我厂为了解决电右供应問題,一月上旬組織人員制造工具开采天然气体,經过三天的努力,發现了天然气,计示压力高达2大气压。开采天然气的主要工具为自制的5时及2(1/2)吋鑽头各一只。鑽探开始时,先将5吋鑽头旋入地內10公尺左右,再在孔內插入內徑为2(1/2)吋長6公尺的管子两根,下面的一根管端面鋸成齿形,以便继续鑽深。同时将2(1/2)吋鑽头伸入管子內,逐步将淤泥吊出洞口,并把管

In order to solve the electricity supply problem, our factory organized natural gas exploration and production tools in early January. After three days of hard work, we found natural gas and measured pressure up to 2 atm. The main tools for mining natural gas are homemade 5 and 2 (1/2) inch drill bits each. At the beginning of the drilling, the 5-inch drill bit is screwed into the ground for about 10 meters. Two 2-in. (1/2) in. Length and 6-meter tubes are inserted in the hole. A pipe end face saw Toothed, in order to continue drilling. At the same time, insert a 2 (1/2) inch bit into the pipe and gradually lift the mud out of the hole,
