Problems solved by technology

[0003] At present, the technical scheme of deep-sea oil exploitation is mainly: the gas-liquid mixture extracted from the seabed is transported to the offshore platform or oil and gas processing station through the lifting pump device, and then the gas-liquid separation is carried out. The disadvantages of this technical scheme are: (1) gas When the liquid is mixed and lifted, there will be a section of gas and a section of liquid in the pipeline, that is, slug flow. When slug flow occurs, the gas and liquid flow alternately in the pipeline, and the liquid plug that fills the entire pipeline area will be divided by the air mass. Below, flowing along the pipe is a layered liquid film
When slug flow occurs in the pipeline, the pressure of the pipeline and the instantaneous flow rate of gas and liquid will fluctuate greatly, which will cause a sharp increase in the pressure drop of the pipeline, which will have a great impact on the equipment and pipeline, and easily cause damage to the equipment and pipeline
(2) The lifting pump device is large in size, difficult to hoist and install on the seabed, expensive to install and maintain, and consumes a lot of power. It has high requirements for seabed transmission equipment and cables, and the investment cost is high

Abstract

The invention discloses a compact GLCC (Gas-Liquid Cylindrical Cyclone) separation supercharging device and a manufacturing method thereof. The compact GLCC separation supercharging device is characterized by comprising a GLCC separator which comprises an inclined cutting pipe and a vertical pipe; the upper end of the vertical pipe is provided with the gas outlet; the lower end of the vertical pipe is provided with the liquid outlet; the gas outlet is communicated with the upper portion of a supercharging buffer tank; the liquid outlet is communicated with the lower portion of the supercharging buffer tank; the opening formed at the upper end of the supercharging buffer tank is provided with a well head device; the lower end of the supercharging buffer tank is sealed; an electric submersible pump which is used for performing supercharging is arranged inside the supercharging buffer tank. The manufacturing method comprises performing analysis and calculation on the intensity of the external pressure through ANSYS software and performing integral manufacturing according to obtained drawings through the analysis. According to the compact GLCC separation supercharging device and the manufacturing method thereof, the gas-liquid separation is achieved at the bottom of the sea, the gas and the liquid after the separation are output to an offshore platform or an oil and gas treatment station, and accordingly the slug flow is not produced, the structure is simple and compact, the cost is low, a certain of external pressure resistance can be achieved due to the manufacturing method, and the work can be performed in the 2000 meter water depth of deep sea.
