Description

Technical Field

[0001] The utility model relates to the technical field of on-site gas sampling, in particular to a gas-liquid separator for on-site gas sampling at a well site. Background Art

[0002] During the production process of oil and gas fields, as the exploitation proceeds, it is necessary to regularly perform phase analysis on the produced fluids of the oil wells to detect the chemical composition of the oil phase, water phase and gas phase, so as to provide a basis for the subsequent adjustment of the production plan and the implementation of anti-corrosion and anti-scaling measures. When sampling, general equipment generally collects oil and gas at the same time, rather than collecting them separately. The sampling steps for a single form are more cumbersome, while it becomes much simpler to perform classified sampling between oil and gas. In addition, when sampling gas, the excessive pressure of the rushing gas can easily cause danger to the sampling tank.

[0003] In the existing patent technology CN212317982U, a safe sampling device for oil and gas wellheads is recorded, which includes a placing trolley, a mounting frame is welded on the placing trolley, an oil sampling tank and an oil and gas sampling tank are vertically mounted on the mounting frame, a buffer tank is connected between the oil sampling tank and the oil and gas sampling tank through a gas pipeline, and a pressure reducing layer for multi-layer step-by-step buffering of oil and gas is arranged in the buffer tank. The utility model is provided with an oil sampling tank and an oil and gas sampling tank, and the liquid and gas of oil production are sampled separately. The sampled specimen enters the oil sampling tank, and the gas is separated from the oil and liquid and passed into the buffer tank and collected in the oil and gas sampling tank. The buffer tank is provided with a pressure reducing layer for multi-layer step-by-step buffering of oil and gas. The pressure reduction of the pressure reducing layer in the buffer tank makes the pressure of the oil and gas introduced into the oil and gas sampling tank controllably buffered, so that sampling is safer.
