Description

technical field [0001] The invention relates to a laser-assisted mechanical rock-breaking test device, which belongs to the fields of rock-breaking device technology, oil and gas resource drilling and exploitation, and the like. Background technique [0002] The underground reserves of oil and gas resources are very rich, which is an important source of energy to support the progress and development of human society. After a long period of exploitation, the oil and gas resources in shallow formations in some areas have been fully exploited. However, there are rich oil and gas resources under the high-hardness rocks in deep, ultra-deep and complex formations. With the deepening of oil and gas drilling depth, traditional mechanical drilling methods are facing low drilling efficiency in drilling high-hardness rocks. , long drilling cycle and high cost. [0003] As the country's demand for oil and gas resources continues to grow, the drilling task is getting heavier and heavie...
