Description
Technical field
The present invention relates to a kind of water treatment device, especially a kind of oil field flushing waste disposal plant.
Background technology
For a long time, when Oil/gas Well clean-out service, with swiftly flowing liquid, silt particle is stopped up in shaft bottom and break up, and use the carrying capacity of returning in the circulation of liquid stream, the silt particle breaking up is taken out of to ground and effectively prevented silt blocking hydrocarbon zone, guarantee Oil/gas Well stable yields.When clean-out service return well liquid band sand oil-containing, turbidity is very high, the each well difference of duration of well flushing, several hours at least, at most more than ten hour.Because the each well in oil field disperses, often wash a bite well and must organize many tank cars to draw in clean water, pull out and return well liquid.Sometimes because waterhead area is far away, can affect the continuity of clean-out service.The situ purification processing problem of returning for a long time well liquid when clean-out service never has reliable treatment facility and goes to solve, and returns well liquid although once adopt sand setting oil removing settling pond to go to process, and, poor filtration effect undesirable owing to separating fails to realize.To sum up, the impact that existing well-flushing pattern produces oil well operation is as follows: cause the waste of water resources; Produce a large amount of tank car roping expenses; Suspended solid and oleaginousness exceed standard, and stratum is polluted; Increase labour intensity, not only time-consuming but also wasting manpower and material resources; If because burst reason causes vehicle roping in time, sand body sedimentation, probably causes work accident.
