| 中文摘要: |
| 北黄海盆地是我国海域油气勘探的新区，成藏条件及其时空匹配研究薄弱，是制约该区油气勘探取得突破的重要基础地质问题之一。通过岩心、钻井、测井及地震资料等的综合分析，对中生界构造格架下的沉积充填及有利生储盖组合特征进行了系统研究。结果表明，北黄海盆地中生界为断陷湖盆，中侏罗统以湖泊沉积为主，上侏罗统主要发育三角洲-湖泊沉积体系，下白垩统发育扇三角洲-湖泊沉积体系。北黄海盆地中生界发育2套有利的生储盖组合，上侏罗统上部的半深湖相暗色泥岩有机质丰富，构成研究区主力烃源岩，与下白垩统扇三角洲储集砂体及其上部滨浅湖泥岩组成的复合型组合，为空间匹配最好的生储盖组合；上侏罗统烃源岩与其中下部三角洲河道砂体组成的倒灌式间断型组合，为另一套较有潜力的组合，储层物性及断裂-不整合面输导是决定生储盖组合优劣的关键。 |

| The North Yellow Sea Basin is a new exploration area in china sea area. The weak research on petroliferous condition and its spatio-temporal matching, is one of the important basic geological problems, which restricts the exploration activity in North Yellow Sea basin. Based on the synthetical analysis of core, drilling, logging, seismic data, the sedimentary filling and favorable source-reservoir-seal rock assemblage of Mesozoic have been researched. The results show that the Mesozoic of North Yellow Sea Basin is a fault lake basin. There mainly develop lake depositional system in Middle Jurassic，delta-lacustrine depositional system in Late Jurassic, and fan delta and shore-shallow lacustrine depositional system in Lower Crataceous. There are two favorable source-reservoir-seal rock combinations in Mesozoic. The organic matter in dark colored mudstone of semi-abyss facies enriches in the upper of Upper Jurassic, which are the main hydrocarbon source rocks, and make up complex source-reservoir-cap combinations together with fan deltaic reservoir rocks and coastal shallow lake cap of Lower Crataceous. The combinations have the best temporal-spatial configuration. Together with deltaic channel reservoir rock of Upper Jurassic, the hydrocarbon source rocks of Upper Jurassic make up flowing-backward discontinuous source-reservoir-cap combinations, which are other potential combinations. The reservoir physical property and the development of fault and unconformity are the key factors to decide the feature of source-reservoir-cap combinations. |
