概况盆地东部断斜带中有一个低背斜构造。地面构造闭合面积176平方公里,闭合幅度1880米。西翼地层倾角50°—70°,东翼25°—52°。地下断层发育。已被钻探证明为高压、高产、多产层的气田。1971年钻探的10号井在三迭系地层中又获得了轻质原油。 1967年280、281队曾做过27公里地震剖面。1970年10月至1971年4月202队进行了地震详查,完成了“以高点、轴线、断层为重点查明二、三迭系构造形态”的地质任务。
Overview There is a low anticline structure in the eastern fault zone. The ground structure of a closed area of 176 square kilometers, closing an interval of 1880 meters. West Wing stratum dip 50 ° -70 °, east wing 25 ° -52 °. Underground fault development. Has been proven to be high pressure drilling, high yield, multi-layer gas field. Well No. 10, drilled in 1971, gained light crude oil in the Triassic strata. In 1967 280,281 teams had done 27 km of seismic sections. From October 1970 to April 1971, the 202 teams carried out a detailed investigation of the earthquake and completed the geological task of “ascertaining the structural forms of the second and third Diego systems focusing on high points, axes and faults.”
