n: The jet stream flows along bottom due to resistance of bottom in jet drilling. It is favour of cleaning cuttings.

flow between formations via a connected wellbore. Crossflow, as seen by downhole cameras, can occur with the wellbore full of fluid and the appearance of a dead well at surface.

n: refer to flame jet drilling

n: the minimum hydro-power which is needed to make the bottom of the well clean and clear in jet drilling

n: refer toflame jet drilling

n: the rig has additional fuctions on the base of nomal rig :transporting fuel and fire retardant to the bottom ,bleeding off the waste gas to surface and airing,what is more ,the rig is equipped with flame jet tools for experiment

n: a kind of drilling process in which use the high-temperature and high-speed frame blewout from the fuel to break the rock

n: a drilling technics that can progress the speed of drilling, which by using muzzles high pressure jet to clear hole bottom, to reduce to cut reaptely fracture and to cut by hydraulic force.

n: The working regime that determining all hydraulic parameters according to maximum bit hydraulic horsepower in jet drilling .

n: The working regime that determining all hydraulic parameters according to maximum jet impact force in jet drilling .

n: The working regime that determining hydraulic parameters and delivery capacity
according to maximum jet velocity in jet drilling .
