【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.更多还原
