摘要: 随着近些年饶阳凹陷蠡县斜坡–肃宁洼槽沙一下亚段烃源岩层段岩心分析资料的积累和丰富，有必要对其生烃量进行定量评价。本文通过对饶阳凹陷蠡县斜坡–肃宁洼槽沙一下亚段(Es1x)烃源岩岩心样品进行地化特征统计，以低成熟度的烃源岩样品进行高温热模拟实验为基础，利用化学动力学方法计算饶阳凹陷蠡县斜坡–肃宁洼槽沙一下亚段烃源岩生烃量。研究结果表明：饶阳凹陷蠡县斜坡–肃宁洼槽沙一下亚段烃源岩有机质丰度较高、类型主要为II1-I型、处于低熟–成熟热演化阶段；其生烃门限大约为3000 m，约在3500 m开始大量生烃；该烃源岩以生油为主，生油、生气量分别为7.14 × 108 t和0.21 × 1011 m3，所能聚集的油、气资源量分别为(0.36~1.43) × 108 t和(0.001~0.004) × 1011 m3。
Abstract: Because of the accumulation and wealth of the core analysis data from the lower part of first member (Es1x) source rocks in Lixian Slope-Suning Subsag of Raoyang Sag in recent years, it’s ne-cessary to evaluate the hydrocarbon-generation amount of the Es1x source rocks. The geochemical characteristics of core samples from the Es1x source rocks in Lixian Slope-Suning Subsag of Raoyang Sag were analyzed. The hydrocarbon-generation amount of the Es1x source rock in Lixian Slope-Suning Subsag was calculated using the chemical kinetics, which is based on the high- temperature thermal simulation of low maturity source rock samples. The results show that: the Es1x source rock in Lixian Slope-Suning Subsag is high richness of organic matter, good type (II1-I), and the thermal evolution stage is from low-mature to mature. The threshold of hydrocarbon generation of them is about 3000 m, and beginning to quickly generate hydrocarbon at about 3500 m. The source rocks of Es1x are mainly generated oil. The amounts of generated oil and gas are 7.14 × 108 t and 0.21 × 1011 m3. The oil and gas resource are (0.36 - 1.43) × 108 t and (0.001 - 0.004) × 1011 m3 from the Es1x source rocks in Lixian Slope-Suning Subsag.
