Mixture of a radioactive tracer substance and a propellent for marking drilling tools for deep wells and similar boreholes |
| abstract |
For the expulsion of radioactive indicators from tracer cavities in drilling tools for deep wells and similar boreholes propellants are used which do not react with the water of the circulating drilling fluid in stoichiometric proportions. The propellents consist of a mixture of aluminum powder and an alkali metal peroxide as the primer and an explosive as the gas-yielding component. Ammonium picrate may be used with special advantage as the gas-yielding component. |
