Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 As shown, the preferred embodiment of the fracturing flowback fluid integrated treatment system of the present invention mainly includes a gas-solid comprehensive treatment module A; a liquid phase recovery module B; a treatment pool module C; an oxidation treatment module D;
[0037] The high-pressure fracturing flowback fluid sprayed from the wellhead passes through the pressure-resistant manifold and the liquid inlet of the pressure reducing valve, and the high-pressure fracturing flowback fluid is converted into atmospheric pressure fracturing flowback fluid, and then enters the gas-solid comprehensive treatment module A. In the gas-solid comprehensive treatment module A, the gas-liquid-solid three-phase separation of the normal pressure fracturing flowback fluid is carried out, the separated gas phase and ...

The invention provides a fracturing flow-back liquid modularization integrated treatment system which comprises a gas-solid phase comprehensive treatment module, a liquid-phase recycling module, a treatment pond module, an oxidation treatment module and a filtration circulation module, wherein the gas-solid phase comprehensive treatment module is used for performing recycling and combustion treatment on the gas phase and used for performing recycling and collection treatment on the solid phase; the five modules are respectively used or used together according to operation demands of practical fields. The invention fundamentally aims to perform concentrated high-efficiency treatment on fracturing flow-back liquids. By adopting the fracturing flow-back liquid modularization integrated treatment system, on-site direct treatment on the fracturing flowback liquid is implemented, and a final product can be directly combusted, discharged or reused, so that both the transportation and treatment expenses are reduced, and the utilization rate of the water resource is increased, and the treatment process has relatively wide application prospect on an oil field fracturing site as environment protection is advocated by all the people at present.
Description
technical field [0001] The invention relates to the technical field of on-site fracturing flowback fluid treatment equipment in oilfields, and in particular, the invention particularly relates to a modular integrated treatment system for fracturing flowback fluid. Background technique [0002] As the main means of increasing production of conventional and unconventional oil and gas resources, fracturing operation is very complex, and contains various chemical components such as thickeners and crosslinking agents, such as polymers, organic substances, inorganic substances, etc. There are so many types and complex components that the components of the fracturing residual fluid produced at the end of the fracturing operation are extremely complex, which manifests as: gas, liquid, oil, and solid multi-phase existence, and the liquid phase is characterized by high COD, high TDS, High suspended solids, large fluctuations in water quality; it is a type of oilfield wastewater that i...
