Description

A kind of oil-contained drilling cuttings is with brill processing method
Technical field
The present invention relates to oil and gas well drilling field, particularly a kind of oil-contained drilling cuttings processing method.
Background technology
Background technology
Oil-base mud drilling well, in the construction of Holes of Complicated Wells or horizontal well, has certain advantage, but can produce the solid waste such as discarded slurry and oil-contained drilling cuttings in its use procedure.In the oil-base mud that current China adopts, oil-base mud for base oil, adds various Oilfield Chemicals and barite etc. with diesel oil, white oil etc.According to Chinese Ministry of Environmental Protection's " danger wastes register " regulation, the oil-containing drill waste in oilfield exploitation procedure is demarcated as danger wastes.Part mud simultaneously in discarded oil-base mud and the base oil being adsorbed on solid phase surface are important resources, can recycle.
Use and be in oil base oil-contained drilling cuttings in research at present and discarded oil base mud conditioning technology mainly comprises microbial metabolism edman degradation Edman, hot fractionating process, pyrolysismethod, burning method, organic solvent ablution etc.Microbial metabolism edman degradation Edman is based on centrifugation, Gu utilize the density contrast of oil-two-phase to realize being separated, low oil-containing solid phase after separation utilizes the metabolism of microorganism to decompose oily substance, but needs suitable growth conditions and other nutrient media, and the metabolic cycle of microorganism is usually longer; Bacteria metabolism is by petroleum substance metabolic breakdown, is simple treatment and disposal process, is unfavorable for that base oily substance Resource recoveryization utilizes.Hot fractionating process utilizes relative volatility differential separation, and separation temperature is high, and energy consumption is high.Pyrolysismethod utilizes anoxybiotic pyrolysis to be separated, and ensure that anoxybiotic is heated to 500-1000 DEG C, and equipment investment is large, and power consumption is large, and during high-temperature process, condensation coking can occur heavy hydrocarbon, and oil loss is large, and after process, residue oil content is higher.Burning method, by itself and fuel are coordinated burning, realize the removal that oil-base mud pollutes, but its processing cost is higher, likely brings secondary pollution simultaneously.Organic solvent ablution utilizes extraction principle, by the base oil class extracting substances in solid phase out, then by heating Distillation recovery organic solvent, but in operable organic solvent, major part all has certain toxicity, also there is the possibility of blast when organic vapor concentration is higher.Meanwhile, Oilfield Development Engineering, some oil wells is distant, adopts car roping to central treating station process, and the rear mud of process is transported again well site back and recycled, and cost of transportation is higher.On-the-spot a kind of oil-contained drilling cuttings of research and development of being badly in need of is with brill treating apparatus and method.
