Abstract

Provided is an apparatus for extracting, analyzing, and storing gas in a drilled core on a ship. The apparatus includes: a needle for core insertion inserted into the drilled core to allow the gas in the drilled core to the outside; and a first 3-way valve into which the gas passing through the needle for core insertion is introduced and which controls the introduced gas so as to be supplied to a gas storing container or gas analyzing apparatuses positioned on a ship

Claims

1. An apparatus for extracting, analyzing, and storing gas in a drilled core secured through ocean exploration on a ship by supplying the gas to gas analyzing apparatuses 2a and 2b, the apparatus comprising:

the needle 10 for core insertion inserted into the drilled core 1 to allow the gas in the drilled core 1 to be discharged to the outside; and

the first 3-way valve 30 into which the gas passing through the needle 10 for core insertion is introduced and which controls the introduced gas so as to be supplied to a gas storing container 20 or gas analyzing apparatuses 2a and 2b positioned on a ship.

2. The apparatus of claim 1, further comprising a pressure controlling valve 40 allowing the gas to be discharged at pressure in a predetermined range when the gas is discharged to the first 3-way valve 30 through the needle 10 for core insertion.

3. The apparatus of claim 1, wherein a gas introduction hole 11 formed so that the gas in the drilled core 1 is introduced thereinto in order to be discharged to the outside is formed at a side of the needle 10 for core insertion.

4. The apparatus of claim 1, further comprising the second 3-way valve 50 allowing the gas passing through the needle 10 for core insertion to be supplied to the first 3-way valve 30 or to be discharged to the outside.

5. The apparatus of claim 1, further comprising an analysis channel determining unit 60 allowing the gas passing through the first 3-way valve 30 to be supplied to a predetermined gas analyzing apparatus 2a or 2b among a plurality of gas analyzing apparatuses 2a and 2b.

6. The apparatus of claim 2, wherein a gas introduction hole 11 formed so that the gas in the drilled core 1 is introduced thereinto in order to be discharged to the outside is formed at a side of the needle 10 for core insertion.

7. The apparatus of claim 2, further comprising the second 3-way valve 50 allowing the gas passing through the needle 10 for core insertion to be supplied to the first 3-way valve 30 or to be discharged to the outside.

8. The apparatus of claim 2, further comprising an analysis channel determining unit 60 allowing the gas passing through the first 3-way valve 30 to be supplied to a predetermined gas analyzing apparatus 2a or 2b among a plurality of gas analyzing apparatuses 2a and 2b.
