Embodiment

[0036] The invention provides a treatment system for fracturing flowback fluid, such as figure 1 As shown, the treatment system includes a flowback liquid reaction device, a first screw pump 6, a filter press 7, a solid phase collection tank 8, a filtrate fine filtration device, a third screw pump 12, a filter membrane assembly 13 and a water storage tank 14 . The flowback liquid reaction device is used to separate out the impurities in the flowback liquid in the form of solid precipitation, which includes a submersible sewage pump 1, a reaction tank 2 connected to the submersible sewage pump 1, and a A mixer 3 , a dosing tank 4 connected to the reaction tank 2 , and a control cabinet 5 respectively connected to the agitator 3 and the dosing tank 4 ; the reaction tank 2 is connected to a first screw pump 6 .

[0037] The filter press 7 is used to separate the solid-liquid from the flowback liquid after the solid impurities have been precipitated. As a preference, in this embo...

Abstract

The invention discloses a fracturing flow-back fluid treatment system and a treatment technology and aims to solve the problems that the existing fracturing flow-back fluid treatment technology pollutes the environment, waste the resources and is high in fracturing construction cost. The fracturing flow-back fluid treatment system comprises a flow-back fluid reaction device, a first screw pump, a press filter, a filtrate fine filter, a third screw pump, a filter membrane assembly and a water storage tank, which are sequentially connected, and a solid phase collecting tank connected with the press filter. The fracturing flow-back fluid treatment system is reasonable in structure, simple in process and convenient to operate, and can greatly reduce environment pollution, improve the recycling utilization value of fracturing flow-back fluid and reduce treatment cost and later fracturing construction cost, thereby having high application value.

Description

technical field [0001] The invention relates to a process for treating fracturing flowback liquid. Background technique [0002] With the development of fracturing fluid, the requirements of low damage and low cost of fracturing fluid are becoming more and more prominent. At the same time, with the increase of large-scale fracturing, oil and gas recovery measures are more and more widely used in oil and gas fields, especially in the exploitation of shale gas and coalbed methane. The fracturing fluid has increased from tens or hundreds of square meters to tens of thousands On the other hand, there is rapid development from single fracturing to multiple fracturing, so the amount of waste fluid returned after fracturing has also increased significantly. [0003] The waste fluid after fracturing mainly includes slick water stock solution and flowback fluid, as well as polymers, salts, suspended solids, heavy metal ions and other additives. If the fracturing flowback fluid is d...
