Abstract

The invention discloses an oilfield produced water treatment device, which comprises a dosing device, a cyclone separator, an air floatation device, a sintering pipe fine filter and an oil-water separation filter which are connected in turn; the oilfield produced water treatment device also comprises a gas source system which is connected with the sintering pipe fine filter and the oil-water separation filter. With skid-mounted design, all equipment and facilities are compactly arranged and fixed on a base, and thus are convenient to transport; moreover, quick connection and quick running as well as reutilization can be realized, and the cost is saved; the problems in produced water treatment emerging before station construction can be solved, or the oilfield produced water treatment device can replace a fixed station for performing an area produced water treatment task.

Description

technical field [0001] The invention belongs to the technical field of water treatment devices, and relates to a treatment device for oilfield produced water. Background technique [0002] With the continuous exploitation of oilfields, the water content of oilfield produced fluids increases year by year. At present, the average water content of Yanchang Oilfield and Daqing Oilfield has reached more than 90%, and the annual sewage production has reached about 30 million cubic meters and 400 million cubic meters respectively; the annual sewage production of Liaohe Oilfield has reached 38 million tons; the comprehensive water content of Shengli Oilfield has reached 90%~ 95%, the annual sewage production volume has reached 260 million cubic meters, and it has entered the stage of high water-cut oil production. Reinjection after treatment of oil production wastewater can not only reduce the serious environmental pollution caused by the discharge of oil production wastewater, gre...
