Abstract
The invention provides a safe blowout prevention working barrel, and belongs to the technical field of preventing liquid from being sprayed in the oil pipe tripping work process. The safe blowout prevention working barrel aims to achieve the technical effect that the liquid in a pipe is prevented from being sprayed out in the tripping work process of the oil field work. According to the technical scheme, the safe blowout prevention working barrel is composed of a sealing segment, an upper connector, a main body and a lower connector; oil pipe threads are adopted for the two ends of the upper connector, the upper connector is connected with the main body through the oil pope threads in a sealed mode, two steps are arranged in the body, oil pipe threads are adopted for the two ends of the main body, and the main body is connected with the sealing segment through the oil pipe threads in a sealed mode. Oil pipe threads are adopted for the two ends of the sealing segment, and the sealing segment is connected with the lower connector through the oil pipe threads in a sealed mode. The safe blowout prevention working barrel has the advantages that by means of the safe blowout prevention working barrel, the liquid in a well can be prevented from being sprayed out effectively, the sealing function is achieved, and pollution to the environment and potential safety hazards are avoided.
Description
Technical field
When the invention belongs to the operation of oil pipe lift pipe string, prevent the technical field of hydrojet, i.e. safe blowout prevention seating nipple.
Background technology
At present, in the process of oil field operation lift pipe string operation, spray to prevent liquid in pipe, this instrument is arranged on the bottom of tubing string, when dropping into blanking plug, blanking plug therewith instrument cooperation is firmly linked with, thus tubing string is sealed, thus devise this safe blowout prevention seating nipple.
Summary of the invention
During in order to overcome lift pipe string operation, in well, liquid ejection, causes environment pollution and potential safety hazard.
The present invention solves the technical scheme that its technical problem takes: described safe blowout prevention seating nipple is made up of seal section, top connection, main body, lower contact; Top connection two ends adopt tubing round thread, and top connection is connected with bulk oil pipe thread seal, has two steps in main body, main body two ends adopt tubing round thread, main body and seal section tubing round thread are tightly connected, and seal section two ends adopt tubing round thread, and seal section and lower contact tubing round thread are tightly connected.
The invention has the beneficial effects as follows, this safe blowout prevention seating nipple effectively can prevent liquid ejection in well, achieves sealing function, avoids causing environment pollution and potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 seal section, 2 top connections, 3 main bodys, 4 lower contacts, 5 steps in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated: as shown in Figure 1, and described safe blowout prevention seating nipple is made up of seal section 1, top connection 2, main body 3, lower contact 4; Top connection 2 two ends adopt tubing round thread, top connection 2 and main body 3 tubing round thread are tightly connected, two steps 5 are had in main body 3, main body 3 two ends adopt tubing round thread, main body 3 and seal section 1 tubing round thread are tightly connected, seal section 1 two ends adopt tubing round thread, and seal section 1 and lower contact 4 tubing round thread are tightly connected.
After contacting with seal section 1 in blanking plug input oil pipe, in two limited blocks of blanking plug and cylinder, two steps 5 tangle respectively, seal section 1 seals and finally realizes seal fluid in cylinder and be sealed object, thus liquid ejection in effective prevention well, cause environment pollution and potential safety hazard, the unnecessary loss brought.This instrument is installed on bottom oil pipe when well pulling job by described safe blowout prevention seating nipple, being cast by blanking plug, coordinating be firmly linked with this seating nipple when playing oil pipe in oil pipe, realizes the function of sealing, and then realizes the function of blowout prevention.
