PRODUCTS DETAILS

Wholesale API oil tricone rock drill bits with metal face sealed bearing from China factory. Bit Description: IADC: 417-TCI journal sealed bearing bit with gauge protection for soft formations with low compressive strength and high drillability. Compressive Strength: 65-85 MPA 9,000-12,000 PSI Ground Description: Long intervals of very soft poorly compacted shales, dolomites, sandstones, clays, salts and limestones. We can offer TCI bits and steel teeth bits in a variety of sizes (from 3” to 26”) and most of IADC Codes. The world's major natural gas extraction countries are the United States, Russia, Turkmenistan, Iran, Qatar, Algeria, the Netherlands and so on. China has also started producing shale gas in recent years. One of the main use of the most do is the metal sealed bearing tricone bits. Natural gas, like oil, is buried in closed geological formations, some in the same layer as oil, some in isolation. Natural gas stored in the same zone as crude oil will be extracted along with it. Due to the complicated geological conditions of natural gas deep well drilling, the unforeseeable engineering geological problems lead to the difference between actual drilling and design and lead drilling to serious drilling complications and accidents, which not only endanger safety and the realization of geological objectives, but also seriously restrict the improvement of drilling speed and significantly increase drilling costs.

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 distancetrenchless 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.
