Abstract: The targets to be found in China’s eastern faulted basins of the Paleogene System-the Neogene System become more and more subtle. With the main oil reservoirs entering their “three high” stage, it is more and more difficult for exploration and development. However, the reserves are still regarded as tremendous. It is of great significance to analyze and study future technological development. The low-graded and subtle oil and gas reservoirs in this region will be the main targets for future exploration and development. It is necessary to update the knowledge about continental source strata and accumulation efficiency, focus the study on spatial differential distribution of remaining oil and gas resources, continue to develop and perfect the trap and reservoir description and prediction technology which is dominated by 3D seismic exploration technology, and develop the wellbore technology aimed at improving single-well productivity, such as large-displacement, multi-target, horizontal well drilling technology as well as staged fracturing and volumetric fracturing technologies. It is also necessary to develop the fine exploration and development technology for marginal oil and gas reservoirs, complex geological bodies and improve the EOR technology for high and ultra-high water-cut oilfields, promoting high-efficiency development and utilization of complex and low-grade oil and gas resources.

摘要： 我国东部古近系—新近系断陷盆地待发现目标越来越隐蔽，主力油藏大都进入“三高”阶段，勘探开发 难度越来越大，但普遍认为资源潜力仍然不小，分析研究未来技术发展需求意义重大。该区低品位、隐蔽油气藏将是 未来勘探开发的主要对象，要创新陆相烃源层系油气生成与聚集效率认识，深化剩余油气资源空间差异分布研究，继 续发展完善以三维地震勘探技术为主导的圈闭、储层描述与预测技术，发展以提高单井产能的大位移、多靶点、水平 井钻井及分段压裂、体积压裂等井筒技术，发展边际油气藏、复杂地质体的精细勘探开发技术，发展整装高含水、特 高含水油藏提高采收率技术等，促进复杂、低品位油气资源的高效开发利用。
