| Abstract:In view of hard rock drilling difficulties in fracture zones during ocean drilling， and with the summary of the main technical difficulties and solutions in drilling of the fracture zone formation at home and abroad， this paper analyzes the characteristics of the fracture zone formation often encountered in the construction with regard to field cases， and proposes a new idea of applying chemical gel technology to solve complicated problems in fractured zone formation. The basic formulation of the chemical gel system suitable for different formation temperatures has been developed. Through orthogonal experimental design， a complete operation procedure for high temperature resin gel wall protection has been formed for deep-sea drilling. |
