Abstract
The utility model discloses a wireline log blowout prevention pup joint which is at least composed of an upper connector, a folio gland nut, a folio outer cone-shaped cable clip, a side opening inner cone-shaped clip sleeve, handles, a side opening cable locking device, a side opening extension joint, a first side opening and a second side opening. The upper connector is connected with a drill stem through upper threads in a threaded mode. The upper connector is connected with the upper threads of the cable locking device through lower threads. The folio gland nut, the folio outer cone-shaped cable clip and the side opening inner cone-shaped clip sleeve are arranged in the side opening cable locking device. The folio outer cone-shaped cable clip is arranged inside the side opening inner cone-shaped clip sleeve. The folio gland nut is connected with the folio outer cone-shaped cable clip. The handles are arranged outside the side opening cable locking device. Side through holes are formed in the upper connector. The side opening extension joint is arranged at the outer opening end of the side opening cable locking device. The wireline log blowout prevention pup joint has the advantages of being novel in structure, capable of quickly cutting hang and connection of logging cable and achieving sealing of fluid such as oil gas in a shaft, safe and reliable.
Description
Technical field
The utility model relates to the petroleum works field, relates in particular to the wireline logging blowout prevention nipple that relates to a kind of petroleum works Oil/gas Well.
Background technology
In with the cable during well logging, when the fluids such as oil gas in the pit shaft of Oil/gas Well were upwards gushed out, present way was to cut off logging cable, and the down-hole part is lost in pit shaft, by closing blowout preventer, realized the sealing of the fluids such as oil gas in the pit shaft; The deficiency that this operating type exists is increase difficulty and the risk that causes subsequent job.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of wireline logging blowout prevention nipple, is connected on the drilling rod of petroleum works Oil/gas Well, when being applicable to the wireline logging operation, realizes the sealing of the fluids such as oil gas in the pit shaft.
For achieving the above object, a kind of wireline logging blowout prevention nipple described in the utility model, at least by top connection, split clamp nut, split the male-tapered strain relief clamp, side opening inner conical clamp cover, handle, side opening cable locker, side opening prolong joint, the first side opening, the second side opening consists of, described top connection is connected with drill rod thread by upper screw thread, and top connection is threaded by on lower screw thread and the described cable locker; Be provided with and split clamp nut, split male-tapered strain relief clamp and side opening inner conical clamp cover in the described side opening cable locker, the described male-tapered strain relief clamp of splitting places in the side opening inner conical clamp cover, describedly splits clamp nut and splits the male-tapered strain relief clamp and be connected; Described side opening cable locker is provided with handle outward; Described top connection is provided with by-pass prot, and the collar extension end of described side opening cable locker is provided with side opening and prolongs joint.
The beneficial effects of the utility model are:
Novel structure can be finished the suspension of cutting off logging cable and the connection of drilling rod fast, realizes the sealing of the fluids such as oil gas in the pit shaft, and is safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the described wireline logging blowout prevention nipple of the utility model embodiment;
Fig. 2 is the sectional view of A-A among Fig. 1;
Fig. 3 is the sectional view of B-B among Fig. 1.
The specific embodiment
Below in conjunction with Figure of description the utility model is further described.
As shown in Figure 1, the described a kind of wireline logging blowout prevention nipple of the utility model embodiment, at least by top connection 3, split clamp nut 6, split male-tapered strain relief clamp 7, side opening inner conical clamp cover 9, handle 10, side opening cable locker 11, side opening prolong joint the 13, first side opening 15, the second side opening 16 consists of, described top connection is connected with drill rod thread by upper screw thread 1, and top connection is threaded by on lower screw thread 5 and the described cable locker; Be provided with and split clamp nut, split male-tapered strain relief clamp and side opening inner conical clamp cover in the described side opening cable locker, the described male-tapered strain relief clamp of splitting places in the side opening inner conical clamp cover, describedly splits clamp nut and splits the male-tapered strain relief clamp and be connected; Described side opening cable locker is provided with handle outward; Described top connection is provided with by-pass prot 2, and the collar extension end of described side opening cable locker is provided with side opening and prolongs joint.
Because the glue heart of blowout preventer can only sealing drilling rod, can't sealed logging cable 12, the cable bottom is connected with logger 14.When the fluids such as oil gas in the pit shaft are upwards gushed out, buttress handle 10, logging cable 12 is inserted on side opening cable locker 11 and the side opening inner conical clamp cover 9 from the first side opening 15, the second side openings 16; Logging cable 12 is enclosed within splits in the male-tapered strain relief clamp 8, split male-tapered strain relief clamp 8 and put into side opening inner conical clamp cover 9, tighten on side opening inner conical clamp cover 9 splitting clamp nut 6, side opening inner conical clamp cover 9 is put into side opening cable locker 11; When logging cable 12 moves down, split male-tapered strain relief clamp 7 and move down simultaneously, be locked in the side opening inner conical clamp cover 9, realize the suspension of logging cable 12.Cut off mouthful 4 positions at logging cable and cut off cable, the upper screw thread 1 of top connection is connected with drill rod thread, the lower screw thread 5 of top connection is connected with screw thread 8 on the cable locker, the glue heart of drilling rod by blowout preventer, close blowout preventer, realize the sealing of the fluids such as oil gas in the pit shaft, avoid the cable well that falls to increase difficulty and the risk of subsequent job, priorly avoid occuring gas blowout accident.
Design philosophy of the present utility model may extend on the wireline logging blowout prevention nipple of any model.Material property, crudy, thermal treatment quality and assembly quality should be guaranteed in the specific implementation, only in this way just reliability of the present utility model and high life can be guaranteed.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
