摘要:
海洋深水钻井过程中,为防止由于钻遇浅水流而导致套管和钻杆完整性被破坏,需要对钻遇浅水流后砂水对环空的冲蚀影响规律进行分析。利用CFD软件在液固两相流和冲蚀理论基础上,建立深水钻井环空三维流场模型,模拟计算了砂水进入套管环空时对其的冲蚀影响。结果表明,最大冲蚀率、平均冲蚀率随着高度增加有增大趋势,在近出口处有较大的冲蚀磨损。另外流速、质量流率和粒径都对冲蚀结果有不同程度的影响。在考虑高压浅水流砂体对套管环空的冲蚀破坏影响过程中需要结合砂体性质、地层压力、埋藏规模和深度综合考虑。
Abstract:
During the process of deepwater drilling, in order to prevent the integrity of casing and drill pipe from being damaged by the drilling of shallow water flow, the influence of sand water erosion upon annulus which caused by drilling shallow water flow needs to be analyzed. Based on liquidsolid twophase flow and the theory of erosion, CFD software was used to establish a threedimensional annular flow field model for deepwater drilling. The effect of sand on the erosion of casing annulus was simulated. The results show that the maximum erosion rate and the average erosion rate increase with increase of height. In addition, flow rate, mass flow rate and particle size all have different degrees of impact on erosion results. Considering the impact of highpressure shallowflow sand bodies on erosion damage of casing annulus, factors such as sand body properties,formation pressure,burial scale and depth need to be considered comprehensively.
