| 摘 要： | 对江苏油田富９７、曹４２和余１８井的废弃水基（含混油）钻井液进行了化学脱稳和固液分离处理。不同的钻井液脱稳后，用离心分离法脱水率范围为２５％－５２％，其泥饼含水率为４８％－３３％；用压滤法分离脱水率范围为３５％－６０％，其泥饼含水率为５９％－４５％。钻井液离心脱水的处理费用仅为４－１１．５元／ｍ＾３。

| Abstract: | An experimental study on chemical destabi-lization and solid-liquid seperation of three water-based(inclined oil-emulsion) waste drilling fluids from Jiangsuoilfield is conducted using coagulants and nocculants. Thedehydration rate is 26% ~ 52% and it's weter-in-mudcakeratio 48% ~ 33% by the method of centrifugal dehydra:tion; 35% ~ 60% and 59% ~45% by the press filter de-hydration. The treatment costs of waste drilling fiuid oulyis RMB 4.0 ~11. 5 yuan/m3 |
