Product Description Product DescriptionDrill collars are generally divided into three types: spiral drill collars, non-magnetic drill collars, and integral drill collars.(1) The overall drill collar is a smooth thick walled circular tube, with connecting threads machined at both ends.(2) Spiral drill collars are machined with three right-handed spiral grooves on the outer cylindrical surface of the circular drill collar to reduce the contact area with the wellbore wall and effectively prevent pressure difference from sticking the drill bit(3) Non magnetic drill collars are mainly used for monitoring during oil drilling, and their structure is the same as the overall drill collar. Non magnetic drill collars are made of N1310 low-carbon alloy steel, which is forged through strict chemical composition analysis. The material has undergone mechanical performance testing to ensure that its hardness, toughness, impact value, and corrosion resistance meet the standards, and it has good low magnetic permeability and good mechanical processing performance.For the convenience of drilling, elevator slots and slip slots can be machined on the outer surface of the internal thread of the drill collar.Executive standard: SY5144-2007.API7-1 Product Parameters SizeWeightOutsideWallDesignationDesignation lb/ftDiameterThickness ln.mmln.mm4 1/2"9.5~15.104.5114.30.205~0.3375.21~8.565"11.50~24.1051270.220~0.5005.59~12.705 1/2"14.00~43.105.5139.70.244~0.8756.20~22.236 5/8"20.00~32.006.625168.280.288~0.4757.32~12.067"17.00~57.107177.80.231~0.8755.87~22.237 5/8"24.00~55.307.625193.680.300~0.6877.62~19.057 3/4"46.18.625219.080.59515.118 5/8"24.00~49.008.625219.080.264~0.5576.71~14.159 5/8"32.30~75.609.625244.480.312~0.7977.92~20.2410 3/4"32.75~85.3010.75273.050.279~0.7977.09~20.2411 3/4"42.00~71.0011.75298.450.333~0.5828.46~14.7813 3/8"48.00~72.0013.375339.730.330~0.5148.38~13.06Manufacturing using AISI4145H chromium molybdenum alloy steel by rolling or forging, effectively controlling the chemical composition and trace element content.(1) Apply drilling pressure to the drill bit;(2) Ensure necessary strength under compression conditions;(3) Reduce the vibration, swinging, and jumping of the drill bit to ensure smooth operation of the drill bit;(4) Control well inclination.
