Description

Technical Field

[0001] The utility model relates to the technical field of petroleum fracturing engineering, in particular to a liquid discharge device for petroleum fracturing engineering. Background Art

[0002] In the field of petroleum, fracturing refers to a method of using hydraulic force to form cracks in oil and gas layers during oil or gas production, also known as hydraulic fracturing. In oil fracturing projects, the liquid generated during construction needs to be discharged through drainage equipment. Since the construction point and the drainage point are not in the same location, they need to be connected and drained through pipelines. For long-distance transportation, one pipeline cannot meet the drainage needs, so the pipelines need to be connected;

[0003] For example, the Chinese utility model provides a "liquid discharge device for oil fracturing engineering" patent number: CN217634247U, the liquid discharge device for oil fracturing engineering comprises: a first liquid discharge pipe and a second liquid discharge pipe docked with each other for discharge; a lifting device, the lifting device is arranged below the docking point of the first liquid discharge pipe and the second liquid discharge pipe, the lifting device comprises a lifting frame, the top of the lifting frame is provided with a first arc groove for supporting the first liquid discharge pipe, the top of the lifting frame is provided with a second arc groove for supporting the second liquid discharge pipe, the liquid discharge device for oil fracturing engineering provided by the utility model can raise the height of the first liquid discharge pipe and the second liquid discharge pipe through the lifting device arranged at the docking point of the first liquid discharge pipe and the second liquid discharge pipe, so as to facilitate the inspection and maintenance of the bottom of the pipeline, and when the first liquid discharge pipe and the second liquid discharge pipe are docked and leakage occurs, the liquid finally enters the recovery frame for recovery;

[0004] Although the above document can raise the height of the first drain pipe and the second drain pipe by providing a lifting device at the joint of the first drain pipe and the second drain pipe, so as to facilitate the inspection and maintenance of the bottom of the pipeline, and when leakage occurs between the first drain pipe and the second drain pipe, the liquid finally enters the recovery frame for recovery, but it does not have a shielding and protective function, resulting in the connection being easily cracked due to staff walking and trampling, as well as falling objects during use, which affects the efficiency of drainage and brings trouble to the staff. For this reason, we propose a drainage device for oil fracturing engineering to solve the above problems. Utility Model Content
