Description
technical field:
The utility model relates to the implement in a kind of petroleum drilling and mining process, is specifically related to a kind of twin-stage desanding treater of sand-washing fluid.
background technology:
Each elephant of China enters the exploitation middle and later periods in succession, sand production has become serious problem, directly have influence on the crude output of oil well, therefore oil field adopts desanding treater of sand-washing fluid mostly, but the desanding efficiency of the desanding device of existing process car is low, use through simple precipitation Posterior circle, the fine silt in liquid can be refilled in well again, thus reduces operating efficiency.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and a kind of twin-stage desanding treater of sand-washing fluid is provided, it is easy to use, simple to operate, and thoroughly can remove the silt particle in sand washing returning fluid, sand cleaning fluid can be recycled, be easy to large-scale promotion application.
In order to solve the problem existing for background technology, the utility model adopts following technical scheme: be made up of the desanding system on car body and car body, and desanding system comprises desanding district, long-pending sand launder and decanting zone; Desanding district is provided with returning fluid's entrance, and the pipeline of returning fluid's entrance is equipped with three-way diverter valve, and what be connected with returning fluid entrance by pipeline is hydrocyclone; Long-pending sand launder is built with interconnective force-increasing mechanism and spiral conveying blade, and force-increasing mechanism and spiral conveying blade are controlled by the handwheel amassed outside sand launder; Decanting zone is divided into gravitation settler, oil trap and upper flume three regions by dividing plate.
Described hydrocyclone sidewall has inlet, and there is liquid outlet on top, and there is sand removing hole lower end; The built-in cyclone separator of hydrocyclone, cyclone separator is located at below liquid outlet, is in same level line with inlet.
The liquid outlet on described hydrocyclone top is communicated with gravitation settler by bleed off pipe.
Described dividing plate is undaform.
The utility model structure is simple, easy to operate, adopts the multistage desanding of hydrocyclone, the efficiency of desanding is high, thus improves oil recovery rate, and sand cleaning fluid also can be made to work continuously, the disposal respectively of oil-sand water, has saved great lot of water resources, achieves green operation and cleaner production.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is hydrocyclone front view.
Fig. 3 is hydrocyclone top view.
detailed description of the invention:
With reference to Fig. 1, the utility model specifically adopts following embodiment: a kind of twin-stage desanding treater of sand-washing fluid, is made up of the desanding system on car body 19 and car body 19, and desanding system comprises desanding district 15, long-pending sand launder 12 and decanting zone 13; Desanding district 15 is provided with returning fluid's entrance 7, the pipeline of returning fluid's entrance 7 is equipped with three-way diverter valve 8, and what be connected with returning fluid entrance 7 by pipeline is hydrocyclone 9; Long-pending sand launder 12 is built with interconnective force-increasing mechanism 5 and spiral conveying blade 6, and force-increasing mechanism 5 and spiral conveying blade 6 are controlled by the handwheel 4 outside long-pending sand launder 12; Decanting zone 13 is divided into gravitation settler 1, oil trap 2 and upper flume 3 three regions by dividing plate 14.Described hydrocyclone 9 sidewall has inlet 16, and there is liquid outlet 17 on top, and there is sand removing hole 11 lower end; The built-in cyclone separator 18 of hydrocyclone 9, cyclone separator 18 is located at below liquid outlet 17, is in same level line with inlet 16.The liquid outlet 17 on described hydrocyclone 9 top is communicated with gravitation settler 1 by bleed off pipe 10.Described dividing plate 14 is undaform, and the dividing plate 14 of undaform can play and hinder profit flowing in each region, increases the time of staying, is convenient to the effect that greasy dirt gathers.
What this device adopted is hydrocyclone 9, it is the principle utilizing centrifugal sedimentation and density contrast, when returning fluid under pressure, hydrocyclone 9 is entered by returning fluid's entrance 7, the cyclone separator 18 impacted in hydrocyclone 9 produces rotary motion, sand particle is larger, suffered centrifugal force is larger, be easy to be thrown toward wall, be rotated in the sand of cyclone separator 18 outer ring, radius is large, rotary speed is fast, suffered centrifugal force is also large, also easily wall is thrown toward, after sand is thrown toward wall, because Action of Gravity Field sinks, discharging from sand removing hole 11 flows in long-pending sand launder 12, handwheel 4 outside long-pending sand launder 12 drives force-increasing mechanism 5, force-increasing mechanism 5 drives spiral conveying blade 6 to be transported to outside device by sand grains, be convenient to unified collection process, core compared with the liquid cleaned because pressure is little, speed is high and become rising eddy flow by liquid outlet 17 and flow out through bleed off pipe 10 to gravitation settler 1, natural subsidence, silt particle remaining in further removing liquid, liquid after sedimentation enters oil trap 2 above the dividing plate 14 of gravitation settler 1, on crude oil is bubbled through the water column because density is little, the large water of density, then by flowing in upper flume 3 below the dividing plate 14 of oil trap 2, recycles.
This device is in order to better thoroughly remove the silt particle in sand cleaning fluid, and have employed Multi-stage spiral and be separated, the first order carries out desanding by the hydrocyclone 9 that bore is large, and the second level by two small-bore hydrocyclone desanding in parallel, reaches better desanding effect again.
This device additionally uses three-way diverter valve 8, and it both can start in sand washing the crude oil that relief returns out and enter petroleum pipeline, sand washing can be allowed again to terminate rear unnecessary sand cleaning fluid and also to be entered the station process by petroleum pipeline.
This apparatus structure is simple, easy to operate, take full advantage of physical knowledge, adopt multistage desanding, except sand coarse aggregate ratio improves, oil recovery rate also and then improves, and sand cleaning fluid also can be made to recycle, and not only saves sand cleaning fluid and haulage vehicle expense, improve operation quality, extending the production cycle of oil well, and saved a large amount of water resources, bringing huge economic benefit for reclaiming crude oil industry.
