Research progress on resource utilization and harmless treatment of
Keywords: Oily sludge, Harmless treatment, Resources utilization. 1. Introduction. With the enhancement of China's industrial strength, oil has been extensively exploited and used. In 2018, China's consumption of oil reached 620 million tons, and the resulting oily sludge exceeds 5 million tons annually [1]. These oily sludge have a huge output
Currently in China, approximately 88% of oil-bearing sludge is treated using mechanical separation techniques along with thermochemical purification processes, the mechanical separation process alone accounts for the treatment of 25.28% of the total volume of oily sludge processed while these two treatments also exhibit the highest rates of crude oil recovery in practical field applications.
Harmless and efficient treatment of oily drilling cuttings
The harmless degreasing formula for oily drilling cuttings was developed based on the efficient degreasing agent CYJ-1. The harmless degreasing formula was biodegradable and efficient, with the oil removal rate of 93.02%, it demonstrated a relatively good oil removal performance.
The Composition of waste oil-in-water drilling fluid from well NP361 in JiDong oilfield was analyzed, water content was 51.83%; oil content was 38.14%; sludge content was 10.03%, high oil content gives a value to be recycled. Physical-chemical collaboration demulsification technology was used for treatment of waste oil-in-water drilling fluid.
Study on the Formation Mechanism and Harmless Treatment Technology of
In the separation process of oil dehydration and wastewater deoiling, a very stable and viscous colloid layer is formed on the oil-water interface, which is high in viscosity and water content, and also contains more oil ingredient, which is difficult to deal with and achieve dehydration. As a result the work of equipment is greatly affected.
The rate of oil recovery is greater than 90%, and the quality of the recycled oil is very good and meets the requirements for No. 10 diesel for cars according to GB/T 19147-2003. The concentrations of oil, chemical oxygen demand (COD), and heavy metals in liquid of the processed mud are lower than the secondary standard number in GB8978-1996.

Erlian Filiale of Hua Bei Oilfield Company, He Bei, 062550, China. [email protected], b [email protected], c [email protected]. Abstract. with the continuous expansion of shale gas development in drilling engineering, there are more and more waste oil drilling cuttings, which has become a heavy burden on the oilfield.
Based on the analysis of the physicochemical properties of oil sludge, this article elaborates on the application scope, advantages and disadvantages of methods such as biodegradation, solidification treatment, mechanical centrifugation, solvent extraction, and pyrolysis from two aspects: harmless treatment and resource utilization of oil sludge.
Achieving Practical Venue Recycle of Waste Oil-Based Drilling Fluids
far-reaching significancefor oil and gas extraction to study the harmless disposal technology of waste oil-based drilling fluids and reuse them under the condition of retaining active ingredients. In the past few decades, several treatment methods for waste oil-based drilling fluidshave been developed, such as thermal
The results showed that the quality of the treated wastewater was good, the COD decreased from 993 to 89 mg/L, and the oil content decreased from 21,800 to 3.6 mg/L; therefore, the treated water could meet the first-class standard for China’s “The National Integrated Wastewater Discharge Standard” (GB 8978–1996) to achieve resource recovery and the harmless treatment of oil-in-water
