Description

Technical Field

[0001] The invention relates to the technical field of petroleum exploitation, in particular to a clean fracturing fluid emission control device. Background Art

[0002] With the large-scale development and utilization of unconventional oil and gas resources such as shale gas and tight oil, hydraulic fracturing technology has been widely used. This technology injects high-pressure fluid into underground rock formations to create cracks in the rock formations, thereby increasing the flow channels of oil and gas and improving the recovery rate. After the fracturing operation is completed, a large amount of return fluid needs to be effectively collected and processed, otherwise it will cause serious pollution to the environment.

[0003] In the prior art, when discharging fracturing fluid, the injection pipe needs to continuously adjust the injection direction to complete the injection of fracturing fluid at different depths, thereby obtaining a better fracturing effect. At the same time, during the injection of fracturing fluid, proppant also needs to be injected. Usually, the proppant is gravel. The proppant is used to support the cracks to facilitate subsequent related operations.

[0004] The gravels are of different sizes, and when passing through the nozzle of the injection tube, they may block the nozzle of the injection tube, thereby reducing the content of proppant entering the fracture, thereby affecting the support effect at the fracture. Summary of the invention
