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.
How to deal with quicksand formation?
In case of quicksand formation, the viscosity of drilling fluid must be increased and the bentonite content in the drilling fluid must be increased. Generally, it is required to be greater than 10%. A single seal is added to enhance the wall building property of the drilling fluid. In engineering, by appropriately reducing the displacement and reducing the erosion of convective sand layer, the well section must be closed with thick mud with viscosity greater than 80s before tripping out, so as to ensure the smooth running of drilling equipment and electric logging casing
