摘要
采用大港油田钻井废弃泥浆作为实验原料,利用改良材料对其进行固化试验,确定了改良材料的配比。结果表明:将固化后的钻井泥浆用作路基底层材料,当改良材料掺量为20%时,最佳含水率为19%,7d强度为2.06MPa,此时水稳定性较高,重金属离子浸出量得到了有效的控制。
The experiment use improved materials to complete the solidify for waste drilling fluid which from the Dagang Oilfield.The ratio of the improved materials was determined.The waste drilling fluid which was solidified is used as the road base layer,the experimental results show that when the ratio of the improved materials is 20%,the best moisture content is 19%,and its 7 d strength is 2.06 MPa.At this time,the water stability is high and the leaching amount of heavy metal ions are controlled effectively.
