△井下作业大队积极推广大庆弹深穿透射孔 1991年该队在磨溪、金华、八角场等构造进行了15次大庆弹深穿透射孔试验,施工合格率93.8％。其中磨86、113和100等并射孔后均获工业性气流。△井下作业大队进行低毛管力酸酸化试验取得成果磨87井射孔后原日产气仅6000m~3,生产不理想。1991年12月4日对其进行酸化,挤入低毛管力酸29.8m~3,排液后用2.7mm油嘴测试,日产气3.3万m~3,增产5倍以上。该井为去年矿区获得的科学试验高产井之一,展示了上述新型酸液的广阔应用前景。△采用氯化钙压井液见效磨100井日产含硫天然气1.3万m~3,油管落井后很难处理,清水压不住,用泥
The underground operation brigade actively promoted Daqing bombs penetrating perforation. In 1991, the team conducted 15 deep penetration perforation tests in Moxi, Jinhua and Bajiaochang structures and the construction pass rate was 93.8%. Among them grinding 86,113 and 100, and after perforating both industrial air flow. △ underground operations brigade to achieve the results of the low capillary acid acidification grinding mill wells perforated wells after the original only 6000m ~ 3, the production is not satisfactory. December 4, 1991 acidified, squeezed into the low capillary acid 29.8m ~ 3, after the drain with 2.7mm nozzle test, Nissan gas 33000 m ~ 3, an increase of more than 5 times. The well was one of the high-yielding wells for scientific experiments acquired last year in the mining area, showing the broad application prospects of the new acid. △ using calcium chloride killing fluid effective grinding 100 Nissan sulfur-containing natural gas 13,000 m ~ 3, tubing is difficult to deal with after falling, water pressure can not live, with mud
