Rotary flow stabilizer

Abstract

A rotary flow stabilizer mainly solves the problem that no relevant device for achieving the effect of flow stabilizing and installed in an oil field shaft exists in the prior art. The rotary flow stabilizer is characterized in that the upper end and the lower end of a central tube are an upper connector and a lower connector of an oil tube of a conical main body. The rotary flow stabilizer further comprises a disk support and a spiral blade, wherein flow guiding holes are respectively arranged in a front support single body and a rear support signal body of the disk support, and a central rod penetrates through a central through hole of the front support single body to be limited and fixed at the central portion of the rear support single body. A torsion spring is sleeved outside the central rod, the upper end of the torsion spring is connected with the spiral blade to serve as a free end capable of rotating along with the spiral blade, and the lower end of the torsion spring is connected with the disk support to serve as the fixed end. The flow stabilizer is applicable to the underground working conditions, can reduce or avoid the influence on the separating effect of a rotary flow separator caused by liquid flow parameter fluctuation and ensures the stable and efficient operation.

Description

technical field [0001] The invention relates to a flow stabilizing and flow control device used in the oilfield wellbore in the field of petroleum exploitation. Background technique [0002] At present, the method of realizing pre-separation of produced fluid in the wellbore in the process of oil field mechanical oil recovery mainly adopts downhole separation and same well reinjection system. The system adopts downhole pumping method combined with separation technology to first separate the produced fluid inside the wellbore, and then pump the oil-rich phase and water-rich phase to the surface or suitable formations respectively. The cyclone separator has become the most commonly used downhole separator because of its small size and high efficiency. Cyclone separation mainly relies on the centrifugal force formed by the rotating flow to achieve separation, so it is greatly affected by the stability of incoming liquid flow. Especially in the case of a sharp increase in the...
