多功能复合剂在伊塘湖矿区ZK11-1孔的应用

Application of Multifunctional Complex Additive in ZK11-1 Hole of Yitanghu Mine

摘要:

多功能复合剂是一种针对复杂地层钻探研发的新型膨润土有机改性钻井液复合材料。通过敦煌伊塘湖钾镁盐矿区ZK11-1孔的成功应用，证明其具有高效护壁作用，抗盐侵污染能力强，用其配制饱和盐水钻井液可适用于岩盐、钾石盐、光卤石等盐膏地层钻进。

Abstract:

Multifunctional complex additive is a new drilling composite material of organically modified bentonite developed for drilling in the complex formation. The successful application of multifunctional complex additive in Yitanghu district ZK11-1 hole of Dunhuang indicates that it has effective wall protection and anti-pollution ability, with which the saturated brine drilling fluid prepared can be used for drilling in salt-gypsum stratum such as rock salt, sylvite and carnallite.
