摘要
文章利用有限元方法分析泌阳凹陷Tg和T56构造应力场特征, 得出应力分布图和构造位移图。根据应力场分析认为Tg、T56的构造应力场具有继承性;凹陷东缘陡坡区、南缘陡坡区等强张应力分布区是有利的油气运移、聚集区。
Abstract
By using the finite element method, this paper analyzes the character of the tectonic stress field of Tg and T56 in Biyang Depression. We conclude that T56 succeeds to Tg in the character of tectonic stress field, and there are two strong tectonic stress field areas in Biyang Depression:one is at eastern escarpment and another is at southern escarpment, where are the beneficial areas of hydrocarbon migration and accumulation.
