Drilling Technologies for Horizontal Shale Oil Well Fan Yeping 1 in the Shengli Oilfield

  • 摘要: 东营凹陷页岩油资源丰富,但油气地质条件复杂,钻井过程中常发生坍塌掉块、油气侵等井下复杂情况,为了勘查东营凹陷博兴洼陷北部沙四纯上亚段页岩含油气情况,部署了页岩油水平井樊页平1井。根据勘查目的,首先对该井进行了工程设计;然后结合樊页平1井钻遇地层的地层岩性,分析了钻井技术难点;针对钻井技术难点,研究形成了井眼轨道优化技术、合成基钻井液技术,制定了安全钻进技术措施。樊页平1井应用研究的各项技术和采取相应的技术措施,顺利完成了钻井施工,钻进过程中未出现井下复杂情况,井径扩大率小,取得了很好的实钻效果。樊页平1井顺利完钻,为胜利油田的页岩油钻井积累了经验。

     

    Abstract: The Dongying Sag possesses rich shale oil but due to its complex geological conditions of the oil and gas reservoir, downhole problems such as collapse, spalling, and oil and gas invasion are frequently encountered during drilling. A horizontal shale oil well, Well Fan Yeping 1, was deployed to explore the oil-bearing situation of shale formation at the upper Chun submember of the fourth member of the Shahejie Formation in the northern part of the Boxing Subsag of the Dongying Sag. In accordance to the exploration objectives, engineering design was made on the well. Then, with the lithology of the formation encountered during the drilling of Well Fan Yeping 1, the difficulties in drilling technologies were analyzed. On this basis, optimization technology for wellbore trajectory, the technology for synthetic base drilling fluid, and safe drilling technology were developed. With these technologies, the construction of Well Fan Yeping 1 was completed. Good results were achieved, with no downhole problems and a small hole diameter enlargement rate. The successful application of the drilling technologies to Well Fan Yeping 1 have accumulated experience for the drilling of shale oil in the Shengli Oilfield.
