摘要
采用测定粘附系数和页岩抑制率的方法研究了聚合醇在浊点前后对钻井液润滑性和抑制性的影响,探讨了 其作用机理。研究结果表明,温度高于浊点时聚合醇钻井液的润滑性明显好于温度低于浊点时的润滑性,抑制性与浊点 关系不大,在高温时抑制效果更好。
This paper studies affects of polyalcohol turbidity point on lubrication and inhibition of drilling fluids, discusses its mechanisms by measuring attachment coefficient and shale inhibition. Research results show that lubrication of polyalcohol mud is much better when the temperature is higher than its turbidity point than under the other conditions, and its inhibition is not remarkable affected by turbidity, and it is better under higher temperature.
