  • Patent number: 12153031
    Abstract: A detection device includes a chamber, a top of the chamber is cover with a chamber cover, and a side wall of the chamber is provided with a port D5. The chamber is provided with a first waterproof layer and a second waterproof layer, and a water storage layer is disposed between the first waterproof layer and the second waterproof layer. A water supply pipe is disposed in the water storage layer, and the water supply pipe includes a port D2 and a port D7. An end second pipe is connected to the port D2, and another end of the second pipe facing away from the first pipe is provided with a port D3. An online detection component and a vacuum extraction system are disposed outside the chamber. The detection device can quantitatively simulate and detect the process of rare gas migration and accumulation under formation water conditions.

  • Patent number: 12085547
    Abstract: A buffer assembly for a noble gas isotope analysis device, including an air inlet pipe and an air-pressure buffer member. The air inlet pipe is connected to the noble gas isotope analysis device, and is provided with a valve. The air-pressure buffer member is provided in the air inlet pipe, and includes a connecting pipe arranged inside the air inlet pipe. Multiple pneumatic components are sleeved outside the connecting pipe, and are configured to be deformed under the action of a gas flow to decelerate the gas flow. A noble gas isotope analysis device including the buffer assembly and an isotope analysis method using the noble gas isotope analysis device are also provided.
