中文摘要:泥浆是钻探工程的重要组成部分,它在确保安全、优质、快速钻进中起着关键性的作用,被人们称为“钻井的血液”。随着孔深逐渐加深,以往的普通泥浆密度大,流变性差,泥皮厚,已经无法适应岩心钻探的要求。目前主要使用低固相泥浆,通过添加各种化学处理剂来改善泥浆的性能。本文介绍了X-A成膜剂低固相泥浆在老许寨铜矿钻探施工中的实际应用。

Application of drilling mud with X-A film-forming agent in drilling in Laoxuzhai Copper Mine
Abstract:Drilling mud is an important part of drilling engineering. It plays a key role in ensuring safety, quality and rapid drilling, and is called “the blood for drilling”. As the hole depth gradually deepens, the existing drilling mud is unable to meet the requirements of current core drilling due to high density, poor rheological property, and thick mud cake. At present, low solid mud is mainly used, while various chemical treatment agents are added to improve its performance. This paper introduces the application of low solid phase drilling mud with X-A film-forming agent in drilling in LaoXuZhai copper mine.
