摘要
针对含膨润土相加重钻井液易对油气层产生损害，加重密度受到限制，高密度条件下，流变性调整困难等缺点，我们开展了氯化钙加重钻井液的室内研究，并在威东六井的现场进行了初步应用，本文将介绍该体系的室内试验与现场应用情况。
Weighting drilling fluid with bentonite can cause damage to oil and gas formation,so the weighting density is limited.And for high density,it is difficult to adjust rheology.Regarding to these demerits,indoor research of calcium chloride weighting drilling fluid is done,and this paper introduces its field application in Weidong 6 well.
