Therefore, this application is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features disclosed herein.

As shown in FIG. 1 and FIG. 4 , the embodiment of the present application provides a multi-phase fluid distribution and treatment device, including a mixing mechanism 10 , and the mixing mechanism 10 includes a first tank 13 , a second tank 14 , and a third tank The first tank 13 and the second tank 14 communicate with the third tank 15 respectively. The first tank 13 and the third tank 15 form the first processing mechanism 11 and the second tank 15. 14 and the third tank 15 form a second processing mechanism 12; the reversing mechanism 16 communicates the first processing mechanism 11 and the second processing mechanism 12, and the reversing mechanism 16 drives the first processing mechanism 11 and the second processing mechanism 12 in different densities The liquid mixture is reciprocated between the first processing mechanism 11 and the second processing mechanism 12, so that the liquid mixture is separated from the first processing mechanism 11 and the second processing mechanism 12 and discharges gases and/or liquids of different densities; Mechanism 20, the distribution mechanism 20 connects the first tank 13, the second tank 14 and the third tank 15 to distribute the Gases and/or liquids of different densities.

The multiphase flow distribution and processing device provided in the embodiments of the present application is suitable for conveying gas, or liquid, or liquid-solid, or a multiphase flow mixture containing both gas and liquid, or a multiphase flow containing solid, gaseous and liquid materials at the same time Mixtures or other fluid materials, unless otherwise specified below, are described by taking the multiphase flow mixture as a mixture containing both gas and liquid as an example.

The specific structures of the first tank 13 , the second tank 14 and the third tank 15 are not particularly limited, as long as they can be used to accommodate the multiphase flow mixture and facilitate the transportation of the multiphase flow mixture.

In some embodiments of the present application, specifically, the first tank body 13 and the second tank body 14 are respectively communicated with the third tank body 15 through the reversing mechanism 16 . The reversing mechanism 16 can drive the liquid mixture to flow in the mixing mechanism 10 and change the flow direction of the liquid mixture in the mixing mechanism 10 . The reversing mechanism 16 drives the liquid mixture to be output from the first tank 13 or the second tank 14 to the third tank 15 . When the third tank 15 is filled with the liquid mixture, it is returned to the first tank 13 or the second tank 14 through the reversing mechanism 16, so that the first tank 13 or the second tank 14 forms a vacuum suction chamber or is compressed and discharged cavity.

In the following, the first tank body 13 is used as a vacuum suction chamber, and the second tank body 14 is used as a compression discharge chamber as an example, and the description will be given in conjunction with the above-mentioned specific structures;

When the first tank 13 is a suction chamber, the liquid mixture in the first tank 13 is sucked out under the driving of the driving mechanism, and the liquid mixture enters the third tank 15 along the pipeline group of the reversing mechanism 16. When the liquid mixture is full After the third tank 15 , the high oil-water mixture separated from the third tank 15 by sedimentation is continuously extruded and discharged from the third tank 15 , and the extruded high oil-water mixture enters along the pipeline group of the reversing mechanism 16 . The second tank 14, under the action of the continuously entering high oil-water mixture, forms a positive pressure cavity, and the second tank 14 compresses and discharges the gas and/or liquid at the top thereof.

By arranging the third tank 15 in the multiphase flow distribution and treatment device, both the first tank 13 and the second tank 15 can accommodate the multiphase flow mixture during feeding, that is, the first treatment mechanism 11, which can effectively increase the multiphase flow. The feed amount of the phase flow mixing device; similarly, when the second tank 14 is discharging material, the third tank 15 has been discharging liquid to the second tank 14, and the liquid in the third tank 15 It can be discharged to the outside through the second tank 14, which can effectively increase the output of the multiphase flow mixing and conveying device. At the same time, the liquid mixture in the first tank 13 and the second tank 14 will both flow to the third tank 15 for water separation, which can further increase the efficiency of the multiphase flow mixing device for pumping oil and gas.

