Description
Technical field
It the utility model is related to oil equipment technical field, the special oil spilling deposition dehydrating storage tank in specifically a kind of oil field.
Background technology
In oilfield process, each individual well, which produces crude oil and focuses on multi-purpose station, to be handled, due to contain in crude oil compared with
Juicy, and viscosity of crude is higher, and WO emulsion is formed during transport flow and further increases flow resistance, and breast
Shape liquid is stablized non-breakable.Original multi-purpose station crude oil dewatering process flow is two sections of the power-up dehydration of pressure thermo-chemical setting dihydration de-
Water flow-path.But because each block in oil field is scattered, the production capacity and dehydration equipment ability built up are difficult completely supporting, demulsification
Chemicals be limited in scope, the technical merit of managerial skills and operating personnel are limited, dehydration equipment operation it is all abnormal.Dehydration
Afterwards, water content in crude oil, sewage is not up to standard containing gauging, and oil content is sometime up to more than 10% in indivedual website sewage.
In a word, there is not been reported for a kind of special oil spilling deposition dehydrating storage tank in oil field.
The content of the invention
To solve the problems of the prior art, the utility model provides a kind of oil field special oil spilling deposition dehydrating storage tank.
Technical scheme is used by the utility model solves its technical problem：
A kind of special oil spilling deposition dehydrating storage tank in oil field, including tank body, purification oil export pipeline, oil emulsion inlet tube
Line, wet oil inlet line, regulating tank, overflow launder, outlet of sewer pipeline；
Tank body is cylindrical ground tanks, and top is arc tank deck, bottom have side be connected to purification oil export pipeline,
Oil emulsion inlet line, wet oil inlet line；
Oil emulsion is entered in tank body by oil emulsion inlet line；Oil emulsion inlet line and the disk of tank body inside spin coiling
Pipe one connects；Coil pipe one is provided with transversely arranged oil-out, is easy to oil emulsion dispersing and settling；
Purification oil export pipeline connects with the overflow launder at the top of tank body, and overflow launder is the annular groove knot for surrounding inner tank wall
Structure；
Wet oil inlet line enter tank body in, the bottom of coil pipe one be provided with coiled coil coil pipe two, end seal,
Wet oil inlet line is connected with coil pipe two, and coil pipe two is provided with transversely arranged intensive oil-out, is easy to wet oil dispersing and settling；
Another side bottom of tank body is provided with outlet of sewer pipeline, and outlet of sewer pipeline connects up regulation water in tank wall
Case, ground is returned to from regulating tank, discharged.
The beneficial effects of the utility model and advantage are：
1st, the utility model produces static pressure principle using liquid, by cleaned crude oil outlet and outlet of sewer（Regulating tank）If
Different height is counted into, the automatic overflow formed under normal pressure.
2nd, the utility model dehydration temperaturre is relatively low, generally at 35 DEG C or so, it is not necessary to extra heating, saves energy consumption, reduces
Operating cost.
3rd, the utility model dehydrating effect is preferable, and Water in oil is below 0.5%；Oil-containing is in 100ppm or so in water.
4th, the utility model dehydration is longer, typically no less than 24h, and infall process is stable.
5th, the adjustable regulating tank of the utility model design height, can based on crude water content control difference liquid level it is poor, it is real
Now preferable dehydrating effect.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
Fig. 1 further illustrates to the utility model below in conjunction with the accompanying drawings.

2nd, oil emulsion inlet line 3, wet oil inlet line 4；
Oil emulsion is entered in tank body 1 by oil emulsion inlet line 3；Oil emulsion inlet line 3 is coiled with the inside spin of tank body 1
Coil pipe 1 connect；Coil pipe 1 is provided with transversely arranged oil-out, is easy to oil emulsion dispersing and settling；
Purification oil export pipeline 2 connects with the overflow launder at the top of tank body 1, and overflow launder is the annular groove for surrounding the inwall of tank body 1
Structure；
Wet oil inlet line 4 enters in tank body 1, and the coil pipe 29 of coiled coil, end are provided with the bottom of coil pipe 1
Sealing, wet oil inlet line 4 are connected with coil pipe 29, and coil pipe two is provided with transversely arranged intensive oil-out, is easy to aqueous oil
Dissipate sedimentation；
1 another side bottom of tank body is provided with outlet of sewer pipeline 7, and outlet of sewer pipeline 7 connects up regulation in the outer wall of tank body 1
Water tank 5, ground is returned to from regulating tank 5, discharged.
Embodiment
When storage tank works, oil emulsion and wet oil enter in storage tank, and liquid level constantly rises, due to crude oil and the density contrast of water
（Respectively 0.85 and 1.0）, infall process Crude Oil floats to the top of storage tank, and recovered water then sinks down into the bottom of storage tank.Profit
Static pressure principle is produced with liquid, by cleaned crude oil outlet and outlet of sewer（Regulating tank）It is designed to different height.Then purify
Crude oil float up in overflow launder, discharged by purification oil export, the sewage after sedimentation by outlet of sewer drain tank outside, formed normal
The automatic overflow of pressure.
