| Abstract: | According to the drilling in complex formations and based on the principle of wire-line drilling, the study on new methods for casing drilling for geological exploration are made by using coring drilling with retractable bit without lifting, including casing coring tools, casing replacing wire-line coring tube, wall protection and casing drilling processing. Good technical and economic effects are achieved in the field production test, and further improving suggestions are put forward according to the existing problems. |
