    摘要
  • 摘要: 针对川西南部地区沙湾组、峨眉山玄武岩存在严重井壁失稳、垮塌卡钻复杂频繁的难题，结合岩石失稳机理分析及现场工况分析，优选出一套适用于该井段的强抑制、强封堵型钻井液体系。该体系的滚动回收率达99.98%，FLHTHP为3.6mL，FL'HTHP为4.8 mL，FL砂床为4.4 mL。并设计了专项封堵段塞，制定了封堵段塞施工工艺。钻井液配方为：（0.5%~2.0%）土+（0.5%~1.5%）PAC-LV+（5%~6%）SMP-3+（2%~3%）JNJS-220+（0.3%~1.5%）NaOH+（1%~3%）FT+（0.1%~0.3%）聚合醇+（0.4%~1%）CQ-SIA+（6%~8%）WND+（5%~10%）有机盐+3%超细碳酸钙+重晶石。认为应提高随钻堵漏能力、增强泥饼井壁吸附性及黏弹性、在井壁上形成一层具有防渗透和防冲刷能力的封堵层，减缓井下机械碰撞、钻井液冲刷、应力激动对岩层的二次破坏。

     

    Abstract: Severe borehole wall destabilization and pipe sticking caused by borehole wall collapse have long been encountered in drilling the Shawan formation-Ermeishan basalt formation in southwest Sichuan Province. A drilling fluid with high inhibitive capacity and plugging ability has been formulated based on the analyses of the mechanisms of borehole wall instability and field operations. In laboratory evaluation of the drilling fluid, the percent recovery of shale samples tested with the drilling fluid was 99.98%, the HTHP filter loss was 3.6 mL, the HTHP water filter loss was 4.8 mL, the HTHP filter loss tested on a sand bed was 4.4 mL. A plugging slug used with the drilling fluid and a technique of using the plugging slug was also designed. The formulation of the drilling fluid is:(0.5%-2.0%) bentonite + (0.5%-1.5%) PAC-LV + (5%-6%) SMP-3 + (2%-3%) JNJS-220 + (0.3%-1.5%) NaOH + (1%-3%) FT + (0.1%-0.3%) poly glycol + (0.4%-1%) CQ-SIA + (6%-8%) WND + (5%-10%) organic salt + 3% ultrafine calcium carbonate + barite. It was considered practical and feasible that mud loss control while drilling should be strengthened and the adhesive ability and viscoelasticity of mud cakes be improved. High quality mud cakes protect the borehole wall from being washed and keep drilling fluid out of borehole wall. This will mitigate secondary damage of borehole wall by downhole mechanical collision, drilling fluid washout and pressure surge.
