南阳凹陷自1993年转入滚动勘探开发阶段,随着滚动勘探开发工作的不断深入,东部老区滚动增储与稳产难度越来越大。近年来通过开展地震地质综合研究工作,结合油气勘探成果,以油气成藏理论为指导,分析油气藏的分布规律、成藏模式与主控因素等,在滚动勘探中取得了新突破。通过深入研究,总结出滚动勘探潜力四个方向,主要为构造主体及周缘空白带、拓展出油层系、寻找断层+岩性油气藏、老井复查。
Since 1993, Nanyang Depression has been transferred to the rolling exploration and development stage. As rolling exploration and development work continues to deepen, it is more and more difficult for the old region in the east to increase rolling stocks and stabilize production. In recent years, through the comprehensive research on seismic geology and oil and gas exploration results, guided by the theory of hydrocarbon accumulation, the distribution law of oil and gas reservoirs, reservoir forming modes and main controlling factors have been analyzed. New breakthroughs have been made in rolling exploration. Through in-depth study, the paper summarizes the four directions of rolling exploration potential, mainly for the tectonic subject and the marginal blank belt, expanding the reservoir system, looking for faults + lithologic reservoirs and old wells for review.
