辽东带系指渤海辽中凹陷的东部陡坡带及辽东凸起，被辽中及辽东凹陷所夹持。辽东带油源条件好，东营组储—盖条件优越，断鼻、断块圈闭发育。但在2002年之前的15年内，国内外公司在辽东带进行了长期研究和勘探，钻了12口探井，没有发现商业油气田。经过对辽东带油气地质条件3年的深入研究，对每口失利井原因进行了再次分析，认识到该带发育东营组及沙河街组两套主力成藏组合，控制东营组成藏的主要因素是油气运移，而沙河街组能否成藏关键是储层。在此认识指导下选择研究方向，评价有利目标，经钻探发现了金县1-1大油田，储量达1.5×10⁸ m³，充分显示了科研在油气勘探中的作用。

Liaodong zone includes eastern actic region of Liaozhong sag and Liaodong uplift, which is between Liaozhong sag and Liaodong sag with good condition of source rocks and favorable reservoir-seal assemblages in Dongying formation. Meanwhile, there are many fault blocks and nose-shaped structures. However, twelve wells were drilled during 15 years without any significant business discovery by foreign oil companies and domestic petroleum enterprises before 2002. Based on deep research of geological condition and analysis on dry wells again in Liaodong zone, we recognized that two main reservoir plays existed at Dongying and Shahejie formation. Moreover, the dominative factor for Dongying is migration and the one for Shahejie is reservoir. According to this guidance, such giant oilfield JX1-1 was discovered with 150 million reserves in the end through right research direction and favorable targets evaluation, which shows great importance of scientific research in oil and gas exploration.
