摘要： 饶阳凹陷是渤海湾盆地富油气凹陷之一，主力烃源岩为古近系沙三段湖相暗色泥岩，具高度非均质性。应用烃源岩测井地球化学评价技术对32口探井进行分析，将离散的实测总有机碳含量数据变成连续的数据。根据总有机碳含量与氢指数相关性，实现烃源岩非均质性的分级评价，得出有机相C相和D/E相的烃源岩厚度分布模型；利用井底测温数据和古温标参数，精细标定饶阳凹陷地温场和烃源岩有机质成熟度；应用Trinity3D油气系统精细评价了烃源灶排烃强度，沙三段烃源灶排油强度为1.0×106~5.4×106 t/km2，排气强度为0.5×108~22.0×108 m3/km2

Abstract: Raoyang sag is one of hydrocarbon-rich sags in Bohai Bay basin, its major source rock is Es3 lacustrine dark mudstone with strong heterogeneity. Analysis of32exploration wells by source rock logging evaluation technique converts the discrete measured TOC data into continuous data. According to the correlation between TOC and HI, the grading evaluation of heterogeneity of the source rock is presented, obtaining the thickness distribution models in terms of C and D/E organic facies. The bottom hole temperature and paleo?temperature scale parameters are applied to calibrate distribution of geotemperature field and maturity of source rocks in Raoyang sag. Trinity3D petroleum system is used to evaluate the hydrocarbon expulsion intensity of the source kitchen, which shows that the oil expulsion intensity ranges from 1.0×106 to 5.4×106 t/km2, while the gas expulsion intensity is 0.5×108~22.0×108 m3/km2
