Spiral Drill Collar - page 11 Non-Magnetic Drill Collar - page 10 Crossover Sub - page 16 Integral Blade Near Bit Stabilizer - page 4. 1 DRILLING TOOLS INTERNATIONAL: AN OVERVIEW Since 1984, Drilling Tools International, Inc. has been the leading provider of downhole drilling
A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater …
Spiral drill collar is our product line in one. Such drill collars in the drill collar round the outer cylindrical surface of the three right-handed helical groove machining a reduced area of contact with the wall and the rotation resistance, can effectively prevent differential sticking, the weight ratio of the spiral drill collars pass specification Model relieve ordinary drill collar ...
In drilling, a drill collar consists of a heavy pipe above the drill bit in a drill string. Uses for Shaft Collars. Shaft collars can be found in virtually any type of machinery and are frequently accessories to other components.
20-11-2020· Heavy Weight Drill Pipe in conjunction with undergauge stabilisers, should be used to substitute the drill collar weight. The clearance between drill collars and the wellbore is smaller than with DP, therefore increasing the possibility of differential sticking. If it is thought to be a potential problem, spiral drill collars can be used to ...
Spiral Design: In order to reduce differential pressure sticking and wellbore contact, the surface of Drill Collars can be spiral-grooved. Spiral Drill Collars are the perfect solution for deep, directional or deviated drilling. Cross sections of the drill collars reduce the contact area with the wall of the hole.
Drill collars. In drilling, a drill collar consists of a heavy pipe above the drill bit in a drill string. Uses for Shaft Collars. Shaft collars can be found in virtually any type of machinery and are frequently accessories to other components.
Drill collar is mainly used to provide bit weight to drill bit so that drill piipe is in tension. Especially drill collar can keep drill bit centralized and hole tradck by large rigidity. Spiral drill collar is used to reduce contact area with hole so as to avoid efficienty bit stricking from differential pressure.
Spiral Drill Collars The spiral cut is added to a drill collar to prevent the likelihood of differential wall-sticking by reducing wall contact between the drill collar and the wall of the hole. The spiralling starts 22" from the bottom of the slip recess or 79" from the box end and ends 30" from the pin end.

Spiral drill collaris one of the most important components of the drill string is to provide drilling bit of pressure and the drill string rigid role.Material :AISI 4145 H / 4145H Mod or Non-magnetic material.Types:Slick drill collars / Spiral drill
A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the drill bit.The term is loosely applied to the assembled collection of the drill pipe, drill collars, tools and drill bit.The drill string is hollow so that drilling fluid can be pumped down through it and circulated back up ...
