为了探明钻井废弃物处置场地对其上作物生长的利弊，将长庆油田钻井废弃物回
填法处理后井场生长的谷子和高粱作为研究对象，研究钻井废弃物对谷子和高粱产量、重
金属含量、作物品质和氨基酸的影响。结果表明，钻井废弃物处理场上生长的谷子和高粱
Pb、Cd、Cr、As 和 Hg 等重金属含量处于安全范围内; 与对照相比，钻井废弃物生长谷子和
高粱产量增加明显，谷子产量增加了 585 kg·hm
－2 ，高粱产量增加了 900 kg·hm －2 。与
对照相比，对谷子和高粱品质提升较小钻井废弃物对谷子和高粱必需和非必需氨基酸均
有增加作用，但增加效果不明显。两种作物的必须氨基酸中的赖氨酸含量增加较多，非必
需氨基酸中天冬氨酸和谷氨酸增加较多。因此，本试验中钻井废弃物可以明显的增加作
物产量，对作物氨基酸含量增加较小，重金属未超标，符合安全标准。

To investigate the advantages and disadvantages of drilling wastes to crops growth on wastes dis-
posal sites，the drilling wastes were backfilled in Changqing Oilfield，the millet and sorghum grown on the well
sites were used as the research object to study the effect of the drilling wastes on millet and sorghum yield，heavy
metal content，crop quality and amino acids． The results showed that the content of heavy metals such as Pb，
Cd，Cr，As and Hg in millet and sorghum grown on the drilling wastes disposal sites stayed in a safe range;
Compared with the control，the output of millet and sorghum grown from drilling wastes increased significantly，
the yield of millet increased by 585 kg·hm
－2 ，and the yield of sorghum increased by 900 kg·hm －2 ． Compared
with the control，the quality improvement of millet and sorghum was less． Drilling wastes increased the essential
and non-essential amino acids of millet and sorghum，but it was not obvious． The content of lysine in the essen-
tial amino acids of the two crops increased much，and the aspartic acid and glutamic acid in the non-essential a-
mino acids increased much，too． Therefore，the drilling wastes in this experiment can significantly increase cropyields，but the crop amino acid content increases little，the heavy metals don’t exceed the standard and meet
safety standards．
