| description | The utility model relates to an outer pipe structure of a micro-resistivity imaging logging instrument. The outer pipe structure comprises a pipe body. The prismatic pipe is used for replacing a circular pipe, and if the circular pipe is selected, the outer contour of the pipe is tangent to the inner edge of the limited space, and the wall thickness of the pipe wall is equal to the difference between the outer diameter and the inner diameter of the pipe main body due to the fact that the maximum radial length of the pipe main body is fixed in the limited space. If a prism-shaped pipe is selected, the multiple side faces of the pipe abut against the inner contour of the limited space, and therefore the pipe wall of the pipe is thickened compared with the pipe wall of a round pipe in the limited space. And the tensile resistance, compression resistance and bending resistance of the cable are naturally enhanced. The through hole is used for facilitating the hydraulic fluid in the hydraulic assembly to enter the |
