摘要
饶阳凹陷页岩油作为华北油田储量重点接替领域,勘探潜力巨大,为实现老探区富油凹陷持续增储,也为深化该区页岩油领域地质认识,通过对饶阳凹陷蠡县斜坡内带-河间洼槽带沙一下亚段108口老井地质、气测、地化、XRD衍射等各项录井资料综合分析,以录井油气层评价研究成果为基础,结合勘探开发进程,形成了适合该区页岩油领域的岩石类型、源储组合类型、烃源岩类型、物性、含油性、脆性即“三类、三性”录井评价技术,综合分析认为蠡县斜坡内带-河间洼槽带沙一下亚段满足页岩油富集条件。应用这种方法对该区新钻探11口井进行跟踪评价,解释符合率达81.5%,评价结果满足了页岩油录井评价的定量化及准确化的需要,为饶阳凹陷页岩油下一步勘探部署提供了有利地质依据。
As the key replacement area of reservoir in Huabei Oilfield,the shale oil in Raoyang Sag has huge exploration potential.To realize the continuous increase of reservoirs in oil-rich sag in the old exploration area and to deepen the geological understanding of shale oil in this area,through comprehensive analysis of geology,gas logging,geochemical,XRD diffraction and other mud logging data of 108 old wells in the lower part of the first member of Shahejie Formation of Lixian slope inner belt-Hejian sub-sag belt in Raoyang Sag,based on the research results of mud logging reservoir evaluation and combined with exploration and development process,the three types and three properties mud logging evaluation technology that was suitable for shale oil field in this area was developed,namely rock type,source-reservoir combination type,source rock type,physical property,oil content and brittleness.Comprehensive analysis suggests that the lower part of the first member of Shahejie Formation in Lixian slope inner belt-Hejian sub-sag meets the shale oil enrichment conditions.This method was adopted to track and evaluate 11 new drilling wells in this area,and the interpretation coincidence rate reached 81.5%.The evaluation results met the needs of quantification and accuracy of shale oil mud logging evaluation and provided favorable geological basis for the next exploration and deployment in Raoyang Sag.
