Abstract: The present disclosure discloses a method for detecting gas-storing performance of solution-mined salt cavern in a high-insoluble salt mine, comprising: detecting water-tightness of the cavern and water-tightness of a wellbore; arranging a gas sealing tubing in a production casing for the wellbore, and arranging a packer; detecting gas-tightness of the wellbore; injecting test gas into the cavern through the gas sealing tubing at a gas-injection well; calculating a volume of a discharged brine; closing the debrining well, and injecting the test gas into the cavern through the gas sealing tubing at the gas-injection well; after a pressure value above a gas-liquid interface in the cavern reaches a set pressure value, closing the gas-injection well; and detecting gas-tightness of the cavern. The method can be used for effectively, accurately and economically detecting the available gas storing space volume and the gas-tightness of the solution-mined salt cavern in salt mine.

Abstract: The disclosure provides a liquid taking device and a liquid taking method. The liquid taking device comprises a liquid taking bottle, a heavy ball and liquid taking ropes. The liquid taking bottle has a first mouth and a bottom opposite to the first mouth. The heavy ball is arranged in the liquid taking bottle. The liquid taking device can be controlled to reach different depths under the ground by the action of two liquid ropes. When the first mouth of the bottle is placed facing downward, the heavy ball blocks the first mouth of the bottle under its own gravity to prevent liquid leakage; when the first mouth of the bottle is turned upwards under the action of the liquid taking rope, the heavy ball falls onto the bottom of the bottle, such that an external liquid can flow into the liquid taking device, which has a good practical utility.
