| 摘 要： | 在对断陷盆地不整合类型、地球物理特征和多种类型不整合油藏分析的基础上，阐述了不整合的组成及其对油气运移和封堵的作用。研究认为不整合是由不整合面及上、下岩层三部分组成，不整合面对油气运聚的作用是有限的，起主要作用的是不整合面上、下物性条件好的高孔渗层或下部经风化改造后的优势通道层；不整合的封堵性与不整合的岩层组合形式有关。提出了不整合对油气运移或封堵的机理，总结了六种不整合岩层组合类型对油气运移或封堵作用的模式。

| Abstract: | Based on the analysis of the type, the geophysics characteristics of unconformity in the rifted basin and multi -type of unconformity reservoirs, the formation of unconformity and its function on oil -gas migration and seal were introduced. The unconformity consists of the unconformity surface, upper kyer and lower layer. The effect of the unconformity surface on oil-gas migration and accumulation is limited, the main effect is the upper or lower layers with high porosity, high permeability and good physical properties, or the lower predominance channel layers formed by weathering, the seal function of the unconformity is related to the combination form of the unconformable formations. Mechanism of the unconformity to oil-gas migration and seal was put forward, and six models of combination types of the unconfonnable formations to the oil -gas migradon and seal were summed up. |
