Abstract
- A lot of oil drilling wastes are produced during oil drilling work in Bohai offshore oilfield, which mainly contain waste oil drilling mud and waste oil drilling cuttings. The cost of environmental risks, transportation, treatment and disposal are increasing with the growth of development well of offshore oilfield. Therefore, the research of source reduction and resource disposal has been carried out. Negative pressure and micro-vibration filtration system was used to reduce the wastes on vibrating screen and simulation trial has been finished. The process “gel-breaking-centrifugation-ozone flotation-ceramic membrane” was used to treat the waste oil drilling mud and the treated drilling mud could be reused to prepare the fresh oil drilling fluid. The results showed that the waste drilling cuttings had a good dehydration effect, the liquid content of the waste oil drilling cuttings at outlet reached 21%-22%, and the oil content of clean water reused to prepare fresh oil drilling fluid was under 10 mg/L under the conditions that the liquid content was above 100% at inlet, the rotation rate was under 40% and mesh specifications were under API160.
