Description

technical field [0001] The invention relates to the technical field of high-efficiency rock breaking in oil and gas drilling, in particular to the new technology field of laser-mechanical rock breaking. Background technique [0002] The key to increasing the speed of oil and gas development is to increase the drilling speed, and the key to increasing the drilling speed is efficient rock breaking technology and equipment. At present, the main battlefield of my country's oil and gas exploration and development has gradually shifted to deep, ultra-deep, complex and difficult-to-drill formations and unconventional formations, and the difficulty of drilling has increased sharply. , low rock breaking efficiency, slow drilling speed, and high cost have become one of the main bottlenecks restricting the efficient exploration and development of oil and gas resources in my country. Therefore, there is an urgent need for new high-efficiency rock-breaking drilling technology and equipme...

Problems solved by technology

[0003] At present, in response to the low drilling efficiency in deep, ultra-deep and complex formations that are difficult to drill, many new rock-breaking technologies have been proposed at home and abroad, such as shock-absorbing rock-breaking, thermal jet rock-breaking, ultrasonic rock-breaking and other technologies, but These technologies cannot be widely used due to problems such as narrow scope of application and low efficiency. Laser-mechanical rock breaking is a brand-new drilling concept. , greatly reducing rock strength and improving rock drillability, thereby providing favorable conditions for subsequent mechanical rotary drilling. Laser-mechanical rock breaking technology can greatly improve the efficiency of mechanical rock breaking, with a wide range of applications and high efficiency

[0004] Emphasizing the research on the basic scientific theory of laser-mechanical rock breaking is of great significance to the development of my country's drilling engineering discipline. Today's laser-mechanical rock breaking technology is still in the experimental research stage. A fully functional and well-designed test device is important for The role of the research on this technology is undoubtedly very huge, so in order to conduct in-depth theoretical and experimental research on this technology, the present invention designs a laser-mechanical rock breaking test device
