Oil mainly distributes in high places of structure which include the blocks of Bei19, Bei38, Bei40, Bei28, Bei12, Bei14, Bei16 and Bei30. Through the analysis of relationship between the regular patterns of oil distribution and the condition of oil accumulation, the conclusion can be drawn that the oil vertical distribution of Sudeerte buried hill oil field is controlled mainly by the depth that oil migrates to basement buried hill by “down-migration”, the developing degree of oil layer, no uniformity and the adequate degree lang=EN-US style="FONT-SIZE: 14pt">n">of oil supplying, the oil horizontal distribution is controlled mainly by the area and depth that oil migrates to basement buried hill by “down-migration” and the adequate degree of oil supplying. namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
