Abstract

The utility model relates to an effluent oil and sewage collection and reinjection device which mainly solves the problem that overflow liquor produced by underground gathering and transporting operation pollutes the environment. The effluent oil and sewage collection and reinjection device is characterized in that the inner top of a liquid collecting tank (10) is provided with liquid inlet pipes (16 and 17) which are communicated with an ingress pipe (7) and a suction pipe (15); the other end of the suction pipe (15) is communicated with a liquid collecting plate (6); the other end of the ingress pipe (7) is communicated with a well head; the closed liquid collecting tank (10) is connected with a vortex vacuum pump (1) and a rotor transfer pump (3); and the rotor transfer pump (3) is connected with a reinjection pipe (18). The effluent oil and sewage collection and reinjection device is protective to the environment, reduces the pollution and improves the working condition, and at the same time the effluent oil and the sewage are recycled, so the effluent oil and sewage collection and reinjection device reduces the work amount and the production cost.

Description

Sump oil sewage collecting re-injection device
Technical field
The utility model relates to a kind of production wellhead collection transporting operation overflowing liquid and collects re-injection device, especially sump oil sewage collecting re-injection device.
Background technology
When field produces down-hole collection is failed oil producing operation, because borehole pressure can make well head produce overflow, inevitably produce a large amount of sump oil sewage, common way is to dig pit nearby to bury or repair pollution discharge pond and directly collect, when sump oil sewage reaches a certain amount of, lean on the tank car centralized collection, but collection is not thorough, well head periphery soil compaction when serious, not only increased workload and labour intensity, also caused very big pollution simultaneously to environment.
The utility model content
The technical problems to be solved in the utility model provides a kind of sump oil sewage collecting re-injection device, the overflowing liquid that will produce when the collection transporting operation of down-hole is through being recycled into direct cycling and reutilization in the oil extraction transportation system pipe network again after collecting, purifying, thereby reduce pollution and improve operating condition, reduce labour intensity and cost of production.
The technical solution of the utility model is: a kind of sump oil sewage collecting re-injection device, comprise catch tray, airtight liquid collecting jar, the inner top of described liquid collecting jar has the feed tube that communicates with ingress pipe, suction pipe, and the other end of suction pipe communicates with catch tray, and the other end of ingress pipe communicates with well head; And the closed set flow container connects vortex vacuum pump, rotor delivery pump, rotor delivery pump tube connector re-injection pipe.
Three float liquid level instrument that are connected with electric alarm are installed in the above-mentioned airtight liquid collecting jar, in the airtight liquid collecting jar screen pack are installed, airtight liquid collecting jar is the double-layer heat insulation closed container, in the airtight liquid collecting jar constant temperature automatic heating device is installed.
The beneficial effects of the utility model are: because the utility model employing is to place catch tray at the well head place, in time with the sump oil sewage collecting that overflows in the oil producing operation, when working because of airtight liquid collecting jar is negative pressure state, sump oil sewage enters in the liquid collecting jar by suction pipe and feed tube, and the sump oil sewage in the well head sleeve pipe directly send as the liquid collecting jar by ingress pipe and feed tube under the pressure effect of self.In the liquid collecting jar, after filtering, send back in the oil extraction transportation system pipe network by rotor delivery pump, re-injection pipe again.Simultaneously in irritating three Floating Ball Liquid Level instrument that are connected with electric alarm are installed, control jar interior liquid level and rotor delivery pump opens, stops and the Automatic Cycle program of heating system respectively.The constant temperature automatic heating device also is installed, to guarantee preventing that at low temperature season liquid from freezing and tie cured and guarantee the normal operation of this device in the filling.The utility model is at the protection environment, reduce to pollute and when improving operating condition, because of sump oil sewage in time reclaims and recycling utilizes again, and reduced workload and cost of production.
Description of drawings
Accompanying drawing 1 is the structural representation of sump oil sewage collecting re-injection device.
The middle liquid level instrument of liquid level ball 12-13-goes up liquid level instrument 14-oil extraction transportation system pipe network 15-suction pipe 16-feed tube 17-feed tube 18-re-injection pipe under the airtight liquid collecting jar of the 1-vortex vacuum pump 2-alarm 3-rotor delivery pump 4-scavenging pump 5-automatic heater 6-catch tray 7-ingress pipe 8-desilting valve 9-screen pack 10-11-
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: implementation step is to place catch tray 6 at the well head place, communicates with airtight liquid collecting jar 10 by suction pipe 15, feed tube 17, and well head communicates with airtight liquid collecting jar 10 by ingress pipe 7, feed tube 16; The airtight liquid collecting jar 10 of the other end and vortex vacuum pump 1 and the rotor delivery pump 3 that re-injection pipe 18 is housed are connected.Three the float liquid level instrument (11,12,13) that are connected with electric alarm 2 are installed in the airtight liquid collecting jar 10; Airtight liquid collecting jar 10 is the double-layer heat insulation closed container, in jar screen pack 9 is installed, constant temperature automatic heating system 5 is installed.
During operate as normal, under each valve opening state, vortex vacuum pump 1 work that is connected with airtight liquid collecting jar 10, make in the airtight liquid collecting jar 10 and form negative pressure, liquid in the catch tray 6 on the well head passes through a jar interior conduit 16 with the ingress pipe 7 interior liquid that are connected in well head and airtight liquid collecting filling 10,17 flow in the airtight liquid collecting jar 10 through filter screen 9 from abhiseca automatically, when treating in the middle of liquid level rises to behind the liquid filtering liquid level, middle liquid level instrument 12 starts coupled electric alarm 2, the rotor delivery pump 3 startup work that make jar interior automatic heating device 5 and be connected with filling, the liquid after the purification is through rotor delivery pump 3, re-injection pipe 18 is recycled into oil extraction transportation system pipe network 14; When liquid level was reduced to down liquid level in the airtight liquid collecting filling 10, following liquid level instrument 11 started electric alarms 2, and rotor delivery pump 3 stops operating, and automatic heater 5 disconnects simultaneously; When intermediate liquid position instrument 12 because of accident work when malfunctioning, 3 stalls of rotor delivery pump, liquid level rises to when touching liquid level instrument 13, starts alarm 2 once more, liquid flowing valve is closed in 1 stall of vortex vacuum pump this moment immediately, checks cause of accident.During the same day end of job, scavenging pump 4 work that are connected with rotor delivery pump 3 are with the raffinate emptying in the rotor delivery pump 3.Also to regularly open the desilting valve 8 that a side-lower is irritated in airtight liquid collecting, carry out artificial desilting.The utility model when reducing pollution and improving operating condition, because of sump oil sewage in time reclaims and cycling and reutilization, and has reduced workload and cost of production at the protection environment.
