摘要
通过对正电胶、聚合物、聚磺钻井液特点进行分析 ,在室内实验的基础上 ,设计研究了 MMH聚合物 - MMH聚磺钻井液体系。 2 0口井的现场应用表明 ,与同时期未用该体系的 9口井相比 ,平均钻井周期缩短 2 .92 d,平均井径扩大率从 14 .0 9%下降到 9.97% 。
Based on the laboratory experiments, MMH polymer MMH polysulfonate drilling fluids system is developed through analyzing the properties of positive colloid, polymers and polysulfonate muds. Field applications in twenty wells show that the average drilling cycle is decreased by 2.92 days and the average ratio of hole enlargement is decreased from 14.09% to 9.97% while comparing with other nine wells without MMH polymer MMH polysulfonate drilling fluids system. Its effect is obvious.
