The huge geothermal energy contained in hot dry rock of the earth’s crust has become the research focuses for new energy development worldwide. At present, in the key technology of thermal recovery, or the formation of a heat exchange system in impermeable hot dry rock body, there are three modes, namely engineered artificial fracture system, natural fracture system and natural fracture-fault system. Hydraulic fracturing is a commonly used method for artificial thermal reservoir construction. Research in this area in our country is still in an experimental simulation stage. We completed one hot dry rock exploration hole (GRY1 hole) and 2 groups of hydraulic fracturing test and achieved good results in Chenzhuang town of Lijin County in 2014.This paper gives a brief introduction to the results of the project and aims to provide certain reference for future research on artificial heat reservoir construction technology.
