Abstract

The invention relates to a fracturing flow-back fluid separation device, in particular to a fracturing flow-back fluid separation device for oil exploitation, the device comprises a mounting frame, a water inlet pipe, a filter frame, a stirring assembly, a gel breaking assembly and the like, a water inlet pipe is arranged on the mounting frame, the water inlet pipe is communicated with the mounting frame, a filtering frame is fixedly mounted on the mounting frame, the stirring assembly is arranged on the mounting frame, and the gel breaking assembly is arranged on the stirring assembly. The gel breaking agent in the hollow stirring frame is sprayed into the fracturing flow-back fluid from the spraying opening, the gel breaking agent removes the gel of the fracturing flow-back fluid, meanwhile, the hollow stirring frame stirs and cooperates with the fracturing flow-back fluid in the hollow stirring frame, the gel breaking agent and the fracturing flow-back fluid are fully mixed, and the gel breaking agent can fully remove the gel of the fracturing flow-back fluid.

Description

technical field [0001] The invention relates to a separation device for fracturing flowback liquid, in particular to a separation device for fracturing flowback liquid used in oil development. Background technique [0002] In the process of oilfield development, a large amount of oil production sewage will inevitably be produced, and with the continuous extension of oil production time, the produced water will continue to rise, and the amount of sewage treatment will increase rapidly, which will bring huge pressure to environmental protection. After the fracturing construction is completed , the fracturing flowback fluid contains a large amount of guar gum, formaldehyde, petroleum and other additives. At present, the three-stage treatment process of sedimentation-coagulation-filtration is often used to pretreat the fracturing flowback fluid, and then Perform fine filtration to meet reinjection standards. [0003] In the pretreatment process, rapid gel breaking is the key to...
