【摘要】：通过深入分析饶阳凹陷剩余资源和勘探程度,指出饶阳凹陷还存在持续勘探的潜力,明确洼槽区、斜坡带及隐蔽型潜山为下步重点勘探领域和方向,同时梳理出深化勘探面临的地震资料碎散、构造关系与有效储层展布不清、成藏主控因素与成藏模式不明等关键问题。为了最大限度地挖掘资源,寻找更多的优质规模储量,进一步提高资源转化率,提出基于"整体认识、整体评价和整体部署"的饶阳凹陷二次勘探思路与方法,即构建全凹陷整体三维地震数据平台,重建凹陷构造、沉积、储层地质模型,量化表征油气资源空间分布,构建多领域成藏模式,优选重点领域与目标整体实施、精细勘探。自2005年以来,饶阳凹陷应用二次勘探思路与方法,相继取得油气重要发现,形成了2×108t级规模效益储量区。通过对饶阳凹陷二次勘探实践的剖析,系统阐述了其二次勘探方法、技术和经验,以期对其他类似地区或领域的油气勘探工作有所借鉴和启迪。
[Abstract]:Through in-depth analysis of the remaining resources and exploration degree in Raoyang Sag, it is pointed out that there is still potential for continuous exploration in Raoyang Sag. It is clear that the area of depression, slope zone and hidden buried hill are the next key exploration areas and directions. At the same time, the key problems such as the fragmentation of seismic data in deepening exploration, the unclear distribution of structural relationship and effective reservoir, the main controlling factors of reservoir formation and the model of reservoir formation are discussed. In order to excavate resources to the maximum extent, to find more high quality reserves and to further improve the conversion rate of resources, the paper puts forward the idea and method of secondary exploration in Raoyang sag based on "overall understanding, overall evaluation and overall deployment". That is, to construct the whole three-dimensional seismic data platform of the whole depression, to reconstruct the structural, sedimentary and reservoir geological model of the depression, to quantitatively characterize the spatial distribution of oil and gas resources, to construct a multi-domain reservoir forming model, to select the key areas and the overall implementation of the target, and to make fine exploration. Since 2005, important oil and gas discoveries have been made in Raoyang sag with secondary exploration ideas and methods, and a 2 脳 108 t scale benefit reserve area has been formed. Based on the analysis of the secondary exploration practice in Raoyang sag, this paper systematically expounds the secondary exploration methods, techniques and experiences in order to draw lessons from and enlighten the oil and gas exploration work in other similar areas or fields.
