渤南低凸起潜山岩性识别及储集性能预测

Buried hill lithology identification and reservoir quality forecast in Bonan low uplift

渤南低凸起潜山岩性复杂多样,以太古界花岗岩、古生界碳酸盐岩以及中生界火成岩为主,其潜山基岩的岩性与储集性能直接影响油气田的分布及其富集程度。应用复杂地震相、多种属性综合判断技术等手段来识别潜山基岩的岩性,并以调谐振幅法和地震属性聚类等方法有效预测其储集性能。通过加强对渤南低凸起潜山基岩及其储集性能的研究,有益于进一步推动潜山油气藏的勘探进程。

The buried hill in Bonan low uplift has complex lithology and mainly comprises Archeanzoic granite,Paleozoic carbonate rock and Mesozoic igneous rock.The bedrock lithology and quality of buried hill reservoir had directly affected hydrocarbon distribution and enrichment.The bedrock lithology of the buried hill is identified by complex seismic facies and multiple attributes,and the reservoir quality is forecasted by tuning amplitude and cluster analysis of seismic attributes.It is helpful to the progress of buried hill reservoir exploration to enhance the study on bedrock and reservoir properties in Bonan low uplift.
