| 中文摘要:青海省冷湖镇钾矿资源调查评价项目要求对冷湖镇地区开展钾矿资源调查评价。青海省冷湖镇地区地层中含有大段石盐和石膏层，而且地层松散、压力系数大。针对该地区的特殊情况，研制了不分散抗盐防塌冲洗液。应用表明，该冲洗液具备较好的抗盐抗钙能力、防塌性和悬浮性，并且应根据地层压力系数不同来调节冲洗液的密度。 |

| Abstract:An investigation and evaluation on potassium mineral resources in Lenghuzhen of Qinghai Province is required by the project. There are large segments of halite and gypsum layer in the formation of Lenghu Town in Qinghai Province with loose stratum and high pressure coefficients. According to the special circumstances in this region, an salt resistance and collapse control non-dispersible flushing fluid was developed. The application shows that this flushing fluid has good salt and calcium tolerance, anti-sloughing and suspension property. The density of the flushing fluid should be adjusted according to the different formation pressure coefficients. |
