[0001] The utility model belongs to the technical field of petroleum production, and in particular relates to ultra-high pressure sample separation and sampling equipment. Background Art

[0002] Ultra-high pressure separation technology is a technology that separates oil under extremely high pressure conditions. This technology can efficiently separate different components in oil, such as crude oil, associated gas, and produced water, to meet the needs of oil production and processing. In practical applications, ultra-high pressure separation technology is often combined with other separation technologies, such as gravity separation, centrifugal separation, and flotation separation.

[0003] Ultrahigh-pressure separators are used to separate petroleum mixtures under ultrahigh pressure conditions to obtain components such as crude oil, associated gas, and produced water. Ultrahigh-pressure sample separation and sampling equipment for petroleum is an indispensable tool in the exploration, development, and production of petroleum. This type of equipment is typically used to extract petroleum samples from high-pressure environments and ensure the integrity and representativeness of the samples for subsequent analysis and testing. Common oil extraction equipment extracts the oil, transfers it to the laboratory, separates it, and then analyzes and tests the oil content. However, this method requires transferring the oil to different equipment, resulting in reduced detection efficiency. Utility Model Content

However, this method requires the oil to be transferred to different equipment, resulting in reduced detection efficiency.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an ultrahigh-pressure sample separation and sampling device, comprising a body and a control panel mounted on the surface of the body, an air compressor mounted inside the body, a side panel connected to the back of the body, a sample tube connected to one side of the side panel, and an electric vibrator mounted inside the body;

In addition, the sampling bottle is connected to the sample outlet through a transparent hose, and the sample outlet switch is turned on. If the pressure inside the sample tube is low, compressed air needs to be added from the tail end of the sample tube through an air compressor to press the crude oil sample out of the sample tube. When liquid sample appears in the transparent hose at the end of the sample outlet, the sample outlet switch is closed, and the gas sample transfer is completed. Thereafter, the same operation is performed to transfer the crude oil liquid from the sample outlet, making it convenient to separate and sample the crude oil liquid simultaneously, thereby improving the efficiency of subsequent oil analysis and detection.
