我国腐植酸资源丰富,对不同来源HAK(KHm)钻井泥浆处处理剂进行应用评价及机理探讨对于生产和理论研究均有重要意义。本文对不同来源的腐植酸钾做为钻井泥浆处理剂进行应用评价。通过成分分析,官能团表征及①KHm对泥浆流变性②KHm的降失水作用③KHm抑制粘土水化膨胀作用的试验得出结结论: 一、不同来源KHm(HA~-%和K~+%相同)均有良好的降失水作用,降粘、降切和抑 The humic acid resources in our country are rich. It is of great significance to both the production and theoretical research to evaluate the application of HAK (KHm) drilling mud treatment agent from different sources and to explore the mechanism. In this paper, different sources of potassium humate as a drilling mud treatment agent for evaluation. Through component analysis, functional group characterization and ① KHm on mud rheology ② KHm loss of water ③KHm inhibition of hydration and swelling of clay experiments concluded: First, different sources of KHm (HA ~ -% and K ~ +% same) are A good loss of water loss, viscosity, cut and suppression
