侧钻井技术在复杂断块油藏开发中后期剩余油的开挖具有较大的优势,在国内外油田中应用也较广泛,在苏丹南部的事故井的处理、采油工艺多样性实验中进行了很好的应用。本文介绍了∮95mm小井眼套管的研发历程、新型射孔器的研制及侧钻井投产原则,同时从封堵改层技术、机械卡封改层、封堵封窜工艺、防砂工艺及特种小油管的应用几方面着重探讨分析了侧钻井采油工艺配套技术。
Lateral drilling technology has great advantages in the excavation of remaining oil in the middle and late stages of the development of complex fault block reservoirs and is widely used in oilfields at home and abroad. In the experiments of handling accident wells and oil production process diversity in southern Sudan, Very good application. In this paper, the development history of ∮95mm slimhole casing, the development of new perforator and the commissioning principle of lateral drilling are introduced in this paper. At the same time, Several aspects of the application of tubing analysis and analysis of the sidetrack drilling technology supporting technology.
