摘　　要：复合关系的主要特征是指断层于不同时期发育在同一地区,联合关系的主要特征是指断层于同一地区且同期发生。这两种不同的断层组合关系形成不同的断块类型并影响其圈闭的可靠性。通过理论分析及南阳凹陷典型断块圈闭的断层组合关系及钻探结果,可知由断层复合关系而成的断块圈闭比由断层联合关系而形成的圈闭可靠性高,断层联合关系形成的圈闭可靠性与传递斜坡的演化程度有很好的相关性。In terms of the concept of fault occurrence time and extension space,this paper classifies time-space relation into compound relation and combined relation.Compound relation means faults develop in a same area in different periods,while combined relation means faults develop in a same area and same period.These two different relations form different fault block types and influence the reliability of their traps.Theoretical analysis and case study on several typical fault block traps in Nanyang Sag as well as drilling results show that compound relation leads to a high reliability of fault block traps,while the reliability of combined relation depends on evolution degree of transform faults,and it has close relation with evolution degree of transform slopes.
