华北油田隐蔽油藏勘探实践与认识

随着勘探的不断深入,华北油田富油凹陷构造油藏的勘探程度越来越高,勘探对象日趋复杂,勘探难度越来越大。面临勘探现状,华北油田认真分析勘探形势,立足资源基础,解放思想,积极转变勘探观念,有意识地加强隐蔽油气藏的深入研究与勘探,先后在冀中坳陷的饶阳凹陷、二连盆地的巴音都兰凹陷、乌里雅斯太凹陷等发现了多个规模富集的隐蔽油藏。通过隐蔽油藏的勘探实践,取得了四点主要认识、六点重要启示,对今后深化华北油田隐蔽油藏的勘探具有重要的指导作用。

In-depth Study and Exploration Practice of Subtle Oil Reservoirs of Huabei Oilfield

With progress continuously made in exploration, the oil reservoirs of oil-enriched depression structures of Huabei Oilfield have become more and more difficult for exploration. Facing such situation, Huabei Oilfield has made in-depth analysis and enhanced exploration of the subtle oil and gas reservoirs. As a result, a number of subtle oil reservoirs have been discovered in Raoyang sag of Jizhong depression as well as Bayindulan sag and Wuliyasitai sag in Erlian basin, leading to six breakthroughs in oil and gas exploration. Some important knowledge and experience have been obtained from the exploration practice of the subtle oil reservoirs. They are of great significance to step up future exploration of the subtle oil reservoirs in Huabei Oil Field.
