Problems solved by technology

The existing sealer needs to stop the well for replacement when replacing the packing, which reduces the production efficiency of the oil well, and frequently shuts down the oil well to replace the packing of the sealer, which is likely to cause accidents in the well, and the labor intensity of the workers is high

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0015] According to attached Figure 1-3 As shown, the wellhead sealer for pumping wells includes a main body, and the lower part of the main body has a packing reinforcement part 5. The inner diameter of the packing reinforcement part 5 is smaller than the inner diameter of the main body. The position of the solid part of the root; the upper end of the main body is provided with a packing conveyor 1, and the packing conveyor 1 includes a tur...

Abstract

The invention relates to an improvement of a wellhead sealer structure, in particular to a pumping well wellhead sealer. The pumping well wellhead sealer comprises a body, a packing compacting part isarranged on the lower portion of the body, the inner diameter of the packing compacting part is smaller than the inner diameter of the body, a packing conveyor is arranged at the upper end of the body, and the packing conveyor comprises a rotary table rotatably connected with an upper end opening of the body. A pushing block is arranged at the lower end of the rotary table, the lower surface of the pushing block is obliquely arranged, the pushing block is arranged in the body, and a packing lifting-assisting device is arranged on the side of the middle portion of the body. The pumping well wellhead sealer does not need to stop the production of an oil well when replacing the packing, the packing conveyor only needs to be rotated, and the pushing block of the packing conveyor can push thepacking down round by round, the oil well does not need to be stopped, packing can be increased, the sealing effect is achieved, and a non-stop well method can greatly improve oil production efficiency.

Description

technical field [0001] The invention relates to an improvement of the structure of a well head sealer. Background technique [0002] In current oil extraction, the oil pumping polished rod reciprocates up and down in the oil pumping wellhead, and the sealing problem between the two is mainly realized by a sealer with packing inside. The existing sealer needs to stop the well for replacement when replacing the packing, which reduces the production efficiency of the oil well, and frequently shuts down the oil well to replace the packing of the sealer, which is likely to cause a well lying accident, and the labor intensity of the workers is high. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wellhead sealer for pumping wells that does not need to shut down the oil well when adding packing. [0004] The present invention is accomplished by adopting the following techn...
