PRODUCTS DETAILS

Wholesale mining well tricone drilling bits with discounted price from China factory. Bit Description: IADC:732 - TCI standard open bearing roller bit for hard semi-abrasive and abrasive formations. Compressive Strength: 100-150 MPA 14,500-23,000 PSI Ground Description: Hard, well-compacted rocks such as :hard silica limestones,quarzite streaks,pyrite ores,hematite ores,magnetite ores,chromium ores,phosphorite ores,and granites. We can offer mining tricone rock drill bits in a variety of sizes and most of IADC Codes.In coal mine drilling, complicated geological and hydrologic conditions, thick alluvium of topsoil, many quicksand layers, large water inflow, large well diameter, deep wellbore, and often concentrated operation scale, as well as high temperature, high pressure and high formation stress in the deep well, will greatly aggravate the severity of underground complexity and the difficulty of treatment. Some problems should be solved according to the characteristics of coal mine drilling: 1.The problem of increasing drilling speed. 2.Prevention and treatment of well collapse, diameter reduction, drilling drop and other accidents. 3.Anti-deviation technology. 4.High temperature resistance。 5.Problems of cutting tools in deep well construction. The production system of Mining Industry is a complex system composed of many links. Therefore, it is necessary to perfect the structure of the large-diameter bit.With the increase of drilling fluid density and well depth, the fluid column pressure exerts a pressure holding effect on the broken cuttings at the bottom of the well, and the broken cuttings from the cone bit are not easy to leave the bottom of the well under the action of differential pressure, resulting in the formation of a cushion at the bottom of the well, reducing the crushing efficiency, etc. Reasonable bit structure will speed up the flow of cuttings in the bottom hole, improve the crushing efficiency, accelerate the drilling speed and shorten the drilling cycle. As well as improving the life of the roller bit, the service life of the roller has a great impact on the construction cost of drilling well. The life of the roller bit mainly depends on the life of seal, bearing and parent. Choose the proper rocks drilling bits is very important before starting project. Rocks hardness could be soft , medium and hard or very hard, hardness of one type of rocks may be also a little different, for example, limestone, sandstone shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone , etc. In drilling project, Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including coal mine drilling,copper mining,iron ore,gold ore and so on.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque.
