羊八井热田勘探七九年进展很快，四月初用SPJ-300型转盘水井钻机钻进，七月中旬已完工2井：14号井（孔深458.38米），8号井（孔深213.55米）。14号井钻进中遇多层地下径流，漏失严重；地下水中硫化氢含量多；多次出现断钻杆、钻铤事故。8号井浅层压力梯度高，易井喷，1243井队工人、技术人员和勘探所援藏小组全体同志采取了相应技术措施后，两个孔都顺利完工。 The Yangbajain thermal field exploration progressed rapidly in 1979 and was drilled with a SPJ-300 rotary well drilling rig in early April. Completed in mid-July, No. 2 well was No. 14 (hole depth 458.38m), No. 8 well (hole depth 213.55 meters). In case of drilling on the 14th well, multi-layer underground runoff occurred with serious loss; the content of hydrogen sulfide in groundwater was high; and accidents such as broken drill pipe and drill collar occurred many times. Well No. 8 has a shallow shallow pressure gradient and is prone to blowout. After all the 1243 well workers, technicians and all the comrades in the exploration group to assist Tibet took corresponding technical measures, the two holes were successfully completed.
