Description

technical field [0001] The invention belongs to the technical field of petroleum exploration and development, and in particular relates to a device for cutting rock samples. Background technique [0002] With the further development of unconventional oil and gas resources, accurate acquisition of reservoir geological data is of great significance to the effective and safe development of drilling and development projects. The stratum can be described by conducting indoor experiments on cores taken from underground formations. Usually, full-scale cores obtained on site cannot be directly used in laboratory experiments, and further processing and cutting are required to take out small core columns that meet the experimental requirements before the rock mechanics laboratory can be carried out. experiment. At present, there are mainly mechanical drill type and wire cutting type for core extraction, but the mechanical vibration is large during the processing, which greatly distur...
