探査する。(Prior Art) Conventionally, natural gas exists as a water-soluble gas dissolved in water together with a mixture of various hydrocarbons. The unexplored gas-bearing layer where a viable amount of natural gas has accumulated is generally made of porous and highly permeable rock. If such natural gas exists, the formation layer can be investigated using geological methods (geological survey, paleontological survey), geophysical method (physical exploration), and geochemical method (geological method). explore.

This sampling method involves inserting an iron circular pipe into a sampling valve from the ground surface into a gas-bearing layer, and the gas layer generates energy that directs water-soluble gas from the gas-bearing layer into a steel circular pipe (sampling pipe). works, the water-soluble gas enters the sampling pipe, rises inside the pipe, and ejects to the ground surface, so-called self-ejection.The water-soluble gas ejected to the ground surface in this way is separated into gas and water, The gas is released upward and collected, and the water separated from the gas is discharged to the surface.

This is a diagram illustrating a method for automatically returning separated water to the underground, where E is the ground surface and 'M is the water-soluble water that exists at the depth of the ground surface. It is a labor layer that contains gas.

This gas sampling tube 1 is a double tube consisting of an outer tube 2 and an inner tube 3 housed therein.

この孔９から内管３へ侵入する。A large number of holes 5 are formed on the outer surface of the tip of the outer tube 2, and water-soluble gas enters the outer tube 2 through the holes 5. Further, the proximal end of the outer tube 2 near the ground surface E is wider than its distal end, forming a separation section 6 having a large cross-sectional area. A gas collection pipe 7 through which gas separated from water is released and collected is integrally formed above the separation part 6 of the outer tube 2. An inner tube 3 is housed within the outer tube 2, and a gas passage 4 is formed between the inner tube 3 and the outer tube 2 through which water-soluble gas rises. The base end 8 of the inner tube 3 is attached to a gas collection tube 7 that is integrally attached to the outer tube 2, and the inner tube 3 is suspended from the gas collection tube 7. Furthermore, a hole 9 is bored in the outer surface of the proximal end of the inner tube 3, and the water separated from the gas enters the inner tube 3 through this hole 9.

速が遅くなるので分離効果がよい。Next, a method of an embodiment of the above configuration will be explained. After a gas well is drilled, when the sampling pipe 1 is inserted into the gas-bearing layer M, energy is applied to push the water-soluble gas contained in the gas-bearing layer into the sampling pipe 1, and the water-soluble gas flows through the outer pipe. It enters through a hole 5 drilled in the outer surface of 2. In this case, the apparent specific gravity of the water-soluble gas contained in the gas-bearing layer M is approximately 0.
．． 4, the water-soluble gas that has entered the outer tube 2 rises in the gas passage 4 formed between the outer tube 2 and the inner tube 3 and is ejected to the ground surface. Water-soluble gas ejected to the earth's surface is automatically separated from water under atmospheric pressure. The separated gas is discharged upward and stored in the gas collection pipe 7. In this case, since the proximal end of the outer tube 2 forms the widened separation section 6, the cross-sectional area becomes large, and as a result, the flow rate of the water-soluble gas is slowed down, so that the separation effect is good.

The water flowing down the inner pipe 3 is forced into the gas-bearing layer M through the hole 5 of the outer pipe 2, and the water is automatically returned to the gas-bearing layer M.

利点がある。(Effects of the Present Invention) As explained above, according to the present invention, the gas sampling pipe is configured to have a double structure, and the water-soluble gas is allowed to rise inside the gas passage formed between the outer pipe and the inner pipe. The water-soluble gas ejected to the ground surface is separated into gas and water, the separated gas is released upwards, and the water is guided to the inner pipe and flows down inside the inner pipe to be returned to the ground1. As a result, there is no need to flow water separated from gas to the surface of the earth, which eliminates the problems of harmful substances such as organic salt compounds contained in water, which can cause problems to plant growth, and ground subsidence caused by pumping up water-soluble gases. This has the advantage of eliminating the risk of pollution problems occurring.
