Description

Technical Field

[0001] This utility model relates to the field of fracturing flowback fluid technology, specifically a device for collecting and reusing fracturing flowback fluid from oil and gas field drilling. Background Technology

[0002] Fracturing flowback fluid is a liquid produced during oil and gas field development, especially in hydraulic fracturing operations. With the widespread application of fracturing technology in unconventional oil and gas field development, its production has increased accordingly. This fluid is characterized by high COD content, high mineralization, and high suspended solids. Its composition is complex, and it may contain substances harmful to the environment. Improper handling can lead to water pollution, soil salinization, and other problems.

[0003] Traditionally, fracturing flowback fluid collection and treatment relies on a single filtration system, which results in incomplete filtration and increases the burden on the filter, requiring frequent cleaning or replacement of the filter element. This leads to low collection and treatment efficiency and affects usability. Utility Model Content

Then, a pipe end is fixedly connected to one end of the feed pipe, allowing fracturing flowback fluid to be injected into the settling tank. After a period of settling and sedimentation inside the settling tank, the control panel controls the extraction pump to draw the liquid from the top and inject it into the filter tank through a connecting pipe. As the liquid flows through the filter tank, multiple inner filter plates filter and adsorb the liquid.
