摘要
Based on horizontal well modeling with 3 layers,the authors analyzed the impact of borehole on dual laterolog in the horizontal well by using the 3D Finite Element Method.The numerical simulation shows that the positions of horizontal boreholes,the various borehole sizes and mud resistivity exert obvious influences on dual laterolog response,especially in the thin bed.The larger the borehole size and mud resistivity are,the more serious the impact on dual laterolog response is.Within the thickness of 6 m,the deep and shallow laterolog response in the horizontal well varies with parameters of the shoulder bed.The shoulder bed makes little impact on the deep laterolog response beyond the thickness of 36 m and on the shallow laterolog beyond the thickness of 6 m.Within the range of 15°,the dip-angle of horizontal borehole makes little impact on the dual laterolog response.
