摘要
禹城地区是临清坳陷东部最具潜力生油洼陷,在讨论勘探存在问题的基础上,本文综合分析了禹城地区古近系烃源岩成烃特点、油气运移方向和成藏条件。指出沙三段是禹城地区最主要的烃源岩,油气主要向南运移,南部陡坡带的岩性、砂砾岩体和古潜山油藏是禹城地区近期勘探的重点。
Yucheng area is an oil generation subsag with best potential in east Linqing depression. Based on the discussion of exploration problems, the hydroearbon generation, migration direction, and reservoir forming conditions of source rock in Palaeogene are analyzed in this paper.Es3 is the most important source rock in Yucheng area, oil and gas are mainly migrating to south, and the lithology, grit rock, and buried hill reservoir in southern steep slope are the key targets in the future exploration.
