摘要：

根据油气成藏体系概念和层次分析法基本原理,将黄骅坳陷第三系划分为4个成藏体系和16个亚成藏体系,初步建立了成藏体系的定量评价方法。优选出烃源体、输导体和圈闭体所涉及的22个地质单因素,包括有机碳含量、有机质类型、成熟度、源岩厚度、供烃面积系数及生烃强度、断层、储层、不整合面及其空间组合等,定量评价了黄骅坳陷成藏体系和亚成藏体系的元素及成熟度。结果表明,黄骅坳陷4大成藏体系的烃源体、输导体和圈闭体三元素存在明显的差异,中部歧北成藏体系各元素发育条件最好,其次是中部歧南成藏体系,南部成藏体系较差,北部成藏体系最差。中部歧北成藏体系和中部歧南成藏体系成熟度较高;南部成藏体系和北部成藏体系成熟度较低。

Abstract:

According to the concept of petroleum accumulation systems and the basic principles of analytical hierarchy process,the Tertiary in Huanghua depression can be divided into four petroleum accumulation systems and sixteen subsystems.Quantitative evaluation method of petroleum accumulation system has preliminarily been established.22 geological factors in respect of source rocks,carrier rocks and traps have been selected,including organic carbon content,type of organic matter,maturity,thickness of source rock,areal coefficient of hydrocarbon delivery and intensity of hydrocarbon generation,fault,reservoir,unconformity,as well as their spacial combination.Quantitative evaluations of the elements and maturity of petroleum accumulation systems and subsystems in Huanghua depression show that the three elements,i.e.source rocks,carrier rocks and traps of the 4 systems are remarkably different,of which the Qibei system in the central part of the depression has the best development conditions,followed by the Qinan system in the same area,while the system in the south is relatively poor and the system in the north is the poorest.The maturities of the Qibei and Qinan systems in the central part of the depression are high,while those in the south and in the north are low.

Key words: petroleum accumulation system, element, maturity, quantitative evaluation, Huanghua depression, Tertiary
