| 摘 要： | 埕北30潜山带以古生界的碳酸盐岩和太古界的变质岩为主要储层，构造裂缝是主要的油气储集空间，尤其是对于太古界的变质岩来说，裂缝发育是研究区内油气聚集的主要标志，该文采用有限元方法对埕北古生界顶面的古构造应力场进行了反演，按应力性质进行了区带划分，预测了储层有利区块，预测结果应用于井位部署，取得了很好的效果。

| Abstract: | The buried hill zone in Chengbei 30 is characteristic of Paleozoic carbonate rocks and Archaean metamorphic rocks as chief reservoirs. Meanwhile tectonic seams are the main reserving space for hydrocarbon in the study area.Development of seams is the principal mark for the study of hydrocarbon accumulation, especially for that of Archaean metamorphic rocks. Finite element analysis is adopted to reverse convolute the paleotectonic stress fields of the top layer of Paleozoic Erathem in Chengbei, and division of zones is also conducted based on the property of stresses in the paper. Finally, prediction for favorable zones of reserving layers is also made, which has been applied to the arrangement of drilling and gained good effect. |
