Integral type test throw in catcher

Technical field:

The utility model relates to a kind of pulling and running tool used in the oil recovery field, oil field, especially integral type test throw in catcher.

Background technology:

In oil recovery field, oil field, throw in catcher is when down-hole pulling water nozzle, and in the pulling process, water under high pressure and motive power are very big to the instrument impact force, and it is loosening often to form throw in catcher bottom screw thread, causes easily that the bottom comes off to cause junk; Under the effect of power, cause that the axial prong displacement makes orientation not point-blank simultaneously because each screw is loosening, difficulty when causing the pulling water nozzle, original throw in catcher complex structure, length is long, overweight, gets the instrument difficulty at well head, exists potential safety hazard.Throw in catcher has all will be tightened each position screw before 12 each instruments of screw are gone into the well, and makes instrumentation card on tubing string to prevent that screw was loosening after throw in catcher from going into the well, and has brought inconvenience to test operation.

The utility model content:

Easily come off and baroque deficiency in order to overcome the split type connection of existing throw in catcher, the utility model provides a kind of integral type test throw in catcher, this integral type test throw in catcher adopts integral structure, has simple in structure, in light weight, long service life and characteristics easy to use.

The technical solution of the utility model is: this integral type test throw in catcher comprises throw in catcher main body, guide grab, guide grab pin and guide grab spring, the guide grab dowel fixes is on the throw in catcher main body, the throw in catcher main body is an integral structure, guide grab tilts to be hinged on the guide grab pin, between guide grab and the throw in catcher main body guide grab spring is arranged, the upper side of guide grab is close on the throw in catcher main body, and the lower end of guide grab has draws tiltedly.

The utlity model has following beneficial effect: owing to take the throw in catcher main body in the such scheme is integral structure, has avoided its back that is hit because of screw thread is loosening the bottom to be come off, long service life; Cancelled the lock wheel mechanism of the guide grab top in the background technology, original 12 screws also reduce to 4, simplify the structure, and have shortened integrally-built length, have alleviated weight, and are simple in structure, in light weight, carry with easy to use.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

1-throw in catcher main body among the figure, the 2-guide grab, 3-guide grab pin, 4-guide grab spring, 5-draws tiltedly.
