Abstract
The utility model relates to a collecting and recycling device for overflow liquid of a producing wellhead. The collecting and recycling device mainly solves the problem that overflow liquid generated during underground gathering and transportation operation pollutes environments. The collecting and recycling device comprises a liquid collecting plate and a closed liquid collecting tank, a liquid inlet pipe communicated with a lead-in pipe and a suction pipe is arranged on the inner top of the liquid collecting tank, the other end of the suction pipe is communicated with the liquid collecting plate, the other end of the lead-in pipe is communicated with the wellhead, the closed liquid collecting tank is communicated with a vortex vacuum pump and a rotor conveying pump, and the rotor conveying pipe is connected with a recycling pipe. By the aid of the collecting and recycling device, environments are protected, pollution is reduced, operation conditions are enhanced, the overflow liquid can be timely recycled, and accordingly operation load and production cost are reduced.
Description
Technical field
Produce overflowing liquid when the utility model relates to a kind of production wellhead collection transporting operation and collect the re-injection device.
Background technology
When collection is failed oil producing operation in the field produces down-hole,, inevitably produce a large amount of overflowing liquids because borehole pressure can make well head produce overflow; Common way is to dig pit nearby to bury or repair pollution discharge pond and directly collect; When overflowing liquid 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 problem that the utility model will solve provides a kind of production wellhead overflowing liquid and collects the re-injection device; The overflowing liquid that will when the collection transporting operation of down-hole, produce is through be 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 scheme of the utility model is: a kind of production wellhead overflowing liquid is collected the 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 appearance 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 effect of the utility model is: because the utility model employing is to place catch tray at the well head place; In time the overflowing liquid that overflows in the oil producing operation is collected; When working because of airtight liquid collecting jar is negative pressure state; Overflowing liquid gets in the liquid collecting jar through suction pipe and feed tube, and the overflowing liquid in the well head sleeve pipe directly send like the liquid collecting jar through 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 through rotor delivery pump, re-injection pipe again.Simultaneously in irritating, three Floating Ball Liquid Level appearance 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 overflowing liquid in time reclaims and recycling utilizes again, and reduced workload and cost of production.

The specific embodiment
Be described further this use is novel below in conjunction with accompanying drawing:
By shown in Figure 1, this production wellhead overflowing liquid is collected the re-injection device, comprises catch tray 6; Airtight liquid collecting jar 10; Wherein, the inner top of liquid collecting jar 10 has the feed tube (16,17) that communicates with ingress pipe 7, suction pipe 15; And the other end of suction pipe 15 communicates with catch tray 6, and the other end of ingress pipe 7 communicates with well head; And airtight liquid collecting jar 10 connects vortex vacuum pump 1, rotor delivery pump 3, rotor delivery pump 3 tube connector re-injection pipes 18.
In addition, three the float liquid level appearance (11,12,13) that are connected with electric alarm 2 are installed in the airtight liquid collecting jar 10;
In the airtight liquid collecting jar 10 screen pack 9 is installed, and airtight liquid collecting jar 10 is double-layer heat insulation closed container and constant temperature automatic heating device 5.
Implementation step is to place catch tray 6 at the well head place, communicates with airtight liquid collecting jar 10 through suction pipe 15, feed tube 17, and well head communicates with airtight liquid collecting jar 10 through 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 of annotating return pipe 18 is housed is connected.Three the float liquid level appearance (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; The vortex vacuum pump 1 that is connected with airtight liquid collecting jar 10 is worked, and makes the airtight liquid collecting jar 10 interior negative pressure that form, and the liquid in the catch tray 6 on the well head flows in the airtight liquid collecting jar 10 through screen pack 9 from abhiseca through jar interior conduit 16,17 with the ingress pipe that is connected in well head and airtight liquid collecting filling 10 7 interior liquid automatically; When treating in the middle of liquid level rises to behind the liquid filtering liquid level; Middle liquid level appearance 12 starts the coupled electric alarm that connects 2, the rotor delivery pump 3 startup work that make jar interior automatic heating device 5 and be connected with filling, and the liquid after the purification is recycled into oil extraction transportation system pipe network 14 through rotor delivery pump 3, re-injection pipe 18; When liquid level was reduced to down liquid level in the airtight liquid collecting filling 10, following liquid level appearance 11 started electric alarms 2, and rotor delivery pump 3 stops operating, and automatic heater 5 breaks off simultaneously; When intermediate liquid position appearance 12 because of accident work when malfunctioning, 3 stalls of rotor delivery pump, liquid level rises to when touching liquid level appearance 13, starts alarm 2 once more, liquid flowing valve is closed in 1 stall of vortex vacuum pump this moment immediately, the inspection 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 overflowing liquid in time reclaims and cycling and reutilization, and has reduced workload and cost of production at the protection environment.
