今年五、六月份,中国海洋石油南海西部公司的两口初探井先后钻获工业性气流。经测试,乐东20-1-1井日产天然气20万m~3;涠5-2-1井日产天然气14.2万m~3。这两口井的钻探成功进一步展示了莺歌海盆地和北部湾盆地油气勘探的良好前景。南海西部石油公司钻探这两口初探井的目的,是为了进一步摸清莺歌海盆地和北部湾盆地含油气构造的地质规律,增加南海油气开发的后备地质储量。初探井的钻探成功不仅为石油地质研究的深入进行提供了重要的资料,而且为下一步评价井的钻探奠定了良好的基础。
In May and June of this year, the two pioneering wells of China National Offshore Oil Corporation in the South China Sea have successively drilled industrial airstreams. After testing, Ledong 20-1-1 well Nissan 200,000 m 3; 涠 5-2-1 well Nissan 142,000 m 3. The drilling success of these two wells further demonstrates the good prospects for oil and gas exploration in the Yinggehai and Beibu Gulf basins. The purpose of the South China Sea Western Petroleum Company to drill these two exploration wells is to further find out the geologic rules of the oil-gas structure in the Yinggehai Basin and the Beibu Gulf Basin and to increase the reserve geological reserves for the development of the South China Sea oil and gas. The success of drilling in exploratory wells not only provided important information for the further research of petroleum geology, but also laid a good foundation for the next drilling of evaluation wells.
