A wellbore surrounding rock creep support structure

Abstract

The application provides a wellbore surrounding rock creep supporting structure, and belongs to the technical field of supporting structures. The wellbore surrounding rock creep supporting structure comprises a supporting assembly, the supporting assembly comprises a first box-shaped steel pipe, a second box-shaped steel pipe, a third box-shaped steel pipe, a first anchor cable and a second anchor cable, the first box-shaped steel pipe, the second box-shaped steel pipe and the third box-shaped steel pipe are symmetrically arranged, and the first anchor cable and the second anchor cable are respectively arranged on one side of the first box-shaped steel pipe, the second box-shaped steel pipe and the third box-shaped steel pipe at intervals and are fixed by bolts. In the whole use process, the concrete well ring supporting strength is high, the wellbore deformation can be effectively controlled, the wellbore deformation and rock falling can be avoided to avoid hurting people or damaging equipment and facilities, the maintenance section is relatively small, the well ring sinking caused by the fact that the wellbore wall is completely broken can be effectively prevented, and convenient installation and disassembly can improve the maintenance efficiency.
