通过浊点和岩屑回收率测定,研究了聚乙二醇在几种无机盐水溶液中对岩屑的抑制作用。在NaCl、CaCl2水溶液中,只有在浊点以上聚乙二醇才具有良好的抑制作用;而在KCl水溶液中,聚乙二醇在任何情况下都具有良好的抑制作用。这说明聚乙二醇和氯化钾有协同作用。
Through the determination of cloud point and cuttings recovery, the inhibitory effect of polyethylene glycol on cuttings in several inorganic salt solutions was studied. In NaCl, CaCl2 aqueous solution, only polyethylene glycol above the cloud point has a good inhibitory effect; and in KCl aqueous solution, polyethylene glycol has a good inhibitory effect in any case. This shows that polyethylene glycol and potassium chloride have a synergistic effect.
