摘要
利用平衡剖面技术以w2测线发育过程中的中间阶段为例,对乌尔逊凹陷的构造演化进行了分析,认为大磨拐河组沉积时期为稳定拉张阶段,主要受古地形控制;伊敏组沉积时期为断陷萎缩阶段.平衡剖面技术的应用有助于进行地质构造解释与选择油气勘探目标.
Balanced cross section technology is used to measure the tectonic evolution of Wuerxun depression by line w2 intermediate stage in the development.It is claimed that Damoguaihe group is the stably extent phase during the deposition stage,mainly controlled by the ancient terrain.Yimin group is contracted during the faulted phase.Balanced cross-section technology helps to explain the geological structure and select oil and gas resources.
