The pipeline flow deflector type oil-water separator comprises a liquid inlet pipe segment, a gradually-expanding pipe segment, a rotational flow generating pipe segment and a water removing pipe segment which are connected in sequence, wherein the rotational flow generating pipe segment comprises a rotational flow pipeline and more than two flow deflectors which are fixedly and obliquely arranged in the rotational flow pipeline; when an oil-water mixed liquid flows through the flow deflectors, a centrally-symmetrical rotational-flow field is formed, so that oil and water are separated centrifugally; the water removing pipe segment comprises a water removing pipeline; the water removing pipeline is provided with an oil inlet and an oil outlet; and the oil removing pipeline is provided with over one group of water removing holes along the axial direction of the pipe. Due to the adoption of the oil-water separator, the symmetric stability of the rotational flow field can be improved, an oil-water separating technology is improved, the utilization ratio of an underground oil-water separator space is increased, and a good industrial application prospect is achieved.
