利用热化学─搅拌水洗─重力沉降的工艺方法，可以使含油泥砂处理后达到环保要求。试验确定了最佳的除油化学剂，最佳的处理工艺参数。结果表明，该处理工艺完全适用于含油泥砂的除油，对油田生产以及环境保护都有重要意义。
The use of thermochemistry ─ stirring washing ─ gravity sedimentation process, oil sludge can be processed to meet the environmental requirements. The test determines the best degreasing chemicals, the best processing parameters. The results show that the treatment process is completely suitable for oil removal of oil and sand, oil production and environmental protection are of great significance.
