Problems solved by technology
[0003] The sealing of the wellhead is very important in the process of oil and gas production. It is mainly for the purpose of preventing sand and water at the wellhead. In the existing technology, most of the oil and gas collection pipelines are threaded or welded with the wellhead. It is very inconvenient for maintenance and cleaning. Therefore, we propose a quick sealing device for oil and gas production wellheads.

The invention discloses an oil and gas exploitation wellhead rapid sealing device which comprises a fixing assembly, a sealing assembly and a sealing assembly. The fixing assembly is installed under the ground of an oil wellhead, and the installation end of the fixing assembly extends to the ground; the sealing installation assembly is installed in the fixing assembly, the sealing installation assembly is inserted into the fixing assembly in a sliding mode, and the sealing installation assembly and the fixing assembly are locked and fixed through a fixing threaded pin. Through the split design of the fixing assembly and the sealing installation assembly, the fixing assembly and the sealing installation assembly can be rapidly separated while sealing is conducted, and maintenance and cleaning of the oil and gas collecting pipeline are facilitated; through the arrangement of the annular sealing air bag, the annular sealing air bag can be tightly attached to the surface of the oil gas collecting pipeline to achieve sealing, and the mode is used in cooperation with the arc-shaped clamping plates, and the certain oil gas collecting pipeline fixing effect is achieved.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a quick sealing device for oil and gas exploitation wellheads. Background technique [0002] Oil and gas extraction is the process of extracting oil and natural gas buried in underground oil layers from the ground. The way that oil and gas is extracted from the underground to the surface can be divided into: self-injection and artificial lift according to whether it is necessary to artificially supplement the energy of the wellbore fluid. Artificial lift oil production includes: gas lift oil production, pumping unit rod pump oil production, submersible electric centrifugal pump oil production, hydraulic piston pump oil production and jet pump oil production. [0003] In the process of oil and gas exploitation, the sealing of the wellhead is very important, which is mainly for the wellhead sand control and waterproofing. In the prior art, most of the oil and gas ...
