摘要: 济阳坳陷页岩油地质条件复杂，水平井钻井完井过程中面临安全风险高、机械钻速低、井眼轨迹控制效率低、复杂时效高和固井质量差等技术难题。通过钻井工程优化设计、页岩油水平井提速提效、高性能合成基钻井液和页岩油水平井固井等技术攻关与集成应用，初步形成了济阳坳陷页岩油水平井钻井完井关键技术，并在8口页岩油水平井进行了成功应用，平均完钻井深4 402.60 m，平均机械钻速8.86 m/h，实现了济阳坳陷页岩油水平井千米水平段一趟钻完钻，复杂时效大幅降低。研究与应用结果表明，该技术能为济阳坳陷页岩油资源的有效开发提供技术支持，对我国其他页岩油区块的勘探开发也有一定的借鉴作用。Abstract: Since the geological conditions of the shale oil reservoir in the Jiyang Depression are complex, there are many technical difficulties during the drilling and completion of horizontal wells, such as high safety risk, low rate of penetration (ROP), low efficiency of wellbore trajectory control, high complex efficiency, and poor cementing quality, etc. The key technologies for the drilling and completion of horizontal shale oil wells in the Jiyang Depression were preliminarily developed, benefiting from the exploration and integrated application of optimization design of drilling engineering, ROP and efficiency enhancement for the horizontal wells, development of high-performance synthetic base drilling fluid, and cementing quality improvement of the horizontal wells. Moreover, these technologies were successfully applied to eight horizontal shale oil wells. The average drilling depth and average ROP were 4402.60 m and 8.86 m/h, respectively, indicating that one-trip drilling was realized in the kilometric horizontal section of horizontal shale oil wells in the Jiyang Depression and thus the complex efficiency was lowered significantly. This study can provide technical support for the effective development of shale oil resources in the Jiyang Depression and a reference for best practices in the exploration and development of other shale oil blocks in China.
