摘要: 济阳坳陷经过50余年勘探,已整体进入成熟勘探阶段,勘探程度越来越高。通过勘探发展阶段、基于"层单元"基础上的剩余资源潜力和高效增储方向分析,明确了近期勘探主攻方向并提出了下一步勘探工作对策。研究结果表明,济阳坳陷剩余资源依然丰富;重新认识前期主力增储类型河道砂岩、陡坡砂砾岩、滩坝砂岩和浊积砂岩近期仍能发现规模储量;精细分析沙四上亚段-东营组断陷期主力含油层系的储量"空白区",可落实一批效益储量阵地;转换思路认识老区新层系和新区带能不断取得新发现;页岩油气和煤成气等非常规资源是济阳坳陷中长期接替的资源。通过解放思想解放资源、创新理论引领、攻关技术支撑和强化管理推动,济阳坳陷将保持较长的稳定增储期。

Abstract: After more than 50 years, the Jiyang depression has entered a mature exploration stage on the whole and the exploration degree is getting higher and higher. Based on the analysis of "layer unit"-based remaining resource potentials and effcient reserve increase targets in the exploration and development stage, the future exploration targets have been identifed and the future exploration plan has been proposed. The study results show that the remaining resources in the Jiyang depression are still abundant; re-recognition of previous primary reservoirs involving channel sandstone, steep-slope glutinite, beach-bar sandstone and turbidite sandstone can fnd more large-scale reserves; fne analysis of the "blank reserve area" in the main oil-bearing reservoirs formed during the fault and depression of the Sha 4 and Dongying Formation can identify a series of proftable reserves; re-understanding of new strata and zones in old exploration areas using new principles can continuously make new discoveries; and unconventional resources such as shale oil and gas and coal-formed gas are succeeding resources in middle and long terms in the Jiyang depression. The Jiyang depression will keep a long-term and stable reserve increase based on re-recognition of remaining resources, innovative theories, advanced technology and effective management.
