abstract

  • Based on the formation characteristics of high temperature (above130°C ) and multi-salt, we optimize several blowing agent monomers to compound a new type of foaming agent, and screen out the new foam stabilizer to determine the new ebonite foam drilling fluid system. In the laboratory, we evaluated its resistance to high temperature, salt and oil pollution. And we made a research on its rheological characteristics of the foam and the behavior of high salinity. The experimental result shows that the ebonite foam drilling fluid has much more foam, longer stable time, significant effect of the resistance to high temperature, salt and oil pollution and has good sand-carrying ability, which can effectively prevent the occurrence of loss circulation and meet the requirement of rock carrying and wellbore stabilization.
