2014年1月5日 · Abstract: The palaeogeomorphological features during the depositional periods are interpreted as important factors to control the development and distribution of sedimentary facies, and to a certain extent, to control the types and distribution of oil traps in the Wuqi oil field, Ordos Basin. In this study, the compensation impression method is ...

Through research and analysis, it can be known that the lithology of Chang 91 reservoir in block G of Wuqi Oilfield is mainly composed of feldspar lithic sandstone, lithic sandstone, and lithic feldspar fine sandstone; the pore type of the reservoir is mainly intergranular pores.

2019年7月30日 · There are three sets of source rocks in the lower assemblage of Yanchang formation in Wuqi area of Ordos Basin, and the source of Chang-8 crude oil is unknown. Through analysis of geochemical indexes of Chang-7, Chang-8, and Chang-9 source rocks and Chang-8 reservoir extracts, it is found that the relative abundance of δ13C, Pr/Ph and hopanoid ...

探井钻井地质设计能帮助找到油气圈闭，确认有开采价值的油气并了解油层数量、深度、厚度，弄清目的层的岩性和物性，评价产油气能力，分析原油性质，扩大油气钻探，进一步促进油气开发。 在20世纪末期在塔里木盆地、四川盆地的勘探中超深井越来越多。 2008年以后年完数量超越百口，其中有亚洲最深井–塔深1井深度达到8408米。 说明我国钻井技术已经日益成熟，但与美国仍有差距 ‎ [1] 。 探井地质中的不确定性主要是地层压力、地层状态、地层岩性、地层分层深度和 …
