| Abstract:Analysis was made on the mechanism of silicate polymer washing fluid system, a set of washing fluids especially for long borehole section with hidden downhole accidents in core drilling of sandstone uranium deposit. The practice shows that this washing fluid system can satisfy all requirements of wire-line coring drilling technologies and has good effects in dealing with complex sandstone formations. |
