Description

Technical Field

[0001] The utility model relates to the technical field of steam dryness sampling devices, in particular to a steam dryness sampler. Background Art

[0002] Steam dryness is the mass percentage of dry saturated steam contained in each kilogram of wet steam. If the water vapor contains 10% by mass of water, the steam has a dryness of 90%. During oil exploration and production, it is necessary to conduct surveys and monitoring of oil wells and obtain the steam dryness value at the downhole sampling point to accurately determine the location of the oil layer. Currently, when sampling, the steam dryness sampler directly pumps the steam from underground into the chamber, and then the staff detects the steam in the chamber. However, the steam obtained by the existing steam dryness sampler cannot be transferred, resulting in its inability to be transferred to other places for detection. When transferring the steam collected in the chamber to other containers, it is inevitable to come into contact with the outside world, and the original state of the steam cannot be guaranteed. The change in the steam state will affect the final detection result. Therefore, it is necessary to propose a steam dryness sampler. Content of the Utility Model

[0019] Next, in combination with the drawings and specific embodiments, the present utility model will be further described.

[0020] Please combine Figures 1 to 4, the steam dryness sampler of this embodiment includes: a sampling cylinder 1 with a first connecting pipe 2, an air extraction pump 6 for extracting underground steam is arranged on the sampling cylinder 1, a second connecting pipe 4 for connecting the air extraction pump 6 is arranged on the sampling cylinder 1, and a liftable piston 18 is arranged in the sampling cylinder 1;

[0021] A sealed cylinder 10 with a sealed cover 11, a third connecting pipe 8 connected to the sampling cylinder 1 is arranged on the sealed cylinder 10, a liftable motor 14 and a hexagonal nut 15 driven by the motor 14 are arranged in the sealed cylinder 10, a gas storage cylinder 16 for storing steam is arranged in the sealed cylinder 10, and a bottle cap 17 paired with the gas storage cylinder 16 is arranged in the hexagonal nut 15.

[0022] A first valve 3, a second valve 5, and a third valve 9 are respectively arranged on the first connecting pipe 2, the second connecting pipe 4, and the third connecting pipe 8.

[0023] Through the above technical solution, the first valve 3, the second valve 5, and the third valve 9 are respectively used to control the first connecting pipe 2, the second connecting pipe 4, and the third connecting pipe 8, so as to control the different states of the three connecting pipes at different stages, ensuring the smooth progress of the entire sampling and storage.

[0024] A fixed frame is arranged at the top of the sampling cylinder 1, a hydraulic push rod 7 is arranged in the fixed frame, and the piston 18 is fixedly connected to the output rod of the hydraulic push rod 7.

[0025] Through the above technical solution, the piston 18 can be pushed by the hydraulic push rod 7, so as to push the steam in the sampling cylinder 1 into the gas storage cylinder 16, thereby completing the transfer of the underground steam.

[0026] An electric push rod 12 is arranged in the sealed cylinder 10, a sleeve 13 for storing the motor 14 is arranged on the output rod of the electric push rod 12, the hexagonal nut 15 is at the top of the sleeve 13 and is rotatably connected to the sleeve 13, and the output shaft of the motor 14 is fixedly connected to the bottom of the hexagonal nut 15.

[0027] Through the above technical solution, the bottle cap 17 can be pushed and rotated, so that the bottle cap 17 can be tightened onto the bottle mouth of the gas storage cylinder 16, thereby sealing the gas storage cylinder 16, enabling the sampled underground steam to be transferred subsequently.

[0028] Threads are provided at the connection between the sealed cover 11 and the sealed cylinder 10, and the two are threadedly connected. A snap ring adapted to the gas storage cylinder 16 is arranged in the sealed cylinder 10, and anti-slip tooth grooves are arranged on the sealed cover 11.

[0029] Through the above technical solution, the gas storage cylinder 16 is adapted to the sealed cylinder 10. After the steam storage work is completed, the sealed cover 11 can be opened and the gas storage cylinder 16 can be taken out of the sealed cylinder 10.

[0030] One side of the sampling cylinder 1 is fixedly connected with a frame for supporting the third connecting pipe 8, and the third connecting pipe 8 is rotationally connected with the frame and the sampling cylinder 1.

[0031] Through the above technical solution, the frame can improve the stability of the third connecting pipe 8 while not affecting the rotation of the third connecting pipe 8, and the third connecting pipe 8 and the sampling cylinder 1 can rotate, which also enables the entire sealing cylinder 10 to rotate. Thus, after removing the sealing cover 11, the gas storage cylinder 16 can be directly poured out from the sealing cylinder 10, making it more convenient to take out the sealing cylinder 10.

[0032] The implementation principle of a steam dryness sampler in the embodiment of this application is as follows:

[0033] The first connecting pipe 2 is used to connect the sampling pipe leading to the ground. During sampling, the first valve 3 and the second valve 5 are opened, and the air extraction pump 6 is started to pump the underground steam into the sampling cylinder 1. Subsequently, the first valve 3 and the second valve 5 are closed and the third valve 9 is opened. At this time, the piston 18 is pushed by the hydraulic push rod 7 to push the steam in the sampling cylinder 1 into the gas storage cylinder 16 in the sealing cylinder 10 through the third connecting pipe 8. When the gas storage cylinder 16 is filled with steam, the electric push rod 12 and the motor 14 are started. The electric push rod 12 drives the motor 14, the hexagonal nut 15, and the bottle cap 17 to rise, and the motor 14 drives the hexagonal nut 15 and the bottle cap 17 to rotate until the bottle cap 17 is tightened onto the bottle mouth of the gas storage cylinder 16, thus completing the sealing of the sampled steam. Subsequently, the sealing cover 11 can be unscrewed to take out the gas storage cylinder 16, enabling the sampled steam to be transported to other places for testing.

[0034] The above implementation manner is only the preferred implementation manner of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the protection scope required by the present utility model.
