| 摘 要： | 鄂尔多斯盆地的形成演化进入第四阶段时,靖安油田北东部发育了延长组和延安组沉积,它们是主力产油层.区内石油产层的局部构造主要分为岩性差异压实作用所形成的局部性隆起;古地形突起上覆地层形成的披覆构造;由差异升降作用造成,但相对较少且不易与前两类区分.区内的局部构造与石油开发关系密切,直接影响油井产量.

| Abstract: | At the fourth stage of the evolution of the ordos basin, the Yanan formation and Yan'chang formation in north-east Jing'an oil fieled, were formed and became the main oil-developing layer in the district. The local structure of the oil-developing layer in the district can be divided into primarily three type: one is rock of difference pressing function becoming swells up,another is older strata rising up forming cover structure and the third one is caused mainly by difference function of ascended and descend. But it is not common and not easy to be distinguished from the other two. The relationship between the local structures and oil development is close, and it influences the production of oil well directly. |
