| 摘 要： | 随着勘探程度的提高,乌伦古坳陷多年来沿用的构造单元划分方案开始凸显其不适应性。文章对原方案存在的问题进行了剖析,根据近年来钻探和地震解释成果提出了新的构造单元划分方案。新方案以中生代沉积背景为主要依据,将乌伦古坳陷划分为红岩断阶带、索索泉凹陷和乌伦古南斜坡3个二级构造单元。与原方案相比,新方案中的乌伦古坳陷面积有所扩大,斜坡带的界定使坳陷的形态及含油气差异性更趋合理。

| Abstract: | The division scheme of mesozoic structural unit of Wulungu depression in Jugar Basin,which have used for years,shows its inadaptability along with the degree of the exploration go up.In the paper,the original division scheme is analyzed and a new scheme is presented according to the drilling result and seismic interpretation result. Three Class-Ⅱstructural units(Hongyan fault zone,Suosuoquan sag and Wulungu south acclivity) are divided by the new scheme based on the Mesozoic deposition background.As compared with the original,the Wulungu depression area in the new extended to a certain extent,the definition of the acclivity make the shape of depression and difference of the hydrocarbon more reasonable than before. |