It can be understood that, in the case of pumping the same volume of crude oil mixture, the multiphase flow mixing and conveying device in the present application has fewer reversals than the multiphase flow mixing and conveying device in the prior art. , which effectively reduces the number of commutations and the damage to the equipment caused by the impact during the commutation operation, which is beneficial to prolong the service life of the equipment and improve the reliability of the equipment. At the same time, the multiphase flow distribution processing device reduces the number of reversals and also reduces the number of times of opening and closing the valves on the pipeline group, and reduces the influence of the valve opening and closing on the pumping efficiency of the multiphase flow mixture.

Specifically, the multiphase flow distribution and treatment device further includes an input pipeline group and an output pipeline group. The input pipeline group is connected with the first tank body 13 and the second tank body 14 respectively, the first tank body 13 and the second tank body 14 are respectively connected to the distribution mechanism 20 through the output pipeline group, and the third tank body 15 is connected through the water distribution pipeline. Distribution mechanism 20. Among them, the input pipeline group is provided with a control valve, which is used to control the opening and closing of the input pipeline group, thereby controlling the input of the crude oil mixture of the multiphase flow separation and processing device; the output pipeline group is provided with a control valve, which is used to control the output pipeline group. Open and close, and then control the output of gas and/or liquid of the multiphase flow split treatment device.

Wherein, distributing and processing the multiphase flow mixture also includes the steps of initial input, sedimentation separation, initial circulation, water separation, distribution of gas and/or liquid, reversing operation, and reciprocating circulation. The following is the specific implementation process of each step.

The initial input, the crude oil mixture is input to the first tank 13 and the second tank 14 through the input pipeline group. Preferably, the first tank body 13 and the second tank body 14 are filled with the crude oil mixture, so that the air volume in the first tank body 13 and the second tank body 14 can be minimized, and the air entering the reversing mechanism can also be reduced. 16 and the possibility of damage to it. In other embodiments of the present application, the input crude oil mixture may also partially fill the first tank 13 and the second tank 14, which is not limited herein. In other embodiments of the present application, the multiphase flow mixture initially input into the first tank and the second tank may also be water or other substances, which are not limited herein.

Sedimentation separation, in the process of inputting and filling the first tank 13 and the second tank 14 with the crude oil mixture, according to different densities, various substances in the crude oil mixture continue to settle in the first tank 13 and the second tank 14 Separate and preliminarily separate the gas located at the upper part of the first tank body 13 and the second tank body 14 and the liquid mixture located at the lower part of the first tank body 13 and the second tank body 14 . Among them, the liquid mixture is generally a mixture of oil and water. In other embodiments of the present application, the input crude oil mixture may also contain no gas, which is not limited herein. In other embodiments of the present application, the liquid mixture may be not limited to water or oil, which is not limited herein.

In the initial cycle, when the first tank 13 and the second tank 14 are filled with the crude oil mixture, the reversing mechanism 16 randomly selects the first tank 13 or the second tank 14 to suck out the liquid mixture. In the following, unless otherwise specified, the first tank 13 is used as an example for the first tank to be sucked out. The liquid mixture that has undergone preliminary sedimentation and separation in the first tank 13 is continuously sucked out to the third tank 15, and a negative pressure cavity is formed in the first tank 13, and the control valve of the first tank 13 is connected to the input pipeline group. Open, the first tank 13 continues to suck in the supplemental crude oil mixture at the same time.

To separate water, when the third tank 15 is continuously input with a liquid mixture, according to different densities, various substances in the liquid mixture continue to settle and separate in the third tank 15 according to the different densities, and are further separated into the third tank. The high oil-water mixture at the top of the tank 15 and the water at the bottom of the third tank 15. After the third tank 15 is filled with the liquid mixture, the high oil-water mixture at the top of the third tank 15 is returned to the second tank 14 through the reversing mechanism 16 under the pressure of the third tank 15 continuously inputting the liquid mixture. (i.e. the tank that has not been sucked out of the liquid mixture). Moreover, during the vacuum suction of the first tank 13 and the compression and discharge of the third tank 15, the second tank 14 also continues to perform sedimentation and separation at the same time, so the sedimentation and separation time in the second tank 14 is Compared with the first tank body 13 and the second tank body 14, it is longer, so the sedimentation and separation effect in the second tank body 14 is better.
