Successful Drilling Practice of Crawler Deep Well Drilling Rig in Sudan's Hot and Arid Areas

In the extremely arid environment of North Darfur, Sudan, a high-performance crawler water well drilling rig FY300 successfully completed a livelihood water well project with a depth of 180 meters and a diameter of 325 mm. Faced with a surface temperature of 52°C and complex basalt formations, the equipment demonstrated excellent high temperature adaptability and hard rock drilling capabilities, providing a continuous and stable source of drinking water for the local community.

Difficulties of this work

1.Extreme climate

Summer temperature in the operation area exceeds 50℃, and the hydraulic system of conventional equipment is prone to overheating and shutdown

Sandstorms occur frequently, and key components require special dust protection

2.Complex geology

0-80 meters of overburden: loose gravel is prone to collapse

Below 80 meters: Class VII basalt layer (Mohs hardness 7.2)

3.Transportation restrictions

Road conditions in remote areas are poor, and equipment needs to be modularly disassembled and transported

Customer value

People's livelihood security

The daily water output of a single well is 500m³, meeting the daily water demand of 5,000 people

The water quality TDS value is reduced to 186mg/L (raw water source>2000mg/L)

Economic verification

Comprehensive fuel consumption is reduced by 38%

The spare parts commonality rate is 85%, and the local maintenance cost is reduced by 60%
