Test depth
7.51~12.37 m	13.87	16.43	1.184092	2.554655
8.98~9.03 m	2.112	50.36	23.83333	48.224
9.96~10 m	282.74	320.32	1.132898	37.576
10.94~11 m	97.5	109.64	1.124549	12.144
12.4~14.43 m	0.069	0.192	2.753813	0.1218578

Note: 7.51~12.37 m is 3# pore single embolic pressurization test result; 8.98~9.03 m, 9.96~10 m, and 10.94~11 m are 3# pore double embolic pressurization test result; and 12.4~14.43 m is 4# pore single embolic pressurization test result.
