Detailed description of the invention
See figures.1.and.2, cross drilling rod memory-type four arm caliper logging tool, comprise top connection 1, upper cargo tank 3, gage beam assembly and lower cargo tank 14, lower contact 15.
Wherein, gage beam assembly comprises principal arm 6, lower principal arm 9, arc steel plate 7, main shaft 8, secondary spring 12 and piston rod 11, and described main shaft 8 is connected with upper cargo tank 3, is connected down with lower bunker 14; The upper end of upper cargo tank 3 is connected with top connection 1, and lower cargo tank 14 is connected with lower contact; The lower end of upper principal arm 6 is connected with the upper end of lower principal arm 9 by arc steel plate 7, the upper end of upper principal arm 6 and the lower end of lower principal arm 9 are arranged on main shaft 8, the upper end of upper principal arm 6 is installed on main shaft 8 by alignment pin, lower principal arm 9 is pacified in the chute of main shaft 8 by alignment pin activity, its lower end is connected with the upper end of piston rod 11 simultaneously, piston rod 11 outer race has secondary spring 12, and the lower end of piston rod 11 is connected with potentiometer 13 pull bar be installed in lower cargo tank 14; In lower cargo tank 14, be axially evenly distributed in four rod-pulling type active electrical potential devices 13, potentiometer 13 pull bar is threaded with piston rod 11 lower end; Lower principal arm 9 is the movable motion being driven potentiometer 13 pull bar by piston rod 11 in chute, completes the conversion of machinery to the signal of telecommunication.Axially four groups of chute (not shown)s are evenly distributed in main shaft 8 lower end, the long 280mm of chute, wide 18mm, dark 15mm, at chute built with piston rod 11 and secondary spring 12, piston rod 11 can longitudinally move up and down in chute, drives the action of pull bar potentiometer 13 with this.Described secondary spring 12 is enclosed within piston rod 11, its role is to promote lower principal arm 9 and gage beam is opened, and the moment does manual work in gage beam with the change of hole diameter.Described pull bar potentiometer 13 is installed in lower cargo tank 9, and adopt retaining ring to fix, it is parallel longitudinal in being located at the chute on main shaft 8.Upper cargo tank 6 is communicated with by the oil-through hole in main shaft 8 with lower cargo tank 9, is marked with silicone oil in it, plays the effect of lubrication, counterpressure.Lower contact 15 also comprises the cone rubber head 16 be installed on bottom.Crashproof effect is played by cone rubber head 16.
Operating principle is as follows: during well logging, and when hole diameter size diminishes, arc spring steel disc 7 opening angle can increase, lower principal arm 9 is driven to do work, piston rod 11 is moved downward, drives potentiometer 13 action, drive pull bar potentiometer 13 to obtain desired data by mechanical arm like this; When hole diameter size becomes large, its operating principle antithesis.Such 4 mechanical arms work independently, adopt the driving of arc steel plate 7, secondary spring 12 two kinds to work together and make principal arm acting strength larger, mechanical arm reaction is more fast sensitive, also can obtain satisfied log data when quick well logging, solve the generation that mechanical arm that motor drives single direction logging mode and single spring steel to drive to cause reacts slow puckery phenomenon simultaneously.
