摘要：

胜利油田东部探区目前已进入高勘探程度阶段。面临严峻的勘探形势，胜利油田勘探工作者本着思想再解放、认识再创新的理念，精细工作、开拓进取。2013年，在东部老区勘探程度最高的东营凹陷发现了胜利油田东部探区第75个油田——青南油田。回顾青南油田的发现历程，每次认识的创新和观念的转变都给青南地区的勘探工作带来了新的转机。具体表现为：①由斜坡带构造向洼陷带岩性的战略转移突破了青南洼陷工业油流关；②由深水浊积扇向滨浅湖滩坝的认识转变加快了青南洼陷的勘探步伐；③由运移不利区向运聚有利区的观念转变明确了青南洼陷的整体规模；④由满洼滩砂向坝砂局部发育的模式转变推动了老油区新油田的发现。青南油田发现过程中的每个关键点无不体现了创新认识、转变观念的重要性，但提出创新认识的背后是勘探工作者扎实的基础工作和技术上的不断革新。

Abstract:

After years of intensive exploration,blocks in eastern Dongying Depression of Shengli Oilfield Company yielded few and few new discoveries in past couple years.Explorationists of Shengli Oilfield Company wisely realized then that new mindsets and open mindness were urgently needed to guide further fine explration of these aging blocks.Then in 2013,the 75^th discovery-Qingnan Oilfield-was disoveried in eastern blocks of Dongying Depression.This seccess can be attributed to the following reasons:an exploration strategy shift from structural traps on slopes to lithologic traps in sags;a shift of understanding of sedimentary settings from deep turbidite fan to shore-shallow lacustrine;an exploration view turning from unfavorable migration zones to favorable migration zones;a change of understanding of sedimentary facies from beach-sandbodies of subsag-scale to local sand bars.These reasons all made the importance of new mindsets and open mindness to stand out in each critical step of discovering the field.However,what behind all these are still concrete basic works and innovative technologies.

Key words: mindset change, exploration in mature blocks, Qingnan oilfield, blocks in eastern Dongying Depression
