Leakage-proof device for drilling pipeline and leakage-proof method thereof

Abstract

The invention discloses a leakage-proof device for a drilling pipeline and a leakage-proof method thereof. The device comprises a first bottom plate and two pipe bodies, four first threaded rods are symmetrically and fixedly connected to the upper surface of the first bottom plate, and first sleeves are in threaded connection with the outer side walls of the four first threaded rods correspondingly; and second sleeves are rotatably connected to one ends of the four first sleeves through bearings. During use, when the drilling pipeline is installed in a butt joint manner, connection is more accurate, meanwhile, an eighth fixing plate slides in a sliding groove through a sliding block, a mother buckle and a son buckle are connected in a clamped manner, a second spring is extruded by the mother buckle, and the position of the sliding block is limited. The positions of two pipe bodies are fixed, so that the sealing performance of the drilling pipeline is higher, petroleum leakage is prevented when the drilling pipeline is used, drilling pipelines with different calibers can be adjusted, installed and fixed, the adaptability is high, the application range is wide, operation is easy, theinstallation speed is high, meanwhile, dismounting is convenient, and follow-up maintenance of the pipe bodies is facilitated.

Description

technical field [0001] The invention relates to the technical field of leakage prevention of drilling pipelines, in particular to a leakage prevention device for drilling pipelines and a leakage prevention method thereof. Background technique [0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons in natural occurrence. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products, such as solutions, fertilizers, pesticides and plastics. During oil drilling, drilling pipes are needed to transport oil. In the process of oil transportation, avoiding oil leakage at the joints of pipelines is an important research topic in the process of oil production and processing. [0003] Existing patent (CN211398869U) discloses a pipeline leak-proof structure of an assembled building pipeline system, which realizes the clamping of the upper and lower sides of the building pipeline by rotating the screw rod. The ...

Problems solved by technology

The anti-leakage device for drilling pipelines in the existing patents lacks a support structure for the drilling pipelines during use. Because the weight of the drilling pipelines is usually heavy, the drilling pipelines are easy to tilt during the process of docking the drilling pipelines, and the drilling pipelines There is a butt joint gap at the butt joint, and the leak-proof effect is poor; the butt-fixing operation of the pipeline is complicated, which is inconvenient for the staff to install and disassemble the pipeline, and causes inconvenience to the later maintenance of the pipeline; the leak-proof device is heavy and inconvenient to move
