The wire line coring drilling is a geological exploration drilling construction method that an inner cylinder assembly of a drilling tool is put into a special wire line drill rod, and after the coring drilling is finished, the inner cylinder assembly is fished out by a wire line fisher to obtain a core on the ground, so that the working efficiency is greatly improved.

When the exploration, drilling and sampling are carried out, the hardness of a target stratum has softness or hardness, and when cores are taken for medium-hard or hard strata with uniform lithology and better columnarity, the cores are clamped and pulled off by a self-locking coring tool. The pressurized coring tool is selected to shear or twist off the core in loose, soft formations. However, in many cases, the unknown stratum with complicated soft and hard staggered change is faced, and in order to keep the integrity of soil information, a harder soil layer is usually selected for core cutting, so that on one hand, the harder stratum is difficult to position, on the other hand, the footage is limited, and the working efficiency is reduced.
