Abstract:

Combining the project practice, the paper introduced the application of new through-type self-developed hydraulic pipe cutter in the treatment of embedment accident of deep hole casing and wireline drilling rod. Such tool overcomes some disadvantages of the traditional hydraulic pipe cutter; and moreover, it has advantages of simple operation, high controllability and short pipe cutting time, and further, it is capable of effectively improving the treatment efficiency of deep hole embedment accident.

Key words:through-type; hydraulic pipe cutter; deep hole drilling; wireline coring; pipe cutting time
