Big threat.How quick, safety when typhoon to withdraw, how typhoon quickly resumes production after disappearing, most important.
Summary of the invention
Therefore, the purpose of the present invention is to provide it is a kind of it is easy to use, hanging capacity is strong, the phase can be withdrawn ensureing typhoon
Between underground work safety under the premise of, it is easier to, more quickly handle down-hole equipment, resume production drilling rod emergency suspension dress
It sets and method.
To achieve the goals above, a kind of drilling rod of the invention emergency suspension arrangement, including quick tieback sub, preventer
Suspension joint, circulating connection and double pin ends, the quick tieback sub are connected to the upper end of the preventer suspension joint,
The circulating connection is connected to the lower end of the preventer suspension joint, and double pin ends are connected under the circulating connection
End；Eaves corresponding with pit shaft protective device upper inner structure is provided on the lateral wall of the circulating connection, the eaves is taken
In the pit shaft protective device；The preventer suspension joint includes cylinder neck, is provided with shoulder on the cylinder neck, described
Cylinder neck is held tightly for preventer.
Several return holes are provided on the circulating connection.
Screw thread is sealed by low torque between the quick tieback sub and the preventer suspension joint to be connected.
The pit shaft protective device is set to the inside of high-pressure well mouth, is provided with set below the pit shaft protective device
Pipe hanger hangs the region of connecting portion close to the pit shaft protective device and described sleeve pipe in the inside and being located at of the high-pressure well mouth
It is provided with seal assembly.
Low pressure well head is provided on the outside of the high-pressure well mouth.
The present invention also provides a kind of drilling rod emergency hanging methods, are grasped using foregoing drilling rod emergency suspension arrangement
Make, comprising the following steps: jointed rod, quick tieback sub, preventer suspension joint, circulating connection and double pin ends are simultaneously sent
To high-pressure well mouth, circulating connection is ridden in pit shaft protective device, closes one group of preventer, so that preventer is embraced preventer outstanding
Cylinder neck among hanging joint, rotation drilling rod separate quick tieback sub with preventer suspension joint, pull out of hole, close another group
Preventer has continued to be drilled into turntable surface.
By adopting the above technical scheme, drilling rod emergency suspension arrangement of the invention and method, compared with prior art, have with
It is lower the utility model has the advantages that
1, operation is simple, seals screw thread phase by low torque between quick tieback sub and preventer suspension joint
It even, can be with quick separating, quick tieback；
2, complex situations can be successfully managed, are provided with multiple heavy caliber return holes, on circulating connection to establish at circulation
Manage shaft bottom complex situations；
3, it avoids and directly hangs drilling rod on preventer；
4, avoid precisely operated using needs such as packer, hangers, to presser sensor, to the conditional work of discharge capacity
Tool.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of drilling rod emergency suspension arrangement of the invention.
In figure: the quick tieback sub of T1-, T2- preventer suspension joint, the bis- pin ends of T3- circulating connection T4-, E1- high
Kill-job mouth, E2- pit shaft protective device, E3- seal assembly, E4- casing hanger, E5- low pressure well head.
Specific embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
The suspension arrangement as shown, a kind of drilling rod of the invention is met an urgent need, including the suspension of quick tieback sub T1, preventer connect
Head T2, circulating connection T3 and double pin end T4, the quick tieback sub T1 are connected to the preventer suspension joint T2's
Upper end, the circulating connection T3 are connected to the lower end of the preventer suspension joint T2, and double pin end T4 are connected to described
The lower end of circulating connection T3, the when in use quick tieback sub T1, preventer suspension joint T2, circulating connection T3 and double
Pin end T4 is sequentially connected and is put into high-pressure well mouth E1 by drilling rod.
Pit shaft protective device E2 is set to the inside of high-pressure well mouth E1, is provided with below the pit shaft protective device E2
Casing hanger E4 is connect in the inside and being located at of the high-pressure well mouth E1 close to the pit shaft protective device E2 and described sleeve pipe extension E4
The region at position is provided with seal assembly E3.Low pressure well head E5 is provided on the outside of the high-pressure well mouth E1.
Eaves corresponding with pit shaft protective device E2 upper inner structure is provided on the lateral wall of the circulating connection T3,
The eaves rides on the pit shaft protective device E2.
The preventer suspension joint T2 includes cylinder neck 21, and shoulder 22, the cylinder neck are provided on the cylinder neck 21
