摘要

摘要: 为了研究油气运聚过程, 以迪那2构造为地质模型, 在构造特征、储盖组合、油气来源分析的基础上建立油气运聚过程物理模拟的二维实验模型.通过模拟实验, 揭示: (1)断层是迪那2构造中油气运移的主要通道; (2)泄压区是油气运移的有利指向区; (3)毛管力及浮力在渗透性相近的砂岩中起重要作用; (4)油气总是选择优势通道运移, 在沿断层运移的同时, 也向两侧砂体中扩散; (5)油驱水之后的气驱油运移通道具有继承性的特点.

Abstract: Two dimensional experimental model of hydrocarbon migration and accumulation has been built up according to the geological model of the Dina 2 structure including the database of structure, assemble of reservoir and caprock, and hydrocarbon sources. The results indicate that (1) faults are predominant pathways for oil and gas migration in the Dina 2 structure; (2) the pressure released zones are available for oil and gas migration; (3) capillary and buoyancy play an important role in sandstone with similar permeability; (4) hydrocarbon migrates always along the predominant pathways, such as faults and associated sandstone in both sides; (5) pathways of oil and gas migration have the nature of succession, such as oil driving water and following gas driving oil.
