PRODUCTS DETAILS

Wholesale API natural gas tricone rock drill bits with metal face sealed bearing from China factory. Bit Description: IADC: 517-TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength. Compressive Strength: 85-100 MPA 12,000-14,500 PSI Ground Description: Medium hard and abrasive rocks such as sandstones with streaks of quartz, hard limestone or chert, hematite ores, hard, well-compacted abrasive rock such as: sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse grained rocks. We can offer tricone bits in a variety of sizes (from 3” to 26”) and most of IADC Codes. As a geophysical logging channel, it can obtain various geophysical data of underground rock and mineral layers. As an artificial channel, it can observe the underground geological conditions and the underground fluid dynamics. Using wellbore to exploit underground oil, natural gas, groundwater, geothermal resources. The technique used in drilling boreholes for oil and gas exploration and development. It mainly includes well design, selection of drill bit and mud, combination of drilling tools, coordination of drilling parameters, deviation control, mud treatment, coring, accident prevention, and treatment, etc. The characteristics of oil drilling technology are a deep hole, high pressure, high temperature, and many influencing factors. According to the geological and geographical conditions and engineering needs of oil and gas exploration and development, there are two types of vertical Wells and directional Wells. The latter can be divided into general directional Wells, horizontal Wells, and cluster Wells.

9 1/2 inches rock drill bits IADC437 is for soft formations well drilling. Choose the proper rocks drilling bits is very important before starting project. For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distance trenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits. 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 oil field,natural gas,geological exploration,driectional boring,water well drilling ,The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of tricone 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. It is also hlep us to find the siutable drill bits after you can tell us vertical well drilling or horizontal drilling ,oil well drilling or No-Digdrilling or foundation piling.
