Abstract
The utility model discloses a kind of ocean union, comprise straight tube and joint, straight tube two ends are respectively recess and plush copper, and joint is arranged at plush copper, are provided with the connecting portion of protrusion bottom described joint, and described connecting portion comprises connecting rod and card base; Described straight tube plush copper place is provided with the link slot coordinated with connecting portion, and described link slot is divided into crank-guide way and draw-in groove; Described joint connecting rod place is provided with the holddown groove that arrange corresponding to straight tube link slot; Described joint is inner is provided with sealing ring with straight tube junction; Be that card base is connected together mode by the formatting of original nipple, reduce the abrasion deformation of original mouth of pipe junction screw thread, reduce the unnecessary damage in installation process, reduce operating cost.
Description
Technical field
The utility model relates to a kind of union, particularly relates to the union of offshore oil pipe.
Background technology
Casing string is the important component part in oilfield prospecting developing, plays an important role to the exploitation of Oil/gas Well.Casing string is the high-pressure bottle of thousands of meters of growing up be threaded connection by petroleum casing pipe one by one, and connection of thread is joint.Research shows, joint be the weakest in whole casing string, be also hold flimsy position most, therefore require that joint has higher bonding strength and good sealing performance.But the API that current joint great majority adopt is threaded, this defects such as there is bonding strength is low, poor sealing performance that is threaded.
In order to improve hermetic seal and the reliability of these joints, employ special joint in a large number.Special joint on market is only provided with a radial shape metallic leak-proof structure or elastic rubber ring, uses practice to show that its reliability is lower, and go into the well after using and very easily occur leakage phenomenon, sealing performance is low.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of ocean union.
For achieving the above object, the utility model adopts following technical scheme: a kind of ocean union, comprises straight tube and joint, straight tube two ends are respectively recess and plush copper, joint is arranged at plush copper, is provided with the connecting portion of protrusion bottom described joint, and described connecting portion comprises connecting rod and card base; Described straight tube plush copper place is provided with the link slot coordinated with connecting portion, and described link slot is divided into crank-guide way and draw-in groove; Described joint connecting rod place is provided with the holddown groove that arrange corresponding to straight tube link slot; Described joint is inner is provided with sealing ring with straight tube junction.
Described joint card base width is less than straight tube link slot width.
Described joint connection at least 3, is evenly arranged at bottom joint.
Compared with prior art, the beneficial effect had is:
Be that card base is connected together mode by the formatting of original nipple, reduce the abrasion deformation of original mouth of pipe junction screw thread, reduce the unnecessary damage in installation process, reduce operating cost.
