Description

вы пласта сплошным забоем или при помощи колонковых долот с отбором керна, при этом циркулирующим агентом служит газ (например воздух), о предотвращает глинизацию трещин и стенок скважины по всей высоте интервала сбойки. Посредством исключени  глинизации указанного интервала при .прочих услови х возможно увеличение сбоечного рассто ни  между скважинами, что способствует сокращению эксплуатационных скважин. Одновременно обеспечиваетс  сокращение спуско-подъемных операций бурового инстру 1ента и сокращение объема буровых ребот на величину зумпфа в подстипаю щих породах, а это повышает эффeJtтивнocтfo газификации угл .You use a solid bottomhole or coring bits with coring, while the circulating agent is gas (for example, air), and it prevents the formation of cracks and borehole walls over the entire height of the spacing interval. By eliminating the claying of the specified interval under other conditions, it is possible to increase the well spacing between the wells, which contributes to the reduction of production wells. At the same time, a reduction in the launch and lift operations of the drilling tool and the reduction in the volume of drilling discharges by the sump value in the supporting rocks is provided, and this increases the efficiency of coal gasification.
