Abstract

The invention relates to a combined drilling technique of vegetable gum diamond coring and downhole hammer casing drilling, which can be used for effectively solving the problem that the requirements of practical engineering exploration cannot be met due to difficulty in forming holes, low core recovery rate, low drilling efficiency and more hole accidents in a sandy cobble stratum. The technical scheme for solving the problem includes that the technique includes the steps: leveling land; positioning and mounting equipment; forming an excavation circulating system; drilling holes; performing vegetable gum diamond coring; recycling flushing fluid; performing downhole hammer casing drilling; and discharging residues, lifting a drill, replacing the drill for drilling and supplementing vegetable gum flushing fluid into the holes. The technique is simple and practical, effectively solves the problems of difficulty in forming the holes, low drilling efficiency, low core recovery rate and more hole accidents in the sandy cobble stratum, and is innovative in terms of drilling techniques.

Description

technical field [0001] The invention relates to a reconnaissance method, in particular to a combined drilling process of vegetable glue diamond coring and down-the-hole hammer and pipe. Background technique [0002] Sand and pebble formations are often encountered in the process of water conservancy and hydropower drilling. Drilling in sand and pebble formations will encounter difficulties in hole formation, low coring rate, low drilling efficiency and many holes. The existing sand and pebble formation drilling The drilling technology mainly includes steel grain drilling, diamond drilling and down-the-hole hammer drilling. The steel grain drilling process has low coring quality, casing follow-up is difficult, and there are many holes; the diamond drilling process has a high coring rate, However, the adaptability to the stratum is weak; although the down-the-hole hammer drilling process has strong stratum adaptability and high drilling efficiency, it does not take coring or t...
