Product Application

 

It is mainly used for geological general investigation and exploration, road and tall buliding foundation exploration, kinds of hole in concrete structure, river levees,earth temperature central air-conditioner,etc

It is mainly used for general survey and exploration of solid deposits, engineering geological exploration and other drilling holes, and inspection holes of various concrete structures.Diamond, alloy and steel bit can be selected for drilling according to different formations

 

Drilling method of pebble layer

 

1 conventional drilling methods and characteristics

At present, conventional drilling methods such as diamond drilling, clean water flushing, pipe reaming and mud circulation are generally used, while rotary drilling, dry drilling, pipe following, percussion, steel wire drill and other coring methods are used for core mining.

The disadvantages of these methods in drilling pebble layer are large drilling load, many accidents in the hole, low drilling efficiency and poor coring quality.

2. Drilling method and characteristics of diamond drilling tool combined with vegetable glue washing fluid

In order to meet the requirements of drilling in various hard and fragile formations, a series of single acting double barrel diamond drilling tools combined with vegetable gum washing fluid have been specially developed. It is also a relatively advanced method of drilling progressive cores in such formations at present. This method is a drilling process using vegetable gum as washing fluid and diamond as drilling tool.

The main characteristics of this process are small rotary resistance, high drilling efficiency, good coring quality, and strong ability to discharge sand and carry rock powder.
