77年5月,广东佛山的官窑公社发现一CO_2气贮存地层,贮量相当大,第一口井开出时曾发生井喷,控制后井中还有56公斤气压,封井附近地面各积水处仍可看到有气泡不断冒出。气体成分99.6％是CO_2,只含有少量硫醇等杂质。 CO_2气除工业和食品工业上有许多用途外,农业上可用于CO_2施肥,促使作物增产,因来源不多,净化困难和施用不便等原因,只能作小范围的试验或局限在某些温室中施用。佛山这个井的发现,使大面积田块的CO_2施肥试验和应用有了方便的来源。佛山地区科委曾为此在1978年底组织过一次薄膜
In May 77, Guanyao commune in Foshan, Guangdong, discovered a CO_2 gas storage stratum with a relatively large reserve. A well blowout occurred at the opening of the first well. After the control, there was still 56 kilograms of pressure in the well, Department can still see bubbles continue to emerge. 99.6% of the gas composition is CO_2, containing only a small amount of impurities such as mercaptans. In addition to many uses of CO 2 gas in the industrial and food industries, agricultural applications of CO 2 fertilization and crop production increase are limited to small-scale experiments or limited to some greenhouses due to their limited sources, purification difficulties and inconveniences in application. In the application. The discovery of this well in Foshan has provided a convenient source for testing and applying CO 2 fertilization on large fields. Foshan Science and Technology Commission for this purpose had organized a film in late 1978
