Kompletní popis

Well drilling is an important process for extracting §oil, natural gas, water, and mineral materials. §Opening wells requires boring through earth §formations, which requires specialized tools and §operation procedures. Rotary drilling, in which a §drill bit is used to crush the rock and penetrate §into the formation, is one of the main methods of §well drilling. Rotary cone bits are one of the main §types of drill bits used for rotary drilling. There §are two main problems encountered when drilling with §rotary cone bits. Excessive vibration can cause §damage to the entire system and can decrease §efficiency of the drilling process. Failure of the §bit s bearings and seals can also result in damage §to the bit and cessation of the drilling process. In §this book, a new design for rotary cone bits, with §the objective of improving overall drilling §performance, is presented. First, a new pattern for §distribution of inserts over the cone is presented, §which results in reduced vibration of the §drillstring. Second a new design for the bit s §bearings is introduced that is capable of operating §in harsh environments.
