1975年南海石油勘探指挥部在北部湾涠西南凹陷打出工业油气流。

Industrial oil-gas current was drilled out by Nanhai petroleum exploration headquarters in Weixinan depression of Beibu Gulf in 1975.

已在其中的两个弧形构造带2 0余口井获商业油气流。

The commercial oil and gas were got in more than 20 wells of two arcuate structural belts among the reservoirs.

在泥岩油气藏的有利地区，找到较发育的裂缝群，就有希望找到工业性油气流。

It is possible to find industrial oil and gas flow so long as a group of well-developed fractures are found in a favourable region of a fractured shale reservoir.
