摘要
渤海湾复杂断块油气藏具有地质条件复杂、油藏类型多样、储层变化快、钻井周期短、井网一次成形等特点,在开发随钻阶段,充分利用了新钻开发井资料和高分辨率地震资料,开展了井震标定、地质目标体、沉积模式、沉积相等储层定量描述及评价研究,最终建立了储层参数预测模型,并及时准确地实现了地质模型的快速更新和完善,从而为开发早期阶段井位优化、射孔方案优化提供可靠的静态模型。实钻井资料和生产动态数据表明,所建三维定量地质模型较准确地预测了储层横向变化规律和非均质性特征。这表明海上油田复杂断块油气藏的早期开发,开展储层三维定量描述和评价是可行和必要的。
The complicated fault-block reservoirs in Bohai Bay Basin have the characteristics of complex geological conditions,diverse reservoir types,rapid change reservoir,short drilling cycle and one-time formation of well pattern.Based on this,this paper fully took advantage of the drilling data of new development wells and high-resolution seismic data to make quantitative description and evaluation of reservoir through analyzing the well-seismic calibration,depositional model and sedimentary facies in the initial development while drilling.At last,the reservoir parameters model was established,the geological model was updated and modified accurately.According to the reservoir parameters model and the updated geological model,the reliable static model for well position and perforation plan optimization was established in the early development stage.The drilling data and production dynamic data show that the three-dimension quantitative geological model established can accurately predict the lateral change rule and heterogeneity characteristics of reservoir.The three-dimension quantitative description and evaluation of reservoir are necessary and available for the complicated fault-block reservoir of offshore oilfield in the early stage of development.
