Description
Technical field
The invention belongs to Treatment Techniques of Extracted Water from Crude Oil Production field, and in particular to a kind of hyposmosis high water cut oil field level difference type collection
Oil collection hydraulic art.
Background technology
Northern Shensi and Gansu Province special oil field layout of east area portion and present situation, at present, when without collection transmission pipe network or well yield compared with
Low do not reach minimum when playing throughput rate, existing flow process is by all liquid measures in well site（Oil and water）By the way of automobile roping
The drawing petrol station that delivers to together nearby is delivered to multi-purpose station after processing again, so, virtually increased roping expense, particularly in oil
Field moisture content is larger（More than 80%）In the case of, automobile roping medium is essentially oil-polluted water, increased subsequent treatment load.
Content of the invention
The purpose of the present invention is to overcome profit roping together in well site in prior art, and operation cost is high and subsequent treatment is difficult
Problem.
For this purpose, the invention provides a kind of hyposmosis high water cut oil field level difference type oil-collecting collection hydraulic art, comprises the steps：
1) oil-collecting：Fuel-displaced to single well preliminary sedimentation is carried out using sump oil case, by the top wet oil after through preliminary sedimentation
Outer defeated after being drawn to multi-purpose station purified treatment nearby using Handling device.
2) catchment：By individual well through preliminary sedimentation after bottom oil-polluted water enter lower water box, then by lower water box
Oil-polluted water enters collection water station by pipeline connection gravity flow of catchmenting.
3) produced water treatment and re-injection：The oil-polluted water unification collected in collection water station is sent into re-injection station through water supply line,
Oil-polluted water returns individual well re-injection by re-injection pipeline after treatment.
Above-mentioned collection water station be arranged on 3-5 seat individual wells catchment pipeline concentrate where.
Above-mentioned re-injection station is arranged on oily district center position.
2) in water collecting process, the oil-polluted water in lower water box can not flow automatically and enter Cai Yong the increasing of collection water station above-mentioned steps
Pressure device delivers to collection water station by the pipeline that catchments after being pressurized temporarily again.
Above-mentioned pressurizer is skid-mounted pressurizer.
The material of the above-mentioned pipeline that catchments adopts mesolow fiberglass.
Above-mentioned re-injection pipeline adopts laying in one ditch with the pipeline that catchments.
Beneficial effects of the present invention：
(1) solve the problems, such as without profit during collection transmission pipe network together roping, this technique avoids profit, and roping is asked together
Topic, the oil after process are pulled away, and water collects defeated nearby, processes nearby and re-injection, saves operation cost in a large number.
(2) solve built facility and recycle problem, to greatest extent using built facility, it is ensured that in well site existing facility is not
Remove, sump oil case, lower water box including well site etc. are cost-effective.
(3) solve the problems, such as that wet oil is aqueous higher, roping again after preliminary sedimentation in well site so that enter joint
The wet oil moisture control that stands significantly reduces subsequent treatment load below 25%.
The present invention is described in further details below with reference to accompanying drawing.

Specific embodiment
Embodiment 1：
In order to overcome profit roping together in well site in prior art, the problem that operation cost is high and subsequent treatment is difficult, this
Embodiment provides a kind of hyposmosis high water cut oil field level difference type oil-collecting collection hydraulic art as shown in Figure 1, comprises the steps：
1) oil-collecting：Fuel-displaced to single well preliminary sedimentation is carried out using sump oil case 1, by the top wet oil after through preliminary sedimentation
Using outer defeated after 3 roping of Handling device to 4 purified treatment of multi-purpose station nearby.
2) catchment：By individual well through preliminary sedimentation after bottom oil-polluted water enter lower water box, then by lower water box
Oil-polluted water enters collection water station 5 by the connection gravity flow of pipeline 2 of catchmenting.
3) produced water treatment and re-injection：The oil-polluted water unification collected in collection water station 5 is sent into re-injection station through water supply line 6
7, oil-polluted water returns individual well re-injection by re-injection pipeline 9 after treatment.
In the present embodiment, oil well produced oil carries out preliminary sedimentation through sump oil case 1, the simply top of 3 roping of Handling device
Wet oil so that enter the wet oil moisture control of multi-purpose station 4 below 25%, significantly reduce subsequent treatment load；And under
The oil-polluted water in portion collects defeated nearby, processes nearby and re-injection, saves operation cost in a large number.
In addition, in the case of oil mass very little, crude oil transmission does not reach minimum throughput rate, crude oil dehydration is utilized in well site
The sump oil case that builds, carries out oil-water separation after being transformed, separately and exclusively do not build dehydration device.
Present invention process is to greatest extent using built facility, it is ensured that in well site, existing facility is not removed, including the dirt in well site
Fuel tank 1, lower water box etc., cost-effective.
Embodiment 2：
On the basis of embodiment 1, collecting system makes full use of topographical elevation difference, and the collection water station 5 is arranged on 3-5 seat individual wells
Where the pipeline 2 that catchments is concentrated, from unlike conventional oil-collecting technique, according to the characteristics of oily area's High water cut, water heavy wool is few, if
Catchment pipeline and station is put, rather than gathering line and station are set；The re-injection station 7 is arranged on oily district center position.
In above-mentioned steps 2）In water collecting process, the relatively low well site of remote individually and physical features, the oil-polluted water in lower water box
Can not be flow automatically entrance collection water station 5, can deliver to collection water station by the pipeline 2 that catchments again after adopting 8 interim supercharging of pressurizer, and described
Pressurizer 8 is skid-mounted pressurizer (including water tank, booster pump and control system).
In addition, in order to meet production engineering specifications, the material of the pipeline 2 that catchments adopts mesolow fiberglass.Described time
Note pipeline 9 adopts laying in one ditch with the pipeline 2 that catchments.
Exemplified as above is only to illustration of the invention, does not constitute the restriction to protection scope of the present invention, all
It is that design same or analogous with the present invention is belonged within protection scope of the present invention.
