摘要
在页岩油勘探开发初级阶段,对“甜点”储层发育区的认识以及预测是储层改造和水平井钻探成功的关键,能够有效加快非常规资源的利用。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,但目前处于勘探开发初级阶段,尚未取得重大突破。通过对饶阳凹陷沙一下亚段页岩油烃源岩及“甜点区”进行录井评价研究,对烃源岩指标进行归类统计,结合烃源岩评价成果对“甜点区”录井资料响应特征进行研究,对页岩油“甜点区”进行预测,最终深化了对页岩油勘探“甜点区”的认识,并在此基础上提出多项勘探建议,在圈闭目标发现和评价等方面发挥了重要作用。
In the initial stage of shale oil exploration and development,the understanding and prediction of"sweet spot"reservoir development area is the key to success of reservoir reconstruction and horizontal well drilling,which can effectively accelerate the utilization of unconventional resources.Shale oil in Raoyang depression,as a key reserve replacement area in Huabei oilfield,has great exploration potential,but no major breakthrough has been made because the exploration and development work is in the primary stage.Based on the study of mud logging evaluation of shale oil source rock and"sweet spot"of lower Sub-Member of the first Member of the Shahejie Formation in Raoyang depression,this paper classifies and statistically evaluates the index of hydrocarbon source rock,and studies the response characteristics of mud logging data of"sweet spot"combined with the results of hydrocarbon source rock evaluation,so as to predict the"sweet spot"of shale oil.Finally,it deepens the understanding of the"sweet spot"of shale oil exploration,and a number of exploration suggestions are put forward,which play an important role in the discovery and evaluation of trap targets.
