1937—1957年这二十年间,四川盆地的油气勘探处于早期阶段。这期间的突出特征是:在勘探技术比较落后的条件下,主要依靠盆地边缘地质调查,发现地面构造;以油气苗、油气显示层位确定目的层;背斜高点打钻找油气,逐步探索
During the two decades from 1937 to 1957, oil and gas exploration in the Sichuan Basin was at an early stage. The salient features during this period are: the geologic survey of the basin edge is mainly to rely on the basin edge geological survey to find the ground structure; the target layer is to be determined by the oil and gas seedling and the hydrocarbon-oil-bearing horizons; the high anticline anticline is looking for oil and gas to explore gradually
