摘　　要：通过对孔南地区反转构造的分析 ,认识到前第三纪潜山中存在断层及地形的反转两类反转构造 ,并且每类反转中又包括正、负两种反转样式。它们的演化受左旋挤压、右旋拉张两种应力场的转换控制。每种反转构造在演化过程中均形成与潜山油气藏有关的、特定的成藏条件。经分析 ,反转构造在孔南、黄骅拗陷潜山中均普遍存在 ,对其进行识别并认识 ,能使地质分析工作更加明了化、系统化 。It is realized through analyzing reverse structure in Kongnan region that there exist two kind of reverse structure —fault reverse and topographic reverse in buried hill of pre Tertiary period, and each of them contains positive and negative reverse. Their evolution has been alternatively controlled by two kinds of stress field—left lateral compression, right lateral tension. Each reverse structure has formed distinctive reservoir condition related with buried hill type reservoir in evolutional process. Inverse structures are widely existed in buried hills of Kongnan and Huanghua Depression after analysis. Identification and understanding of them can make geologic analysis work more clear and more systematic and serve for next buried hill prospecting.
