| Abstract: | Tangshan Caofeidao hotel is located in the Quaternary strata area along the coastal region. According to the drilling technical difficulties of deep geothermal well in Quaternary hole shrinkage soft layer, low fluid loss and high density sodium soil slurry and pump capacity control were adopted for wall protection drilling in the design and construction. The paper summed up the drilling and completion technologies of a deep geothermal well in hole shrinkage soft layer. |
