摘要
本文对甲酸钠和甲酸钾与常用无机盐NaCl、KCl、CaO进行了抑制性对比评价 ,认为甲酸钾是一种较强的钻井液用抑制性处理剂 ,并对其抑制性作用特点作了简要分析。
The inhibitory property of potassium and sodium formates is studied against common organic salts (NaCl, KCl and CaO) through measuring d(001) of montmorillonite and illite in two reservoir core samples from Xinjiang Oil Fields in different experimental swelling/inhibiting procedures and by using CST and recovery after rolling experiments. The advantages of potassium formate over other chemicals as shale inhibitor are observed in all the experiments performed. The functioning of HCOOK is analysed.
