Drilling Fluid Technology for Shale Oil Exploration and Development in Daqing Oilfield

  • 摘要: 为了解决大庆油田齐家-古龙区块页岩油水平井井壁失稳的问题,对古龙区块地质特征、施工难点和失稳机理进行总结分析。针对施工中遇到的井壁稳定、钻井液流变性控制、井眼净化等油基钻井液技术难题,提出相应的技术对策。优选SFD-1、无荧光防塌剂BY和Soltex等关键封堵处理剂,并对目前使用的油包水钻井液配方进行优化和室内评价。实验结果表明,优化后的钻井液具有良好的性能,高温高压滤失量小于3 mL,抗岩屑侵可达30%。该钻井液技术在大庆油田古龙区块**2HC井进行现场试验,施工顺利,井下无复杂事故发生,能够解决长水平段井眼失稳问题,在大庆油田页岩油勘探开发中具有应用前景。
