Abstract
The utility model discloses a kind of special joint for reinforcing oil well emptying water supply rotary hose, including the first joint, the second joint and the 3rd joint being spirally connected successively；Three joints are hollow connector, are internally formed through hole；First joint is provided with external screw thread away from the second tip side, matches with well cementation pressure fan pipe joint；3rd joint seals away from O-ring seals are provided with inside the second tip side for being formed with rotary hose.The special joint can empty the residual liquid in rotary hose after the completion of well cementation by simple operations, effectively extend the service life of rotary hose.
Description
Technical field
Oil drilling drillng operation aid field is the utility model is related to, is used for reinforcing oil well more particularly to one kind
Empty the special joint of water supply rotary hose.
Background technology
In well cementing operation such as surface pipe well cementation, intermediate casing cementing, production string well cementation, cement squeeze work, mud of fetching water
When filling in the field operation such as operation, the well cementation water that uses needs to be sent to water at water source by rotary hose using immersible pump of cementing the well
Cementing concrete truck, meet cementing operation.Rotary hose one end is connected with immersible pump, the water tank water inlet of the other end and cementing concrete truck
Joint connects.After the completion of well cementing operation, immersible pump is put forward from water source, rotary hose both ends are taken apart, generally, is unloaded
Under rotary hose in containing remaining water.Traditional method is that remnants water or decoction are rided out on well site, then withdraws water
Tengential belt.More or less residual liquid be present inside rotary hose, after the completion of winter well cementing operation, the residual liquid in rotary hose is quickly
Ice is just frozen into, has a strong impact on the service life of rotary hose.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of for the special of reinforcing oil well emptying water supply rotary hose
With joint, it can empty the residual liquid in rotary hose after the completion of well cementation by simple operations, effectively extend rotary hose
Service life.
Therefore, the technical solution of the utility model is as follows：
It is a kind of for reinforcing oil well emptying water supply rotary hose special joint, including be spirally connected successively the first joint, second
Joint and the 3rd joint；Three joints are hollow connector, are internally formed through hole；First joint is away from the second tip side
Provided with external screw thread, match with well cementation pressure fan pipe joint；3rd joint is close away from O shapes are provided with inside the second tip side
Seal, sealed for being formed with rotary hose.
It is preferred that it is six prismatics that the outer surface of first joint is local, it is easy to spanner screens, the convenient behaviour for installing, dismantling
Make.It is further preferred that six prismatic is located at the middle part of first joint.
The beneficial effects of the utility model are：Water remaining in rotary hose after cementing operation is discharged into specified location, arranged
Net each pipeline raffinate, is not discharged arbitrarily on well site, can be emptied the water inside rotary hose especially after winter cementing operation, be prevented
Only raffinate pollution environment, safety and environmental protection is again antifreeze, extends rotary hose service life, reduces well cementation cost, uses manpower and material resources sparingly, ties
Structure is simple, easy to use, sealed reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the special joint provided by the utility model that water supply rotary hose is emptied for reinforcing oil well
Figure.
Embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in figure 1, a kind of special joint for reinforcing oil well emptying water supply rotary hose, including first to be spirally connected successively
Joint 1, the second joint 2 and the 3rd joint 3；Three joints are hollow connector, are internally formed through hole；First joint 1
External screw thread is provided with away from the end of the second joint 2, is matched with well cementation pressure fan pipe joint；3rd joint 3 connects away from second
O-ring seals 4 are provided with inside first 2 end, are sealed for being formed with rotary hose.
It is preferred that it be six prismatics 5 that the outer surface of first joint 1 is local, it is easy to spanner screens, convenient installation, dismantles
Operation.It is further preferred that six prismatic 5 is located at the middle part of first joint 1.
After cementing operation completion, only rotary hose and the pin thread of cementing concrete truck water tank inlet end are taken apart, by this pin thread
The 3rd joint of the special joint is inserted, the first joint is connected with well cementation pressure fan pipe joint, opens blower fan, air-flow is special through this
With rotary hose is entered after joint, residual liquid is blown in rotary hose, is returned to water source, is now pulled down rotary hose again, is preserved, will not
Well site ground is polluted.Meanwhile during use in winter, avoid residual liquid and frozen in rotary hose, influenceing rotary hose makes
The problem of with the life-span.
