改性腐植酸与钻井液滤失量的关系

Relationship Between Modified KHm and Losing Quantity of Drilling Liquid During Filtering

对同一品位制得的改性腐植酸钾，采用试验方法测定了改性腐植酸钾与钻井液的滤失量的关系，探讨了由于使其改性的基团不同，对其性能的影响程度不同，得出了钻井液滤失量的多少与使之腐植酸钾改性的基团有关．

The title relationship are measured by experimental study in the light of the humic acid obtained by the same raw material. It is put forward that the different property of KHm is due to the different functional group leading to its modification. The losing quantity of drilling liquid during filtering relates to the functional group.
