摘要
魔芋与田菁无粘土钻井液是一类分别采用魔芋与田菁植物胶配制而成的新型钻井液,特别适用于金刚石钻进、各种井底动力钻具钻进、水文水井钻进与浅油井钻进,具有保护孔壁,提高钻速、钻头寿命,提高破碎岩矿层采心率,降低泵压,减少激动压力,减少对地层损害等许多优良性能。介绍与讨论了钻井液配方与配制方法、性能分析和比较以及生产应用等。
MY & TG non-clay drilling fluids are a new kind of dtilling fluids prepared respectively withAmorphophallus Konjaku & Sesbania vegetable gum. They are especially suitable for diamonddrilling, drilling for all kinds of downhole motor, hydrogeological well & water well drilling andshallow oil well drilling. They possess many excellent properties for protecting hole wall, raisingdrilling rate, increasing drill bit life, raising core recovery of rock & ore bed in broken formation,reducing the pumping pressure, lowering the surge & swab pressure and reducing damage on theformation. Precription of drilling fluids and preparation methods, analyses & comparison of pro-perties of drilling fluids, production application, etc. are described and discussed in this paper.
