Problems solved by technology

The spoilers of the surface oil, gas and water three-phase flow mixing devices currently used all occupy the diameter of the oil, gas and water three-phase fluid flow pipeline, thereby reducing the flow space of oil, gas and water in the pipeline , resulting in an additional production pressure difference, which ultimately results in a decrease in oil and gas production

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the present invention includes an upper joint 1 for threaded connection with the oil pipeline, the other end of the upper joint 1 is threaded with a turbulence device 2, the other end of the turbulence device 2 is threaded with a lower joint 3, and the other end of the lower joint 3 is used for Connect the oil outlet pipe with thread.

[0015] Such as figure 1 , figure 2 As shown, the turbulence device 2 includes a number of disturbing flow sleeves 4 connected by threads, each of the turbulence sleeves 4 has the same structure, and a cylindrical central through hole is arranged in it, and the inner diameter of the central through hole is the same as that of the oil delivery pipe and the oil outlet pipe. The inner diameters are the same, and a first baffle disk 5 and a second baffle disk 6 are arranged at intervals...

Abstract

The invention relates to an oil, gas and water three-phase liquid mixing device which is characterized by comprising an upper joint, wherein the upper joint is connected with an oil transportation pipe, the other end of the upper joint is connected with a disturbing flow device, and the other end of the disturbing flow device is connected with a lower joint used for connecting an oil outlet pipe;the disturbing flow device comprises a plurality of disturbing flow sleeves in threaded connection, each distributing flow sleeve is internally provided with a cylindrical central through hole the inner diameter of which is same as the inner diameters of the oil transportation pipe and the oil outlet pipe, and two distributing flow plates are arranged in the central through hole at intervals; each distributing flow plate is of a circular ring shape and is provided with a plurality of distributing flow sheets at intervals along the circumferential direction. The oil, gas and water three-phase liquid mixing device is simple in structure, convenient to dismount and mount and good in oil, gas and water mixing effect and can be widely applied to the oil, gas and water three-phase liquid mixingprocess.

Description

technical field [0001] The invention relates to a mixing device, in particular to a downhole oil, gas and water three-phase flow mixing device for high production wells. Background technique [0002] At present, the oil, gas and water three-phase flow mixing devices used in oil fields at home and abroad are all used on the ground, and there is no oil, gas and water three-phase flow mixing device suitable for downhole. The spoilers of the surface oil, gas and water three-phase flow mixing devices currently used all occupy the diameter of the oil, gas and water three-phase fluid flow pipeline, thereby reducing the flow space of oil, gas and water in the pipeline , resulting in an additional production pressure difference, ultimately resulting in a reduction in oil and gas production. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an oil, gas and water three-phase flow mixing device capable of increasing oi...
