摘要

摘要: 针对苏丹Azraq地区地层特点,对提高机械钻速的钻井液性能参数进行研究,根据理论和实验优化钻井液性能参数。调整钻井液滤失量为6~8 mL,塑性黏度为15~20 mPa·s,动切力为10~15 Pa,动塑比为0.75 Pa/mPa·s。根据优化的钻井液性能参数,采用无土相的硅酸盐钻井液体系,并通过实验确定钻井液配方。现场应用证明,新的钻井液工艺能显著提高Abu Gbura地层的机械钻速,机械钻速由6~8 m/h提高到12~18 m/h,缩短了完井周期。Azraq K-9井创造了该地区完井时间的最短记录。

Abstract: Optimization of drilling fluid property was studied in laboratory to aim at rate of penetration (ROP) in Azraq area in Sudan. The optimized drilling fluid had filter loss of 6-8 mL, plastic viscosity (PV) of 15-20 mPa·s, yield point (YP) of 10-15 Pa and an YP/PV ratio of 0.75 Pa/mPa·s. A clay-free silicate drilling fluid with these properties was formulated through laboratory experiment. With this drilling fluid the ROP was increased from 6-8 m/h to 12-18 m/h in the Abu Gbura formation. The well Azraq K-9 was completed in the shortest period of time in this area.
