摘要: 通过分析涠西南凹陷古湖泊沉降、充填与其断裂发育、活动速率的关系,明确了不同次级断裂对凹陷古湖泊发育演化的控制程度以及对烃源岩的分布、成熟、生烃、排烃、聚集场所等成藏条件的控制.根据影响断层封堵性的主要因素——岩性,运用概率理论定量评价断裂的封堵性及成藏的可能性,进一步明确凹陷今后勘探的主要方向.

Abstract: It is indicated that fractures control on hydrocarbon reservoir formed condition of paleolake evolution,source rock maturation and hydrocarbon distribution,generation,expulsion,migration and accumulation,the relations between paleolake settling,sag filling and rate of fractures forming were studied in the Weixinan sag,Beibu Gulf Basin.Using the theory of applied probability to quantitatively evaluate the sealing ability of the fault,which is mainly influenced by lithology of the rocks in both sides of the fault,and the probability of forming of hydrocarbon pools.

Key words: fracture, paleosedimentary, rate, fault, plugging, oil & gas reservoir
