DRILLING ASSEMBLY FOR GROUND COMPACTION IN WELL Russian patent published in 2005 - IPC

Abstract RU 2255183 C1

FIELD: building equipment, particularly adapted for drilling vertical, horizontal and inclined wells along with well side compaction.

SUBSTANCE: drilling assembly includes executive device with hollow body. Hollow body is made as upper and lower truncated cones connected one to another by major cone bases. Hollow drill-rod made as a pipe rigidly connected by one end with base mechanism is arranged inside executive device. Rock cutting mechanism is secured to another drill-rod end. Inlet and outlet orifices connected one to another through pipes are formed in executive device body.

EFFECT: reduced energy inputs for well drilling and well side compaction.
