长春岭地区扭动构造与油气成藏的关系

Torsion Structures and Their Relationship to Hydrocarbon Accumulation for Changchunling Area

依据最新处理的三维地震资料,对长春岭地区的扭动构造展开了精细研究。根据该区的构造特征,识别出雁列式、发辫状、"入"字型等平面组合的扭动构造样式,并进一步研究了扭动构造对油气聚集的作用,认为长春岭地区的扭动构造形成了有利于油气聚集的圈闭,同时,该区内扭动构造具有十分有利的成藏条件。因此,开展长春岭地区反转构造的研究,对于下一步的油气勘探具有重要的意义。

On the base of new processed 3D seismic data,torsion structures in Changchunling area is accurately studied.On the basis of structural feature in this area,plane combination of torsion structures such as en echelon,queue appearance,the ＂λ＂ type are recognized,and further study the effect of torsion structures to oil and gas accumulation.torsion structures provide very favorable conditions for the formation of oil and gas reservoirs.So the study of reversion structure in Changchunling area is significant for the further oil and gas exploration.
