Abstract
A prtial-dynamic corbel piece log tool is characterized in that the log tool consists of a rod body and more than three corbel pieces around the rod. One end of each corbel piece is connected with each signaling gear. Except for the silo and the well with low slop, the log tool can also measure the well diameter and terrane resistance of the artesian wells such as the level well, the well with large slop and the deformation well.
Description
The utility model belongs to a kind of drilling measuring instrument.
Be used at present the logging instrument that the hole diameter and the rock stratum resistance of drilling wells such as oil field are measured is the support arm linkage structure, be that an one support arm shrinks all contractions simultaneously of other support arm, when it uses in horizontal well, high angle hole or distortion well, owing to influenced by instrument gravity or projection rock, when an one support arm shrinks, other support arm all shrinks simultaneously, measures inaccurate or mistake thereby cause, and it only is applicable to vertical shaft and little gradient well.
The purpose of this utility model provides a kind of support arm partition type logging instrument that also can measure hole diameter such as horizontal well, big inclined shaft and distortion well and rock stratum resistance except that vertical shaft and little gradient well.
The utility model be achieved in that it by around the body of rod and the body of rod three constitute with upper branch arm, an end of each support arm links to each other with signaling gear separately respectively.
Technique effect of the present utility model is: except that vertical shaft and little gradient well, it also can measure the hole diameter and the rock stratum resistance of drilling wells such as horizontal well, big inclined shaft and distortion well.
Accompanying drawing is the utility model example structure schematic diagram.
Embodiment: as shown in the figure; it is made of three support arms around the body of rod and the body of rod; one end of each support arm links to each other with signaling gear separately respectively; the body of rod is linked to each other with thread protector 16 by helmet 1, center-pole 2, protective sleeve 14, main body 15 successively and forms; support arm is linked to each other with steel plate sliding seat 8 by steel plate holder 3, bearing pin 4, upper steel plate 5, steel spring plate 6, lower steel plate 7 successively and forms, and each signaling gear is linked to each other with potentiometer 13 by pull bar 9, spring 10, slide head 11, potentiometer seat 12 successively and forms.
