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 gas from a drilled core, and analyzing and storing the gas, said drilled core being obtained from seabed sediment, the apparatus comprising:

a needle (10) to be inserted into the drilled core (1) to allow the gas in the drilled core (1) to be discharged to the outside of the drilled core (1);

a first gas storing container (20);

gas analyzing parts (2a) and (2b);

a first 3-way valve (30) into which the gas passed through the needle (10) is introduced and which controls the introduced gas so as to be supplied to the gas storing container (20) or to the gas analyzing parts (2a) and (2b);

a gas analysis channel determining unit (60) which allows the gas passed through the first 3-way valve to be supplied to one of the gas analyzing parts (2a) or (2b);

a second gas storing container (70) for storing gas that does not move to the gas analyzing apparatuses by the gas analysis channel determining unit (60);

a second 3-way valve (50) positioned between the needle (10) for core insertion and the first 3-way valve (30) to allow 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; and

a connection pipe connecting the needle (10) for core insertion and the second 3-way valve (50) and made of a transparent material,

wherein the needle (10) is provided with a gas introduction hole (11) on the side of the needle, through which the gas in the drilled core (1) flows into the needle.

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, from the drilled core (1) to the first 3-way valve (30) through the needle (10), wherein the pressure controlling valve (40) is connected to the needle (10) and to the first 3-way valve.
