China's first geothermal scientific exploration well to reach 5,200 meters deep

China's first ultra-deep geothermal scientific exploration well, Fushenre-1, is anticipated to reach a subterranean depth of 5,200 meters on Monday, setting a new record for the deepest geothermal exploration well in the country. 

The well's drilling project is led by Sinopec, commenced in September last year in Haikou city of south China's island province Hainan. The exploration team took precautions against drilling pipe sticking and leakage while ensuring the drilling process was free from pollution like noise and rock debris.

Considering the high temperatures at the target layer and the strong abrasiveness of the geological strata, the well is posed with several challenges.
