Description
Изобретение относитс к области горной нромышленности, в часттюсти к устройствам дл бурени скважин.The invention relates to the field of the mining industry, in particular to devices for drilling wells.
Известно устройство дл бурени скважин в газодинамических угольных иластах, состо щее из нородоразрушающего инструмента и кланана.A device for drilling wells in gasdynamic coal silts, consisting of a destructive tool and a clanan, is known.
Предложенное устройство отличаетс от известного тем, что оно снабжено сальником, установленным над устьем скважины, в боковой части которого находитс патрубок с обратным клананом.The proposed device differs from the known one in that it is provided with an epiploon mounted above the wellhead, in the side of which there is a branch pipe with a reverse clan.
Такое вынолнение устройства нозвол ет предотвратить выброс угл и газа.Such a device arrangement prevents the release of coal and gas.
На чертеже показано предложеиное устройство , общий вид.The drawing shows the proposed device, the overall appearance.
Иа устье скважн111 1, предварнтельно загерметизированное с помощью цельнот нутой трубы 1 и цементного раствора с песком, устапавливаетс сальник 2, в боковой частн которого находнтс натрубок 3 с обратным клананом 4, отрегулированным на лТ,авленне,The wellhead 11 1, previously sealed with the help of a solid pipe 1 and cement mortar with sand, is fitted with an oil seal 2, in the lateral part of which there is an inlet 3 with a reverse clanan 4 adjusted to LT, avlenno,
равное горному давлению на данной глубине плюс потерн в ciicTCNie. Второй клапан 5, настроенный на то же давление, что и клапан 4, устанавливаетс в бурильной трубе 6 сразу же за буровой коронкой 7. При пагнетаннн воды в бурильную трубу в процессе бурени сначала открываетс клапан 5, а затем клапан 4, что н обеснечивает посто нное давленне в скважиие i циркул циЕО необходимого количества жидкости. При отключении пасоса клапаны 5 п 4 закрываютс , п в скважине ноддерживаетс посто нное давление.equal to rock pressure at a given depth plus lost in ciicTCNie. The second valve 5, which is set to the same pressure as valve 4, is installed in the drill pipe 6 immediately behind the drill bit 7. When pumping water into the drill pipe, during drilling the valve 5 first opens valve 5 and then valve 4, which permanently clears this pressure in the well and circulation of the required amount of liquid. When the passor is disconnected, the valves 5 and 4 close, and a constant pressure is maintained in the well in the well.
