Abstract
A kind of multi-functional well logging salvaging instrument, comprise, urceolus and the top connection be threaded with urceolus, in top connection upper end, fishing neck is set, it is characterized in that: described urceolus is connected with bailer grab slide block, mandrel is fixed on outer barrel with cutting off, outside mandrel, be set with main spring, its main spring one end apical grafting mandrel pressure cap, other end apical grafting urceolus port part; In the outer cover of urceolus, secondary spring is housed, its secondary spring one end apical grafting top connection, other end apical grafting bailer grab.This instrument, in oil reservoir logging salvaging process, fully achieves the function of freely giving up.Tool string can be made to discharge in precalculated position, solve again when card met by instrument simultaneously and break the accidents such as cable by force.Ensure that fishing tool under stuck state together, can use bumper jar that cutting off of this instrument is cut off, this instrument and downhole instrument string are slipped out of the hand, thus eliminate and tie down Construction traffic at well head, be conducive to accident settlement.
Description
Technical field
The utility model relates to a kind of multi-functional well logging salvaging instrument, belongs to the technical field of oil reservoir logging fishing tool aspect.
Background technology
The oil field development middle and later periods, oil water well test work is more and more important, but because downhole conditions becomes increasingly complex, make test job Instrumental increasing by the probability of card, fishing tool in the past exists salvages one-way, namely fishing tool cannot be thrown off after salvaging instrument string again, if take the method for haling cable puller, cable can be caused to pull off, cause down-hole accident complicated, have a strong impact on downhole safety, increase cost simultaneously.
Summary of the invention
For the deficiency that the problems referred to above exist, the purpose of this utility model is, provides a kind of multi-functional well logging salvaging instrument.
A kind of multi-functional well logging salvaging instrument, comprise, urceolus and the top connection be threaded with urceolus, in top connection upper end, fishing neck is set, it is characterized in that: described urceolus is connected with bailer grab slide block, mandrel is fixed on outer barrel with cutting off, outside mandrel, be set with main spring, its main spring one end apical grafting mandrel pressure cap, other end apical grafting urceolus port part; In the outer cover of urceolus, secondary spring is housed, its secondary spring one end apical grafting top connection, other end apical grafting bailer grab.
Described mandrel pressure cap lock-screw is fixed on mandrel.
The beneficial effects of the utility model: this instrument, in oil reservoir logging salvaging process, fully achieves the function of freely giving up.Tool string can be made to discharge in precalculated position, solve again when card met by instrument simultaneously and break the accidents such as cable by force.Ensure that fishing tool under stuck state together, can use bumper jar that cutting off of this instrument is cut off, this instrument and downhole instrument string are slipped out of the hand, thus eliminate and tie down Construction traffic at well head, be conducive to accident settlement.This instrument has larger promotional value in oilfield test well logging.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: top connection 1, mandrel pressure cap 2, main spring 3, mandrel 4, urceolus 5, secondary spring 6, slide block 8, lock-screw 9, cut off 10.
Detailed description of the invention
As shown in Figure 1, a kind of multi-functional well logging salvaging instrument, comprise, urceolus 5 and the top connection 1 be threaded with urceolus 5, arrange fishing neck in top connection 1 upper end, it is characterized in that: described urceolus 5 is connected with bailer grab 7 slide block 8, mandrel 4 is fixed on urceolus 5 inside with cutting off 10, is set with main spring 3, its main spring 3 one end apical grafting mandrel pressure cap 2 outside mandrel 4, other end apical grafting urceolus 5 port part, described mandrel pressure cap 2 is fixed on mandrel 4 with lock-screw 9.Outside urceolus 5, be set with secondary spring 6, its secondary spring 6 one end apical grafting top connection 1, other end apical grafting bailer grab 7, bailer grab 7 is in punctured position under the effect of secondary spring 6.
When salvaged instrument enters urceolus, make bailer grab up, due to the ramp effect of urceolus 5 and bailer grab 7, make bailer grab outwards open the fishing neck catching instrument, thus realize the object of fishing tool.When salvaging process is hampered or has salvaged, make to cut off 10 with outer jarring force and cut off, because the power of main spring 3 is much larger than secondary spring power 6, makes mandrel 4 up, slide block 8 is pulled, bailer grab is opened, this fishing tool and downhole instrument string are slipped out of the hand.
Claims (2)
1. a multi-functional well logging salvaging instrument, comprise, urceolus and the top connection be threaded with urceolus, in top connection upper end, fishing neck is set, it is characterized in that: described urceolus is connected with bailer grab slide block, mandrel is fixed on outer barrel with cutting off, outside mandrel, be set with main spring, its main spring one end apical grafting mandrel pressure cap, other end apical grafting urceolus port part; In the outer cover of urceolus, secondary spring is housed, its secondary spring one end apical grafting top connection, other end apical grafting bailer grab.
2. the multi-functional well logging salvaging instrument of one according to claim 1, is characterized in that: described mandrel pressure cap lock-screw is fixed on mandrel.
