摘要
研制了油基钻井液井筒清洗液,并将其应用于现场。结果表明,该清洗液对井筒上的油膜有较好的清洗效果,清洗率达90%以上,具有较好的储层保护性能。
A novel kind of casing cleaning fluid for oil-based drilling fluid was prepared,and was applied to field test.The results showed that this casing cleaning fluid had good efficiency of cleaning oil film formed on the face of casing pipe.The cleaning rate reached up to 90% with good protection performance to reservoir.
