Torsional impact hammer is the key technology of fast drilling in deep and hard forma-tion.It is a new type of drilling tool collecting of mechanical shear,hydraulic and torsional impact. The study intended to introduce the current research and actual application of torsional impact hammer both at home and abroad,specifically expound its structure,characteristics and working principle,comparatively analysis the key technology of the torsional impact hammer’s advantages and disadvantages,point out that the localization of the hammer should focus on such aspects as reliable tool structure,working in high density drilling fluid,as well as a good application and prospect for development in the field of drilling.The study conclusion is certainly and referentially valuable for improvement and perfection of torsional impact hammer,realizing nationalization,the same too supporting the development and improvement of PDC bit.
