Description

Technical Field

[0001] The utility model relates to the field of oil and gas exploration drilling fluid services, in particular to a tank inner wall reciprocating steam cleaning device. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In current oil drilling fluid storage services, cleaning drilling fluid storage tanks remains a technical challenge. Due to the material properties of drilling fluid, its components tend to adhere to the tank walls and bottom, forming a hard layer of sediment. This sediment is not only difficult to remove through conventional agitation and circulation, but also becomes harder and more stubborn over time, making it extremely difficult to remove.

[0004] Currently, cleaning drilling fluid storage tanks is primarily a manual process. Workers are required to wear fully enclosed protective suits and descend into the tanks to perform the cleaning. Because drilling fluid contains a variety of chemicals that can be harmful to the environment and human health, proper worker protection is crucial. However, this method is not only labor-intensive but also presents numerous safety hazards. For example, the narrow working space inside the tanks makes accidents like slips and suffocation more likely. Furthermore, prolonged exposure to hazardous substances can also have long-term health consequences for workers.

[0005] Furthermore, existing cleaning methods typically require large amounts of water. This not only increases operating costs but also, in the current era of increasingly scarce water resources, makes this wasteful cleaning method increasingly unpopular. More importantly, the extensive use of water for flushing can cause harmful substances in the drilling fluid to be washed into the surrounding environment, causing secondary pollution. This pollution not only damages soil structure and affects plant growth, but can also seep into groundwater, causing long-term pollution of water resources.

[0006] In short, cleaning drilling fluid tanks presents a multifaceted challenge involving environmental protection, safety, and efficiency. With technological advancements and growing environmental awareness, more efficient and environmentally friendly solutions are poised to improve this situation. Utility Model Content
