摘要
本文通过室内研究和现场应用表明,该钻井液润滑效果好、高温高压滤失量低、防塌能力强、抑制性强,能够有效降低井下摩阻,稳定戴南组、阜宁组泥页岩地层,能够很好的满足江苏油田易垮塌井的钻井需要。
The indoor research and onsite application of the drilling fluid with high inhibitive ability and anti-sloughing in Jiangsu Oilfield presented in this article show that it has good performance in lubrication and inhibitive ability and anti-sloughing as well as low in leakoff at high pressure and temperature.It can reduce the down hole friction effectively and keep the shale layer in Dainan and Funing Formation stable,which meet the requirements of drilling operation in collapse wells in Jiangsu Oilfield.
