） method and through the forward modeling numerical analysis,this paper discussed the influence factors on dual induction logging response in horizontal well,such as dip angle of boundary bed,formation thickness,resistivity of surrounding rock and invaded area,etc.The results show that the unparallel boundary has certain effects on dual induction logging in horizontal well and the degree of influence is related to the dip angle of boundary bed,which can provide some theoretical references for correction of dual induction logging in horizontal well. |
