| description | The invention discloses a cable logger centralizer and a cable logger centralizing method. The cable logger centralizer comprises a barrel and at least two rollers, wherein the barrel sleeves and is positioned on the periphery of a cable logger; the rollers are used for being in contact with an oil well wall; mounting positions are respectively arranged on two opposite outer side surfaces of the barrel body; and the rollers are respectively matched and connected to the mounting positions. And the roller can rotate relative to the cylinder body and can roll along the inner surface of the oil well wall to drive the cylinder body and the cable logging instrument to move along the oil well wall. Sliding friction between the cable logging instrument and an oil well wall can be changed into rolling friction, the friction resistance of the cable logging instrument in a well is reduced, the well entering requirement of the cable logging instrument can be met under the working conditions of a highly-deviated well and |
