7. method according to claim 4, it is characterised in that the gas that compacting air inlet is passed through in step (1)
Pressure is 0.01-0.1MPa.
8. method according to claim 4, it is characterised in that the gas is incombustible gas；
Preferably, the gas includes nitrogen or air.
9. method according to claim 4, it is characterised in that gradually increase described in step (2) gas pressure include with
Lower step：
Since gas pressure is for 0.1-1.0MPa, 0.1-1.0MPa was increased per 1-3 hours, and compaction pressure is no more than 10MPa.
10. method according to claim 4, it is characterised in that the gas that gas drive air inlet is passed through in step (3)
Pressure is 0.01-0.5MPa.
11. methods according to claim 4, it is characterised in that the increasing degree of gas drive pressure is not more than in step (3)
0.5MPa, and the breakthrough pressure is not more than the compaction pressure.
12. methods according to claim 4, it is characterised in that water, specific behaviour are collected using graduated cylinder in step (2)-(3)
Make as follows：Flexible pipe is connected in water outlet gas outlet, and the flexible pipe is put into graduated cylinder to collect water；
Preferably, the graduated cylinder is the graduated cylinder for containing a certain amount of water.
