Description
Technical field
The utility model relates to oilfield, and a kind of Injection Well overflows back dispensing device specifically.
Background technology
Oil field is when well logging, well testing, and well head can produce overflow, and the liquid of current overflow all adopts open recovery, by the fluid storage of spilling in container, then is transported to water treatment plant with oil truck, is used as sewage and processes, cause waste.This open retracting device volume is large, organic efficiency is low, the activity duration is long, contaminated environment, and thoroughly can not solve after head valve is closed and retain leaked liquid in working pipe.
Summary of the invention
In order to overcome, existing oil field shaft mouth overflow recovery device volume is large, organic efficiency is low, the deficiency of contaminated environment, the utility model provides a kind of Injection Well to overflow back dispensing device, it is little that this Injection Well overflows back dispensing device floor space, and reclaim thorough, pollution-free, organic efficiency is high.
The technical solution of the utility model is: a kind of Injection Well overflows back dispensing device, comprise feed liquor pipeline, high-pressure vacuum pump, described feed liquor pipeline is connected with flow control valve, flow control valve outlet connects grade one filter, grade one filter outlet is connected with high-pressure vacuum pump, high pressure vacuum pump discharge connects filtration surge tank, and the outlet of filtering surge tank connects high pressure re-injection pump, and high pressure re-injection pump discharge is connected with outlet line by valve A, valve B successively; Described feed liquor pipeline is also connected with valve B by retaining liquids recovery valve.
The utility model has following beneficial effect: owing to taking such scheme, this device is connected on shaft mouth operation pipe, made to produce negative pressure in working pipe by the swabbing action of high-pressure vacuum pump, the liquid of overflow in working pipe is injected into filter in surge tank, then is recycled in well in operation by high pressure re-injection pump.This pair of pressure reduction overflows back dispensing device at the scene in operation, and overflow line is that airtight negative pressure is run, and reclaims thoroughly, makes that operation field high-altitude no liquid falls, construction plant no liquid, achieves no pollution operation; And overflow recovery and liquid re-injection are synchronously carried out, and shorten the activity duration, avoid waste; This device volume is little, and floor space is little, 1/10th of not enough existing recovery, and according to the number of spillway discharge, automatically can control re-injection amount, efficiency is high.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1-flow control valve in figure, 2-grade one filter, 3-one way valve, 4-high-pressure vacuum pump, 5-relief valve, 6-retains liquids recovery valve, and 7-filters surge tank, 8-high pressure re-injection pump, 9-valve A, 10-valve B, 11-outlet line, 12-feed liquor pipeline.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of Injection Well overflows back dispensing device, comprises feed liquor pipeline 12, high-pressure vacuum pump 4, and described feed liquor pipeline 12 is connected with flow control valve 1, and feed liquor pipeline 12 can adopt two parallel connections, and pipeline is provided with one way valve.Flow control valve 1 exports and connects grade one filter 2, can filter the liquid in pipeline; Grade one filter 2 exports and is connected with high-pressure vacuum pump 4 by one way valve 3; high-pressure vacuum pump 4 exports to connect filters surge tank 7; and high-pressure vacuum pump 4 pipeline is connected with relief valve 5; when high-pressure vacuum pump 4 is out of order; liquid in pipeline directly enters by relief valve 5 and filters surge tank 7, plays the protective effect to high-pressure vacuum pump 4.Described filtration surge tank 7 inside is provided with steam-water separator, and filter surge tank 7 top and be provided with outlet valve, side is connected with safety valve.The outlet of filtering surge tank 7 connects high pressure re-injection pump 8, and high pressure re-injection pump 24 is exported and is connected with outlet line 11 by valve A9, valve B10 successively, and outlet line 11 can connect well head re-injection short circuit.Described feed liquor pipeline 12 is also connected with valve B10 by retaining liquids recovery valve 6, namely feed liquor pipeline 12 is provided with a tee junction, on tee junction respectively by pipeline and flow control valve 1 with retain liquids recovery valve 6 and be connected, the other end retaining liquids recovery valve 6 is connected with valve B10.
When well logging, well testing operation, logging instrument cable is allowed to transfer to the operations such as each depth test parameter of down-hole of a few km, when opening well logging valve, the liquid of down-hole is under the pressure effect of 10-30 Mpa, upwards flowing can be full of working pipe, and upwards overflow along the gap between seal at different levels and operation cable.Now, open high-pressure vacuum pump 4, under the swabbing action of high-pressure vacuum pump 4, the liquid of overflow is sucked into feed liquor pipeline 12, enter into grade one filter 2 through flow control valve 1 to filter, liquid after filtration enters into through high-pressure vacuum pump 4 and filters surge tank 7, then by high pressure re-injection pump 8 by liquid through valve A9, valve B10, and to be recycled in well through re-injection short circuit.In the process, due to the effect of high-pressure vacuum pump 20, in working pipe, produce negative pressure, the liquid in it can be flowed away fast, avoid being taken to top and contaminated environment by operation cable.
After the end of job, close well logging valve and valve A9, open the admission valve retained on liquids recovery valve 6 and re-injection short circuit, under the swabbing action of high-pressure vacuum pump 4, liquid in working pipe can fall to entering into re-injection short circuit under negative pressure and Action of Gravity Field, liquid is outwards flowed out by outlet line 11, successively by valve B10, retain liquids recovery valve 6, flow control valve 1, grade one filter 2 enter high-pressure vacuum pump 4, enter into filtration surge tank 7 again to reclaim, when lower subjob, be re-introduced in well in operation.
