Abstract

The invention discloses a device of fracturing fluid flowback equipment and a technological process of the device and relates to the field of oil filed wastewater treatment. The device comprises an oil field sewage tank, a micro-floating separation tank, a middle water tank, a first filtering device and a second filtering device, wherein the first filtering device comprises a first-level filter tank and a buffer tank; the second filtering device comprises a second-level filter tank and an RO (reverse osmosis) treatment device; a micro-floating filter net is arranged at a water outlet of the micro-floating separation tank; a middle filter net is arranged at a water outlet of the middle water tank; a chemical addition device is arranged on the micro-floating separation tank; a stirring device is arranged in the middle water tank; a grid and a first filter net are sequentially arranged in the first-level filter tank from top to bottom; a second filter net is arranged in the second-level filter net; a reverse cleaning device is arranged between the first-level filter tank and the buffer tank. The device is convenient to operate, and the adopted technological process is reliable during operation; by comparison with a traditional process, more than 60% of electricity is saved, the floor area is saved by more than 50%, the oil field wastewater is treated completely and becomes clean, and the quality of effluent water is stable and meets requirements.

Description

technical field [0001] The invention relates to the field of oilfield sewage treatment, in particular to a device for fracturing flowback fluid equipment and a process flow thereof. Background technique [0002] As the main means of increasing production of conventional and unconventional oil and gas resources, fracturing construction operations have a very complex fracturing fluid system, which consists of: polymers, bactericides, clay stabilizers, buffers, surfactants, alkalis, delay additives, High-temperature stabilizers, iron inhibitors, cross-linking agents, cross-linking stabilizers / activators, gel breakers, etc., so that the composition of the fracturing flowback fluid produced in the later stage of fracturing construction is extremely complex, and its water quality is mainly manifested as The following characteristics: high COD, high TDS, high suspended solids, and the water quality fluctuates greatly. If the fracturing fluid returned to the ground is discharged wi...
