Product Feature

It is a portable hydraulic drill in China at present. It is especially suitable for coring operations in special difficult terrain such as mountains, hills and rivers, and for engineering geological survey of buildings such as railways, hydropower, transportation, bridges and dam foundations; Geological core drilling and physical survey; Drilling of small grouting holes and blasting holes; Small well drilling.

Main Application

This is a small portable geological exploration drilling rig developed by our factory.
1. The drilling rig is suitable for water well drilling, general survey exploration, geophysical exploration, road and building exploration, blasting hole drilling and other drilling projects.
2. Alloy, diamond and composite bits can be selected for drilling according to different bottom layers.
3. It can drill grade 2-9 sandy clay and rock stratum.

The main causes of drill pipe fracture

1, The bending moment of drill pipe is too large during reaming and pipeline pullback;

2, The causes of excessive bending moment are as follows: first, the actual curve of the guide hole deviates greatly from the theoretical curve; Second, the hole after reaming is irregular, which makes the pipe form an angle with the reamer and the drill pipe axis.

Other reasons:

1, In order to save investment, the directional drilling equipment used by the construction contractor (i.e. Party A) does not match the actual needs of the project construction. The tonnage of the directional drilling equipment is too small, the maintenance is not timely, and the failure rate is high, which makes the directional drilling force uneven. At the same time, the stop and go construction makes the hole forming quality poor, the hole irregular, the drilling tool is easy to lock, resulting in the fracture of the drill pipe;

2, The selection of reamer model is unreasonable. Failure to select the matching rule model according to the actual geological conditions, resulting in increased drilling torque, increased drill pipe wear and fracture;

3, When the rock reamer reams or cleans the hole, the drill pipe is not connected at the back, and the reamer swings greatly in the hole, which may cause the drill pipe and the main shaft of the reamer to break;
