摘要
目前大位移井已成为开发边际油田的最有效手段之一,其中的钻井液技术关系到大位移井的成败。从降低摩阻和扭矩、保持井眼清洁、维持井壁稳定3个方面总结分析了大位移井钻井液的关键技术问题,并提出了相应的解决措施,同时综述了近年来国内外在大位移井钻井液关键技术方面取得的研究进展,最后预测了大位移井钻井液技术在未来一段时期的发展趋势。
At present, extended reach well is becoming one of the most effective means for developing marginal field.The drilling fluid technology, which is related to the success of extended reach well.The key technical issues of drilling fluid is mainly including reducing frictional resistance and moment of torsion, keeping borehole-cleaning, stabilizing borehole wall.The relevant technology measures are proposed.And the development in the key technologies at home and abroad is described simultaneously.Finally, the trends of drilling fluid technology for extended reach well in the coming period are forecasted.
