Description

Technical Field

[0001] The utility model belongs to the technical field of plasma pulse unblocking and permeation-increasing devices for oil and gas deep wells, and more specifically, relates to a plasma pulse unblocking and permeation-increasing device for oil and gas deep wells. Background Art

[0002] The deep oil and gas well plasma pulse deblocking and permeability enhancement device is a technical equipment used in oil and gas well production. It is mainly used to solve the blockage problem that may occur in the oil and gas well production process and improve the permeability of the oil and gas well, thereby improving production efficiency. It uses plasma pulse technology to effectively remove blockages or sediments in the wellbore, while increasing permeability and restoring or improving the well's productivity.

[0003] Currently, when operating plasma pulse unblocking and permeation enhancement devices in some deep oil and gas wells, they are first connected to the pulse device with a cable, and then lowered into the deep well to carry out the unblocking and permeation enhancement work. After the operation is completed, the cable is reeled in by a reeling device and the pulse device is pulled out of the deep well. However, there is a large amount of mud and crude oil mixture in the deep well. This viscous mixture easily adheres to the surface of the cable. If it is not cleaned, the mixture will dry out after reeling, making it difficult to release the cable from the reeling device and greatly increasing the difficulty of subsequent cleaning.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a plasma pulse deblocking and permeation enhancement device for deep oil and gas wells is provided, in order to achieve a purpose with greater practical value. Utility Model Content
