\u0421\u041eNE ROLLER BIT BIG DIAMETER MULTIPLY REDUCED ADMISSION ON THE KEY OUTPUT PARAMETER<\/strong>

Bogomolov R.M. \u2013 Doctor of Engineering Science, Honored Mechanical Engineer of the Russian Federation, Professor, Head of the basic department of \"Innovative technologies\" of JSC \"Volgaburmash\" at the department \"Technology of mechanical engineering\", Professor of the department \"Drilling of oil and gas wells\" of SamSTU, bngssamgtu@mail.ru bngssamgtu@mail.ru<\/a>

Key words: <\/strong>cone roller bit, a paw, section, corpus, the admission on a radial beating, constancy of the size of a chisel.

Results of researches and experiments on production and assembly of the roller bit big diameter with multiply redused admissions on the key output parameter \u2013 a radial, and constancy of the size on diameter of a chisel are given. In spite of the fact that the size of these ambissions regulated by the International API standard is estimated in millimeter shares, it has huge impact on drilling indicators \u2013 an average drilling, mechanical speed, driving meter cost, when drilling millions of meters of wells. Over a problem of reduction of the sizs of the specified admissions years all leading drill bit firms of the world work hard. The in is less these than the admission, the competitiveness and prestige of sales is higher, the prices of chisels are higher.<\/p>\n
