| 摘 要： | 东营凹陷中央隆起带是胜利油田油气最富集的地区之一,前人对东营凹陷中央隆起带进行了诸多方面的研究,但对中央隆起带不同区域的差异隆升过程及构造形态缺少对比。该文通过平衡剖面的绘制,重塑了东营凹陷中央隆起带不同区域的差异构造形态及演化过程。结果表明,中央隆起带东段辛镇构造带断裂活动从沙三开始,沙二沉积期构造雏形基本显现;东营组沉积期构造格局基本定型;馆陶组沉积期断裂数量、构造幅度进一步增大;到明化镇组沉积期,构造形态发展为现今状态。中央隆起带西段梁家楼-现河断裂带自沙四沉积期开始发育,沙三末期构造雏形基本显现;沙二沉积阶段构造幅度加大,构造形态基本定型;东营组沉积阶段构造形态进一步扩大,到明化镇组沉积阶段,发展为如今构造形态。

| Abstract: | The central uplift belt of Dongying depression is one of the most enrichment area of oil and gas in Shengli oilfield. Many researchers have been carried out in this area. But comparative study on uplift process and structural form in different regions is lack. Based on the drawing of balanced section, tectonic morphology and the differential tectonic evolution process of the central uplift belt of Dongying depression have been reconstructed. It is showed that Xinzhen tectonic fracture in east section start from the third section of Shahejie formation, and the embryonic form of the structure in the second section of Shahejie formation has basically appeared. Structural pattern has been formed basically in the sedimentary period of Dongying formation. The number of faults and the tectonic extent of Guantao formation has increased furtherly during the sedimentary period of Guantao formation, and present condition of structures has been formed in the sedimentary period of Minghuazhen formation. Liangjalou-Xianhe fault belt in the west section of the central uplift zone has been developed from the fourth section of sedimentary period of Shahejie formation, the embryonic form of the structure of the third section of Shahejie formation has appeared basically, structural form of the sedimentary period of second section of Shahejie formation has increased and the structural form is basically formed. Structures expand furtherly in Dongying formation and develop to present form in Minghuazhen formation. |
