Drilling Fluid for Tuff Formation in Block C2 of Myanmar

  • 摘要: 缅甸C2区块凝灰岩地层在钻井施工过程中存在严重井壁失稳问题。基于缅甸C2区块凝灰岩地层地质组构特征和矿物组分分析结果,对缅甸C2区块已钻井现场使用的钻井液体系进行室内研究优化,研究了一种强抑制强封堵的钻井液体系。现场应用表明,该体系有效减少了缅甸C2区块井壁坍塌等井下复杂情况,起下钻速度明显提高,井径规则程度大为改善,钻井周期大幅缩短。强抑制强封堵钻井液体系能够解决凝灰岩地层井壁失稳问题,为该区块优快钻井提供了技术支持。
    Abstract: Borehole instability often occurs in tuff formation drilling in Block C2 of Myanmar.We analyzed the characteristics and mineral components of the formation systematically.On the basis of the drilling fluid previously used in this area,a strong inhibition and plugging drilling fluid system was developed.Field tests show the performance of the new drilling fluid is for superior to the one previously used.Borehole collapse accidents have been greatly reduced and tripping speed improved significantly.In addition,borehole is more regular and drilling cycle is shortened.The new drilling fluid system can meet the requirements of quick and safe drilling,and borehole instability problems in this area can be solved effectively.
