摘要
方法应用测井、区域地质和油气藏动态资料,对欢喜岭油田上台阶稠油油藏的形成条件及分布特点进行研究。目的为该区的滚动勘探提供依据。结果欢喜岭油田上台阶生储盖在空间上具有良好的配置关系,长期广泛发育的扇三角洲前缘水道砂及早期或同期形成的多种圈闭,为油气聚集提供了有利场所;油气在长距离的运移过程中,轻质组分大量散失,重质组分浓缩聚集成稠油油藏;而有利岩相带与构造的有机配合则控制了稠油的分布。结论通过对欢喜岭油田上台阶稠油油藏形成条件和分布特点的研究,并将其研究成果进行实施,取得了齐40和齐108块的连片及齐108块扩边的成功,发现了新区欢616块,为下步滚动勘探指明了方向。
MethodThe forming
and distribution characteristics of heavy oil reservoir of going-up terrace in Huanxiling oil field
are studied together with logging, regional geology and reservoir performance data.PurposeTo
provide basis for progressive exploration in this area.ResultVery good association is formed in
source, reservoir and cap rock of the going-up terrace in Huanxiling oil field. Extensively and
long term developed fan-delta front channel sands and early or simultaneously formed multi
types of trap provide favorable place for the accumulation of hydrocarbon. In the process of
long distance migration of hydrocarbon, a great deal of lighter component were lost while
heavier component were condensed and cumulated to be heavy oil reservoir. However, the
association of favorable petrographic belt and structure controlled the distribution of heavy
oil.ConclusionSuccessful exploration has been achieved for the connection of fault block Qi-40,
Qi-108 and the extension of fault block Qi-108. A new exploration fault block(fault block 616) was
discovered which can direct the progressive exploration later on.
