| 摘 要： | 室内合成的聚胺强水化抑制剂SD-A可有效抑制黏土水化分散,与国外同类产品Ultrahib性能相当。聚胺水基钻井液配方为:4%膨润土浆+3%SD-A+0.5%SD-E+1%PAC-LV+0.3%XC+3%SD-506。与聚合醇、阳离子、KCl/聚合物钻井液相比,二级膨润土在聚胺水基钻井液中的膨胀率最小,岩屑回收率最高,表明聚胺水基钻井液抑制页岩水化分散能力强。聚胺水基钻井液120℃热滚16 h前后的流变性能稳定,热滚后动塑比为1.07,高于油基钻井液。在400 mL聚胺水基钻井液中分别加入144 g NaCl、8 g CaCl2和80 g劣土后,体系流变性发生不同程度的改变,而滤失量变化较小,其中CaCl2对体系流变性影响最大。结果表明聚胺水基钻井液的抗污染能力较强。屈曲硬度实验、耐崩散实验和黏结实验等新型实验方法表明,聚胺水基钻井液的抑制性接近甚至超过油基钻井液,清洁润滑性优良,其EC值为12 g/L,符合环保要求。另外,简要分析了聚胺水基钻井液的抑制机理。

| Abstract: | The hydration and dispersion of clay could be inhibited effectively by a synthesized polyamine strong hydration inhibitor SD-A as foreign product Ultrahib.The formula of polyamine water-based drilling fluid was established: 4% base slurry,3% SD-A,0.5% SD-E,1% PAC-LV,0.3% XC and 3% SD-506.Compared with polymeric alcohol drilling fluid,cation drilling fluid and KCl/polymer drilling fluid,the shale swelling rate was the least for polyamine water-based drilling fluid and the cutting recovery was the highest,ind... |
