Abstract
A logging cut-and-thread fishing cable dropping preventive device relates to the technical field of cut-and-thread operation of blocked cables of oil logging tools. The logging cut-and-thread fishing cable dropping preventive device comprises stoppers, a cable locking clamp part is arranged above the stoppers, the inner diameter of each stopper is smaller than the outer diameter of the cable locking clamp part, the cable locking clamp part comprises a lower connecting sleeve, a frustum-shaped lower center hole is disposed in the lower connecting sleeve, two semi-conical sleeves are disposed in the frustum-shaped lower center hole, the upper end of the lower connecting sleeve is connected with an upper connecting sleeve in a threaded manner, an inner bottom is disposed inside the upper end of the upper connecting sleeve and arranged above the two semi-conical sleeves, and an upper center hole is arranged at the inner bottom and is coaxial with the lower center hole. During usage, a cable penetrates through the center holes of the upper connecting sleeve and the lower connecting sleeve, the semi-conical sleeves are placed in the lower connecting sleeve, the upper and lower connecting sleeves are connected in a threaded manner, and screw thread is screwed tightly so that the cable is tightly pressed by the cable and cannot move. A plurality of stoppers are placed at male and female joints of a drill stem, thereby preventing the cable and the locking clamp part from dropping in a well.
Description
Technical field
The utility model relates to oil well logging instrument and meets card cable punching fishing technical field.
Background technology
During the well logging construction operation, because the influence of factors such as drilling engineering, mud property, geological condition, well, it is unpractical avoiding various down-holes fault fully, and the downhole instrument that takes place often to log well is hampered and meets the card phenomenon.When the generation downhole instrument is stuck, must select the cable punching to salvage construction, sometimes take place in operation process that fast connector comes off and cable comes off at the connector place, cause cable all to fall into the accident of drilling rod, more complicated salvaging cable handling operation should be carried out, also bigger economic loss will be caused.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of well logging punching to salvage anti-cable dropping device, can preventing that cable from falling into the down-hole.
The purpose of this utility model is achieved in that the anti-cable dropping device of well logging punching salvaging, comprises stopper, and the top of stopper is provided with the cable locking fastener, and the internal diameter of stopper is less than the external diameter of cable locking fastener; Described cable locking fastener comprises lower joint sleeve, centre bore under the taper type is set in the lower joint sleeve, two semicircle tapered sleeves are set in the centre bore under the taper type, the upper end of the described lower joint sleeve upper joint sleeve that is threaded, the interior end, be set in the upper end of upper joint sleeve, the interior end, be arranged on the top of two semicircle tapered sleeves, and the interior end is provided with centre bore, and last centre bore and described centre bore down are arranged on the same axis.
During use, cable is passed the centre bore of lower joint sleeve, put into the semicircle tapered sleeve in lower joint sleeve, last lower joint sleeve is by being threaded, and tightens screw thread and the half-conical cover is compressed cable can not allow it move.The anti-mobile pulling force of cable locking reaches more than 5 tons.Stopper is just like trunnion, its internal diameter is less than the external diameter of cable locking fastener, the cable punching on cable locking fastener top salvage that fast connector comes off or cable after the connector place comes off, just can take out cable as long as drilling rod carried to the position that is placed with stopper, again carry out cable punching refloating operation construction operation, the combination of stopper and cable locking fastener is taken precautions against cable effectively and is fallen in the well.Damper arrangement can be laid at the drill pipe box and pin place arbitrarily, can in cable punching fishing process, select the different degree of depth to lay a plurality of stoppers, after the generation cable falls well, drilling rod is carried to nearest stopper place, just can be taken out cable head, reduce the cable punching and salvage the construction operation time.The utlity model has simple in structurely, use flexible to operationly, advantage such as the set-up time is short has been filled up the blank on the security precautions technology of this accident treatment construction operation of logging community.
The internal diameter of stopper of the present utility model is less than the external diameter of lower joint sleeve.
As improvement of the present utility model, between the interior end and two semicircle tapered sleeves the adjustment pad is set.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the reference figure of the utility model use occasion.
Among the figure, 1 upper joint sleeve, the end in the 1-1, centre bore on 2,3 adjust pads, 4 semicircle tapered sleeves, 5 lower joint sleeves, 6 times centre bores, 7 stoppers, 8 derricks, 9 top sheaves, 10 snap joints, 11 drilling rods, 12 fishing sockets, the 13 well instruments that fall, 14 cable locking fasteners.
The specific embodiment
As shown in Figure 1, salvage anti-cable dropping device for the well logging punching, comprise stopper 7 and cable locking fastener 14, stopper 7 is arranged on the below of cable locking fastener 14, cable locking fastener 14 comprises lower joint sleeve 5, and the internal diameter of stopper 7 is less than the external diameter of lower joint sleeve 5.Centre bore 6 under the taper type is set in the lower joint sleeve 5, two semicircle tapered sleeves 4 are set in the centre bore 6 under the taper type.The upper end of lower joint sleeve 5 upper joint sleeve 1 that is threaded, end 1-1 in being provided with in the upper end of upper joint sleeve 1, interior end 1-1 is arranged on the top of two semicircle tapered sleeves 4, between interior end 1-1 and two the semicircle tapered sleeves 4 adjustment pad 3 is set.Interior end 1-1 is provided with centre bore 2, and last centre bore 2 is arranged on the same axis with following centre bore 6.
As shown in Figure 2, derrick 8 is installed on the ground, the lower end of derrick 8 connects lower sheave 15, and the upper end of derrick 8 connects top sheave 9.At first downhole cable is passed the centre bore of lower joint sleeve 5, in lower joint sleeve 5, put into semicircle tapered sleeve 4, make upper joint sleeve 1 pass downhole cable then, and upper joint sleeve 1 is threaded with lower joint sleeve 5 tighten.The upper end of downhole cable connects aboveground cable by snap joint 10, and the other end of aboveground cable connects winch through lower sheave 15 more again through top sheave 9.11 is drilling rod, lays stopper 7 in drilling rod 11 pin and box subs place, and the lower end of drilling rod 11 connects fishing socket 12, and cable locking fastener 14 is stuck in stopper 7 places can not fall into the down-hole, and 13 are the well instrument that falls.
