Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0050] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention belongs to the technical field of sewage treatment and relates to a fracturing flow-back fluid treatment system and technology. Fracturing flow-back fluid conveyed by a lifting pump andozone generated by an ozone generation device are mixed through an ozone jet flow adding device to form a gas-liquid mixed solution; the gas-liquid mixed solution is conveyed into a catalytic reactiontank and is subjected to catalytic oxidization reaction under pressure, so that the reaction speed is greatly improved. First treatment fluid treated by the catalytic reaction tank enters a first airfloating tank and dross is floated by utilizing gas remained in water under the cooperative effect of a cyclone state. Second treatment fluid treated by the first air floating tank enters a cyclone gas-dissolving air floating device and dross is further removed. Third treatment liquid treated by the cyclone gas-dissolving air floating device enters a filter and is filtered; if returning utilization is met, recycling can be directly realized. The fracturing flow-back fluid treatment system and technology integrate an ozone oxidization reaction device and the cyclone gas-dissolving air floatingdevice and gel breaking and viscosity breaking can be rapidly realized; the oxidization efficiency and the ozone utilization rate are improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a fracturing flowback fluid treatment system and process. Background technique [0002] Fracturing flowback fluid is a mixed fluid that is flowed back to the ground after fracturing the formation using hydraulic fracturing technology to increase the production of oil and gas wells. It not only includes the fracturing fluid originally injected into the formation, but also carries a variety of pollutants. After years of development, hydraulic fracturing technology has become one of the important stimulation measures to improve the productivity of oil and gas wells and the recovery of oil reservoirs. The fracturing fluid has high viscosity, low fluid loss, and good rheology, so as to realize the purpose of fracturing fluid to transmit pressure and purify fractures. In order to meet the performance requirements of the above fracturing fluid, it is necessary...
