| Summary: | The article analyses various types of well-kill fluids that can be used when carrying out repair work of gas and gas condensate wells with high formation temperatures. Killing fluids based on the emulsion or polymer solution (without solid phase) are determined to have a number of disadvantages which significantly limit their use in such conditions. The possibility and perspectives of using the compounds with a condensed solid phase as killing luids under high formation temperatures are theoretically proved. The article also notes that the solution formed in the solid phase is supposed to treat as acid chemical compounds and provide the possibility of complete removal of its particles from the bottomhole formation zone during acidic treatments. |
