摘要:

由于独特的构造演化,冀中坳陷潜山圈闭十分发育,从而成为重要的勘探领域。冀中坳陷潜山构造带可以划分为陡坡、缓坡和中央断裂潜山构造带3种类型。根据中央断裂潜山构造带的构造发育特征、储盖组合特征、封闭保存特征以及油气供给方式,将中央断裂构造带潜山油气成藏划分为3种模式,即:以任丘潜山构造带为代表的早隆-中埋-晚稳定型成藏模式、以河西务潜山构造带为代表的早埋-中隆-晚稳定型成藏模式、以及以肃宁潜山构造带为代表的早隆-中埋-中稳定型成藏模式。研究表明,构造作用控制潜山的规模和油气的供给方式,对潜山储层的发育及油气的保存也有重要的影响。3种模式中以早隆-中埋-晚稳定型各种成藏要素匹配最好,成藏条件最佳。

Abstract:

The buried-hill traps and reservoirs were well developed in Jizhong Depression, because of its particular structural evolution pattern. The buried-hill structural belt in Jizhong Depression can be classified into three types of steep slope belt, gentle slope belt and central faulted structural belt. According to the characteristics of structural development, reservoir-cap rock assemblage, sealing-storage property and hydrocarbon sources in the central faulted structural belt, three reservoir-forming patterns were identified, including the early uplifted, middle buried and late stabilized pattern such as the Renqiu buried-hill structural belt, the early buried, middle uplifted and late stabilized pattern such as the Hexiwu buried-hill structural belt and the early uplifted, middle buried and middle stabilized pattern such as the Suning buried-hill structural belt. The research indicated that tectonics controlled the buried-hill size and hydrocarbon source types and also had the important effects on the development of buried-hill reservoirs and hydrocarbon storage. Among the three reservoirs-forming patterns, the first one is the best in element matching relationship and the most optimal in reservoir-forming conditions.
