摘要：

运用地球化学研究手段，对文东地区沙二和沙三段原油、油砂和泥岩进行了饱和烃气相色谱-质谱分析，认为沙二和沙三段原油来自沙三段烃源岩；通过对研究区储层流体包裹体的分析，结合原油构造演化资料，对沙二和沙三段油藏的成藏时期进行了分析。沙二段油气藏主要成藏期为东营中后期及抬升剥蚀期，主成藏期为30~17Ma；沙三段为两期油气充注，第一期为在东营初期（距今33~23Ma），为主成藏期；第二期发生在明化镇期（距今10~0Ma）之后。对文东地区成藏模式进行了分析，把文东地区油藏分为近洼原生型、油源断层控制的调整型和浅层次生型3类。

Abstract:

By analysis of saturated hydrocarbon GC-MS of crude oil，oil sand and shale samples from member 2 and 3 of Xujiahe formation，in Wendong area，it is suggested that in the study area，hydrocarbons are derived from the source rocks of member 3 of Shahejie formation.In order to further determine the oil accumulation phases of member 2 and 3 of Shahejie formation，fluid inclusions in reservoir rock also are studied，combined with information on tectonic evolution，the results show that the main accumulation period of member 2 of Shahejie formation was the late period of Dongying formation deposition and the period of its uplift-erosion，which was about 30Ma~17Ma，and that there are two phases of oil and gas filling for member 3 of Shahejie formation.The first phase，which is the main accumulation period was in the early Dongying formation deposition (33Ma~23Ma ago)，the second phase took place after Minghuazhen formation deposition (10Ma~0Ma ago).Finally，based on the analysis of accumulation model，the reservoirs in the area are divided into three types，i.e.，sag-near primary oil type，source and fault-controlled adjusted oil type and shallow second oil type.
