Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Firstly, the design purpose of the present invention is described: the present invention is designed to realize the function of stabilizing the production fluid flow in the process of mechanical oil recovery in oil fields. Its purpose is mainly as follows: firstly, this type of float-type current stabilizer can stabilize the flow of unsteady production fluid; secondly, this type of float-type current stabilizer can provide a stable working environment for the downhole oil-water separation system, Guarantee the working efficiency of the downhole separator; finally, this type of float type current stabilizer can rely on the rotating structure to achieve the steady flow effect, has self-recovery function and quick interface, and can be easily applied to different pipe sections of the downhole pipe string.

[0016] Set forth below the specific composition of the scheme o...

Abstract

The invention provides a float-type flow stabilizer, and mainly aims at solving the problem that in the prior art, a relevant device which can be installed inside an oil field shaft to achieve a flow stabilization effect does not exist. The float-type flow stabilizer is characterized by further comprising an inlet spiral diversion structural body, a flow stabilization float, an anti-blocking inverted cone and an outlet spiral diversion structural body. A plurality of diversion holes and a tapered cavity are formed in the flow stabilization float. The inlet spiral diversion structural body and the outlet spiral diversion structural body are connected with a cylindrical cavity of a central pipe through threads. A righting rod and the anti-blocking inverted cone are fixedly connected between the inlet spiral diversion structural body and the outlet spiral diversion structural body in sequence. The flow stabilization float sleeves the outside of the righting rod and can slide vertically along the righting rod. A spring is fixed on the right rod in a winding mode between the upper end of the flow stabilization float and the bottom of the inlet spiral diversion structural body. The tapered cavity and the anti-blocking inverted cone are mutually matched. The float-type flow stabilizer can slow down or avoid influence, caused by fluctuation of liquid flow parameters, on separation effect of a cyclone separator, thereby ensuring stable and efficiency operation of the cyclone separator.

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...
