Before the borers of TNK-VR a task costs for 5 years to reduce the term of the boring drilling of mining holes on 50%. «It is very hard plans, but we do all possible for their realization», – the director of department of building of mining holes marks «Orenburgnefti» Konstantin Kulakov. «If in March, 2009 reduction of terms of building of mining holes made at the operating boring drilling 3,96%, then in May this number was increased to 9,7%, and by year’s end plan to reduce the terms on 15,74%», – Konstantin Kulikov adds.If to compare the dynamics of changes
volumes of the boring drilling, then, as compared to 2007, it grew almost in two times. If in 2007 driving made 188 thousands of m, then in 2009 – already attained 280 thousands of m The amount of mining holes grew in two times. So, if in 2007 a booty from the bored mining holes made almost
666 thousands of tons, then in 2009 are 1072 thousands of tons. Thus cycle boring drillings of mining holes brief on 30%. from the considerable stages of reduction of term it is possible to mark a result boring drillings of mining holes on Davydovskom deposit. If yet a few years back minimum term of the boring drilling
made 265 days (vertical mining hole with a depth a 4550 m), then today the real was become by the term of the boring drilling 100 days (mining hole in a 4720 m depth and by departure a more than 1000 m). It is a mining hole 2725 and 2731, the boring drilling of which is carried out by the boring contractor of joint-stock COMPANY «OBN» on modern wellsites
settings top-driven.Similarly, in May, 2009 mining hole 115 Novo-dolgovskogo of deposit was bored for 47 days. Before such mining holes were bored no less by what for 80 days. «We walked up to 50-procentnomu reduction of terms of the boring drilling. And it is a not limit», – Konstantin talks
Fists. – In the nearest two years we plan to go out on 35 days of well-boring a depth a to 3000 m and 60 days – on mining holes in a 4300 m depth».
