<jats:p>The resistivity logging in CBM horizontal well is under the influence of factors such as borehole, mud invasion and anisotropy. The environmental impact correction can improve the interpretation accuracy of CBM the horizontal well. This paper introduced in detail the correction methods of borehole, mud invasion and anisotropy, and the environmental impact of the resistivity logging in CBM horizontal well are automatically corrected using computer correction program. The results show that the method is easy to operate and feasible, and is highly operable. The corrected resistivity in horizontal well can approximately represent the real resistivity of the coal reservoir, which is able to improve the evaluation accuracy of the coal reservoir resistivity logging.</jats:p>
