Dislocated support-type centering guide for cased well logger

The invention discloses a dislocated support-type centering guide for a cased well logger. The dislocated support-type centering guide for the cased well logger is characterized in that support arms, ejector rods, springs and socket sleeves are adopted to form a lever structure. When the inner diameter of a casing pipe is slightly changed, the support arms rotate, forces received by the springs are not changed much, and moment arms of the springs are nearly unchanged, so that support forces of rollers are nearly unchanged by the buffering and the compensation of lever mechanisms; all rollers are centripetally arranged, so that the centering performance of the centering guide is better; two sets of centering arms are dislocated in an axis direction, so that the centering guide is more stable, and can more easily overcome obstacles. A positioning boss located on a center rod is capable of preventing the phenomenon that the support arms at both sides of each roller are damaged due to the fact that the support arms are excessively close, and meanwhile, the positioning boss also plays a role of limiting the sliding socket sleeves. The dislocated support-type centering guide for the cased well logger disclosed by the invention is suitable for casing pipes of various specifications. By rotating threads between glands and slide carriages, the length of an inner gap between each socket sleeve and the corresponding gland is adjusted to control magnitudes of the forces of the springs, and therefore, the magnitudes of the support forces can be adjusted according to the size of the inner diameter of the casing pipe in actual logging operations.
