Hematite Powder is a mineral, coloured black to steel. It is mined as a main of iron ore and used as a weighting agent in oil drilling. It is the mineral form of iron(III) oxide (Fe2O3). Fluids weighted with API Hematite Powder contain fewer solids by volume than, making higher mud fluids possible. API Grade Hematite Powder is applicable in all types of drilling fluids, including freshwater, seawater and oil-base muds. It is used as a density increasing product, used as a weighting agent and in the paint industry. Hematite is also a harder mineral than Barite so it is more resistant to particle size degradation.

4145h api 7-1 drill collars are made of modified aisi 4145h chromium molybdenum alloy steel. These drill collar bars are full-length heat treated and water quenched to obtain astm a-370 mechanical properties. Full mechanical and chemical mill test certifications are supplied with all drill collars. These mill test certifications guarantee a hardness range of 285 to 341 bhn and an impact value of 40 ft.-lbs. At room temperature one inch below the surface. To ensure close tolerance bores, all drill collar bars are trepanned then drifted to api specifications. Bar surface finish is “as rolled” which is original mill finish. Connections: All connections are precision-machined to api specifications. Api relief groove pin and bore back box stress relief are available on request. Thread roots are cold-worked to offer a greater resistance to fatigue. All connections are phosphated to minimize galling during makeup and applied with thread storage compound. Thread protectors are installed to ensure adequate joint protection during shipment.

China supplier high quality LAKE Square drive Roller Kelly bushing consists of lower body half, upper body half, roller, roller pin and etc. when the bushing is installed to square kelly or hex kelly, the square part of the lower body half can be fitted in the square of the master bushing. When operating, the rotary table drive master bushing and master bushing drive Roller Kelly bushing and Roller Kelly bushing drive square kelly or hex Kelly to rotate, such is the torque transporting. The lower body half is conically shaped to readily enter the bore of the master bushing and automatically center bushing and drill string within the bore of the master bushing. Inside rollers are journal bearings which are fitted to the roller pin, when kelly rotates and moves downward, the rollers rotates with Kelly, such change sliding friction to rolling friction and minimize the abrasion of the kelly. The bushing is equipped with mud-scrapper assembly to clean the mud. The Square Drive Roller Kelly Bushing provides the following advantages: 1.Pulling out or feeding off string can be done while rotating; 2.Because of its integral construction, it can not fly out and hurts you. 3.The bushing is easily installed into the master bushing, maintaining good alignment; 4.The contact between Kelly and roller is rolling contact, so friction is lower, and weight on bit is accurate; 5.The Kelly has lower wear and has long life.

1.Description: The mechanical-hydraulic drilling jar is a jarring and stuck releasing tool. It integrates the up jar and down jar and can release the stuck accident occurring during drilling operation. The drilling jar is an ideal tool for directional well and deep well drilling. Operating principle 1.Operating principle of up jar Lifting drilling tool, slip assembly which bear the acting of dish reed elastic force and slip locking force compels latch mechanism of slip clasp slip mandrel. While slip mandrel up run with mandrel to overcome slip locking force and damping action between hydraulic valve assembly and spindle extension, jar Make drill stem accumulate energy, delay time. When mandrel up run to the state of release constraint, elastic potential energy accumulated in drill stem will convert to upward kinetic energy, generate up jar. If need sequence up jar, you need fed off drilling tool till relock latch mechanism, reduplication above process, Generate sequence up jar. 2.Operating principle of down jar The loosen load of down jar lock can be transfer as per in demand .There are a certain ratio between up locking force and down locking force , and the ratio is adjustable. If down jar, fed off drilling tool until pressure reach to down locking force, jar should generate down jar force. If need to repeat jar, lifting drilling tool to anew securing position repeat above process.
