Problems solved by technology

[0005] Therefore, the above-mentioned transportation system is limited by the structure of the traditional mixing pump, and cannot realize the complete recovery of natural gas
In particular, the geological conditions of each oilfield are different, and the gas-liquid ratio is a variable, which makes the mixed transportation of oil and gas with complete gas recovery an extremely difficult problem

Embodiment

[0015] The rotor-type internal compression oil-gas mixed delivery pump unit of this embodiment is as follows: figure 1 , figure 2 As shown, the housing 1 is composed of a lower housing 1-1, an upper housing 1-2 and an upper housing cover 1-3, and the assembly is very convenient. The middle of which supports a pair of mutually meshing conjugate rotors 4 through bearings. The rotating shafts of the conjugate rotor 4 are in the same horizontal plane, and the cavity in the housing 1 is divided into a suction cavity 1-4 and a discharge cavity 1-5. Both sides of the suction chamber 1-4 are provided with fluid inlets 1-7, and both sides of the discharge chamber 1-5 are provided with fluid outlets 1-8. A partition wall 1-10 is provided between the conjugate rotor 4 and the fluid outlet 1-8 to separate the discharge chamber 1-5 into an engagement area 1-9 and a discharge area. The lower surface of the partition wall 1-10 is at a position tangent to the outer circle of the conjugate...

Abstract

The invention relates to a rotor-type internal-compression oil-gas mixed transport pump unit, and belongs to the technical field of fluid transportation devices. The unit comprises a housing which supports a pair of conjugated rotors engaged with each other; the cavity in the housing is partitioned by the conjugated rotors into an inhalation chamber and a discharging chamber; the inhalation chamber is equipped with a fluid inlet, and the discharging chamber is equipped with a fluid outlet; the discharging chamber is partitioned into an engaging area and a discharging area by an isolating wallwhich is disposed between the conjugated rotors and the fluid outlet; at least one one-way valve is disposed at the isolating wall; when the one-way valve is closed, the engaging chamber is completely isolated from the discharging chamber are; when the one-way valve is opened, the engaging chamber is communicated with the discharging chamber. Even in a multiphase medium transporting process with an unstable gas-liquid ratio, the rotor-type internal-compression oil-gas mixed transport pump unit of the invention has the unique function of internally compressing the gas medium, pressurizing the gas to a discharging pressure so as to discharge the gas out of the pump; the invention can completely eliminate the gas blocking phenomenon, and can reliably realize the internal-compression transporting process of the transported multiphase medium.

Description

technical field [0001] The invention relates to a delivery displacement pump for multi-phase medium, in particular to a rotor-type internal compression oil-gas mixed delivery pump unit, which belongs to the technical field of fluid delivery devices. Background technique [0002] In the process of oil production, the extracted crude oil often contains abundant oil-associated gas—natural gas. That is to say, the medium to be transported in oil extraction includes both liquid phase medium—crude oil, and gas phase medium—natural gas. The traditional transportation method is to separate the medium from gas to liquid first, and use a pump to transport the liquid phase medium, while the gas phase medium is transported by a compressor; or in the oil production block with unstable gas content, the traditional crude oil transportation process is The crude oil from each oil production well enters the buffer tank of the pressurization station through the manifold, and a small amount of...
