| 摘 要： | 济阳坳陷已进入隐蔽油气藏勘探阶段,对1995年以来的预探圈闭统计分析表明,影响预探圈闭效果的主要因素为地质条件、勘探程度、地质认识、技术水平和勘探投入等.地质条件和资源规模仍是影响预探圈闭效果的决定性因素,地质条件优越的富油凹陷或区带,预探圈闭的成功率高,勘探潜力较大.预探圈闭的钻探效果与勘探程度基本呈负相关关系,勘探程度较低的古生界、深层和潜山圈闭升级率较高;勘探程度较高的古近系和中浅构造圈闭预探成功率下降.圈闭升级率的变化反映了地质认识、技术水平等对圈闭勘探效果的影响.勘探技术的发展和进步是提高济阳坳陷圈闭预探水平的有力保障,也是保持圈闭勘探不断取得新发现和突破的重要原因之一.在隐蔽油气藏勘探阶段,勘探程度较高,钻探目标复杂隐蔽,勘探风险增大,足够的预探工作量投入保证了良好的资源序列和可持续发展.

| Abstract: | The exploration of Jiyang Depression has been at the stage of subtle reservoir exploration. According to the statistics of prelimi-nary prospecting traps since 1995,the influential factors of explo-ration effect on the preliminary prospecting traps are mainly geo-logic setting,degree of exploration,geologic knowledge,technical progress,exploration investment and so on. But the elementary factors such as geologic setting and resource scale etc are still the determinative ones affecting the traps preliminary ... |
