| 对惠民凹陷沙四段10个砂岩样品中的储层烃和包義体烃进行了分离和色质分析。结果表明:临南地区正构烷 烃中姥鲛烷略占优势，阳信地区正构烷烃屮植烷占优势，检测出微弱含量的和p-胡萝卜烷;包裹体烃和储层烃具 有明显的湖相泥岩地球化学特征，生物标志物表明烃类母质富含湖相浮游植物和陆源高等植物;临南洼陷储层烃指 示原油母源为淡水~微咸水沉积环境,阳信洼陷储层烃和包裹体烃母质沉积环境为微咸水沉积环境;惠民凹陷沙四 段包裹体原油大部分为成熟油,来自沙四上烃源岩,储层油是沙三下低熟烃源岩和沙四上成熟烃源岩混合油;惠民 凹陷油气成藏时间有两期注人,一期为东营组沉积时期，二期为馆陶一明化镇组沉积时期。 |

| Abstract: |
| Tlie inclusion and reservoir hydrocarbon d 10 samples of sandstone of member 4 of Shahejie formation in Huimin depression were separated and detected by GC-MS. Tlie results show that the pristane predcamnated in Linnan sag and the phytane predominated in Yangxin sag. A little content of 7- and carotenes were detected in n-aikanes. Inclusion hydrocarbon and reservoir hydrocarbon have distinct geochemical characteristics of lacustrine mudstone. The biomarker distributions show that the parent material types of these hydrocaii)ons are abundant rf lacustrine phytojdankton and terrigenous higher plants. Reservoir hydrocarbon of Linnan sag indicate that its source rocks are deposited under fresh >^ater and brackish water environment. The source rocks of inclusion and reservoir hydrocaiiwn within Yangxin sag are deposited under brackish water environment Most d inclusion hydro carbon in Htiiimn depression are mature oils and stem from member 4 of Shahejie formation- A few reservoir hydrocarixm originate from the immature source rock of member 3 and mature source rock d member 4. Hie accumulation phases of hydrocarbon reservoirs in the south slope are divided into two phases: the sedimentary period of Dongying formation and the sedimentary period of Guantao-Min^iuazhen formation. |
