Firstly

we established a 3D forward model of the vertical well when drilling in faults

the response of the array lateral logging was numerically simulated by the finite element method. And then

we analyzed the effects of different fault dip angles

fault distances

and surrounding rock conductivity on the characteristics of array lateral logging response in the drilling process of fault. The results showed that when in the drilling process of the fracture zone

the larger the fault dip angle was

the smaller the width of the fracture zone would be reflected by the apparent resistivity. As the array lateral logging equipment went deeper and the fault distance（≤4 meters） got greater

the measured apparent resistivity would be closer to the resistivity of the fractured zone and surrounding rocks. When under the same detection mode

the apparent resistivity would increase with the increasing of the resistivity of lower surrounding rocks. When the detection mode and the surrounding rock resistivity were the same

the apparent resistivity would decrease with the increase of the resistivity of the surrounding rock while drilling the footwall of fault.
