Abstract
The utility model belongs to a device used for measuring a blocked position in a drilling, which comprises a hanging device, cables, a positioning device, a weighted rod and a magnetic positioner, wherein, the positioning device is an eccentric arm which is composed of a connecting rod and an elasticity arched eccentric arm; the hanging device and the weighted rod are respectively connected with both ends of the connecting rod through universal couplings; the connecting rod is provided with a spring pretension nut and is sheathed with a sliding arm. Both ends of the eccentric arm are respectively arranged on the connecting rod and the sliding arm, a spring is arranged between the pretension nut and the sliding arm, and the magnetic positioner is connected to the weighted rod. The utility model has the advantages of simple structure, low cost, convenient operation and flexible movement in a water eye of a drilling rod.
Description
The utility model belongs to the device of measuring the blocked portion position in a kind of drilling well.
Present employed blocked portion tester, it includes erecting by overhang, cable, magnetic localizer, positioner, sensor and weighted lever, its positioner is felt relieved blocked portion tester in the drilling rod hydrophthalmia, after blocked portion tester puts down from the drilling rod hydrophthalmia, rotation or lift drilling rod, by sensor the stuck point signal is delivered to ground through cable, and with the cooperating of magnetic localizer, measure the stuck point position.Because positioner is a centring device, structure is comparatively complicated, and moves up and down dumb.And the employing sensor, cost height, inconvenient maintenance.
The purpose of this utility model is to address the above problem, provide a kind of simple in structure, cost is low, easy to operate, move up and down flexible pushing type magnetic blocked portion tester.
It includes erecting by overhang, cable, positioner, weighted lever and magnetic localizer the utility model, positioner is a telescoping ram, telescoping ram is made of connecting rod and elasticity arch backup arm, the two ends of connecting rod connect erecting by overhang and weighted lever by universal joint respectively, on connecting rod, be equipped with the spring pre-load nut, and be socketed with travelling arm, the two ends of backup arm are positioned on respectively on connecting rod and the travelling arm, elongation at backup arm is provided with spring between pre-load nut and travelling arm, magnetic localizer is connected on the weighted lever.
The utility model is simple in structure, cost is low, and is easy to operate, flexibly mobile in the drilling rod hydrophthalmia.
Fig. 1 is the utility model structural representation;
Fig. 2 is the magnetic localizer structural representation;
Fig. 3 is the A-A cutaway view Amplified image of Fig. 1;
Fig. 4 is the gimbal structure schematic diagram.
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, it includes erecting by overhang 2 the utility model, cable 1, positioner, weighted lever 12 and magnetic localizer 13, positioner is a telescoping ram, telescoping ram is made of connecting rod 4 and elasticity arch backup arm 5, the two ends of connecting rod 4 are respectively by universal joint 3,10,11 connect erecting by overhang 2 and weighted lever 12, on connecting rod 4, be equipped with spring pre-load nut 9, and be socketed with travelling arm 7, the two ends of backup arm 5 are positioned on respectively on connecting rod 4 and the travelling arm 7, elongation at backup arm 5 is provided with spring 8 between pre-load nut 9 and travelling arm 7, magnetic localizer 13 is connected on the weighted lever 12.As shown in Figure 2, magnetic localizer can adopt a pair of magnet steel 15 and one group of structure that coil 14 is formed, and to scolding, coil 14 is put in the centre two polarity of magnet steel 15, just forms a constant magnetic field.During use, adjust the pretightning force of 8 pairs of backup arms 5 of spring earlier with pre-load nut 9, also determined simultaneously the spacing of backup arm 5 with connecting rod 4, put down from the drilling rod hydrophthalmia, because the effect of backup arm, one side of the present utility model is pasted mutually with drilling rod, and this moment, the changes of magnetic field of magnetic localizer was zero, and electromotive force also is zero.When lifting movable drilling tool, because drilling tool has certain elongation and elasticity, elastic module passes on the blocked portion tester along drilling rod, because the setting of universal joint, the magnetic localizer bullet is from drilling rod, and magnetic field changes, the electromotive force of coil is delivered to ground by cable, and goes on record.When blocked portion tester during down to the stuck point position, on carry drilling tool because very little at the elastic module of stuck point place drilling tool, the displacement between magnetic localizer and the drilling rod levels off to zero, changes of magnetic field goes to zero, coil institute induced electromotive force also levels off to zero.Judge the stuck point position by contrasting up and down.
As shown in Figure 1, connecting rod 4 connects weighted lever 12 by two joint universal joints 10,11, is more conducive to blocked portion tester and moves in drilling rod.As shown in Figure 1, on connecting rod 4, be positioned on block 6, in case the thrust arm rest on push away and fracture.As shown in Figure 3, be equipped with alignment pin 16 on travelling arm 7, to having chute 17, alignment pin 16 cooperates with chute 17 in connecting rod 4 upper edge length, and travelling arm 7 is not rotated along connecting rod 4.
As shown in Figure 4, universal joint 3 is hinged on respectively up and down on the articulated body, promptly be hinged on erecting by overhang 2 and the connecting rod 4, and jointed shaft 19,20 is vertical mutually, universal joint 3 through hole 18 axially arranged, be convenient to cable 1 and pass through.Universal joint 10,11 is identical with universal joint 3 structures.
The utility model telescoping ram also can be reversed end for end structure shown in Figure 1 up and down, also can finish the purpose of this utility model.
