Abstract
The utility model provides a seizing machine for testing well head of oil well and water well, which belongs to a device for testing well head of oil field oil well and water well. The seizing machine is a cylinder body with a screw thread externally at upper section; a taper cylinder body is provided under the cylinder body, which is integrated with the cylinder body; bottoms of a plurality of vertical slot holes on the cylinder body are communicated with the slot holes on the taper cylinder body which has a convex rope socket hang platform on the inner surface; the cylinder body is arranged with a limit plug through a screw thread at upper section and holes are opened at center of the plug. The well head seizing machine has the advantages of simple and rational structure, convenient assembly, large success rate for catching, high reliability, after successful catching, the machine can take off the apparatus or tools without needing disassembly but convenient operation.
Description
Technical field
The utility model provides the device on a kind of oilfield, the water well test well head, especially a kind of catcher.
Background technology
In the oil development process, need test oil, well.The instrument of G.I.H or instrument are when upwards mentioning to well head, if malfunctioning because of human negligence or counter, steel wire for logging can pull off from rope socket, cause instrument or the instrument down-hole of falling.For preventing the generation of this phenomenon, people are provided with catcher at well head.Present catcher adopts slip-type structure, and it catches rope socket by three slips that separate.When in the slips silt being arranged, easily stop up, cause and catch failure.And, the instrument of catch or instrument when this catcher takes off, must be decomposed whole catcher and come, operation is inconvenience very.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oil, water well test well head catcher, with the reliability of raising seizure and the convenience of operation.
The utility model is to realize like this, oil, water well test well head catcher, the threaded cylindrical shell of exterior upper portion is arranged on described catcher, have below the cylindrical shell and its all-in-one-piece conical shell, the bottom of a plurality of vertical slotted eye above the cylindrical shell is connected with slotted eye on the conical shell, and the rope socket hanging platform of protrusion is arranged at the inner surface of conical shell, by screw thread spacing plug is installed on cylindrical shell top, the middle part of spacing plug is porose.
Adopt oil, the water well test well head catcher of said structure, simple and reasonable for structure, simple and convenient assembly, the success rate of seizure is big, the reliability height, catch successfully after, just need not decompose can with instrument or instrument from it face take off, easy to operate.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the left view of Fig. 1.
The sectional view of Fig. 3 the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and operating principle.
As shown in drawings, on the oil of the utility model, water well test well head catcher, the threaded cylindrical shell of exterior upper portion (2) is arranged, have below the cylindrical shell and its all-in-one-piece conical shell (5), the bottom of a plurality of vertical slotted eye (3) above the cylindrical shell (2), be connected with the slotted eye (4) on the conical shell, at the inner surface of conical shell the rope socket hanging platform (7) of protrusion is arranged, by screw thread spacing plug (1) is installed on cylindrical shell top, the middle part of spacing plug porose (6).
The width of a slotted eye in the slotted eye on the conical shell should be greater than other slotted eye, and the width of this slotted eye is slightly larger than the diameter of rope socket bottom, so that catch the successfully taking-up of back rope socket.The width of a slotted eye in the vertical slotted eye (3) above the cylindrical shell (2) also should be greater than the maximum gauge of rope socket, and purpose also is to be convenient to catch the successfully taking-up of back rope socket.
During use, the screw thread of this catcher by the cylindrical shell outside is installed on the blowout prevention plug, the blowout prevention plug is installed on the well head.The steel wire for logging that connects instrument or instrument passes the middle hole (6) of spacing plug and links to each other with rope socket (8).When the instrument of G.I.H or instrument when upwards mentioning to well head, rope socket can move up along the inwall of conical shell, and cylindrical shell, the conical shell of this catcher strutted, after rope socket moves on further, will hang over above the rope socket hanging platform (7), cylindrical shell, the conical shell of this catcher close up.At this moment, even steel wire for logging is broken, the instrument or the instrument that are connected the rope socket below can not fall yet, and catch successfully.Upwards rotate instrument or instrument then, the bigger slotted eye of the width of rope socket on conical shell is upwards rotated, make rope socket vertical, at this moment the slotted eye (3) of rope socket on cylindrical shell can be taken out with this catcher.
Claims (1)
1, oil well, water well test well head catcher, it is characterized in that, the threaded cylindrical shell of exterior upper portion (2) is arranged on described catcher, have below the cylindrical shell and its all-in-one-piece conical shell (5), the bottom of a plurality of vertical slotted eye (3) above the cylindrical shell (2) is connected with slotted eye (4) on the conical shell, and the rope socket hanging platform (7) of protrusion is arranged at the inner surface of conical shell, by screw thread spacing plug (1) is installed on cylindrical shell top, the middle part of spacing plug porose (6).
