Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in accompanying drawing 1 and Fig. 2, this water filling secondary pollution Simulation evaluation test unit, comprise pilot system and medicine system, wherein, described pilot system is provided with two groups of test units, two test units are connected with waterflood pump advancing water main line 1 by same safety valve 2, and the another port of described safety valve 2 connects successively lift pump 4, import sample valve 5, flowmeter 6, inlet pressure gauge 11 by two branch valve and is connected with test tank 7; Described medicine system is that two juxtaposed grug feeding jars 9 are all connected with two dosing pumps 10 by combination valve group, each dosing pump 10 is connected with above-mentioned test tank 7 tops respectively by bypass valve, and the lower end of test tank 7 is provided with delivery gauge 24, and be connected with waterflood pump advancing water main line 1 by outlet valve 25 and reflux pipeline 8.
As preferably, above-mentioned medicine system also comprises the clear water import 12 being connected with combination valve group, standby dosing import 13 and stand-by pump 14.
The tank deck of above-mentioned test tank 7 is provided with air release 15, and tank skin is provided with and adheres to bacterium probe 23 and form 18, pushes up fixedly film hangers 16 in tank, on described film hangers 16, hangs corrosion coupon 17; In tank, place the anti-corrosion Ball-type packing 22 in imporosity of different size, as glass bead, at the bottom of tank, be provided with outlet sample valve 19 and exhaust-valve 20; In addition, in tank, the end, is also provided with and supports screen 21.
In such scheme, the front end of test tank 7 is provided with sample tap 3 or import sample valve 5, inlet pressure gauge 11 and air release 15, and the rear end of test tank 7 is provided with outlet sample valve 19, exhaust-valve 20 and delivery gauge 21, can regulate test tank exit velocity flow.And chemical feeding points is arranged between flowmeter 6 and the import of test tank 7, the terminal valve group before and after adjusting test tank can realize the method for operation of the two tanks of single tank operation, series operation, pure parallel running and a pump or double pump list tank; Coordinate and regulate the combination valve group in medicine system or enable stand-by pump, all can realize the different adding of agent mode of application; The outlet valve 25 of two test tank 7 bottoms can be communicated with and be merged into an outlet, by main line 1 before reflux pipeline 8 access waterflood pumps, as shown in Figure 1.
Fig. 2 is the structural representation of test tank 7, and the position of adhering to bacterium probe 23 and form 18 in figure is arranged on 15 ~ 30cm place under blind flange, and the blind flange up and down of test tank, form, probe are all detachable; Between upper flange lid and tank body, have liner net, play the effect that is uniformly distributed current, in tank, the end, is also provided with and supports screen 21, plays the effect of supporting filler; And the diameter of filler is between 3mm ~ 20mm, reduce gradually from bottom to top, load height and can make by oneself, it is long-pending that filler can increase substantially tank inner surface, simulation long apart from waterflood-transmission line and improve secondary pollution especially biological membrane pollutant hold back efficiency.
When using this test unit to be used in merely to obtain secondary pollution, research pollutant component, can take following operating scheme: (1) series connection: the water filling a set of unit in pilot system of first flowing through by booster, then outlet valve at the bottom of tank is connected with flexible pipe with import sample valve before another set of tank, make water filling continue, by another set of unit, finally to enter trench.In the 2nd test tank filler size should be than the 1st test tank little or every layer of packed height reduce, can hold back dissimilar secondary pollution.Can opening is front main by the attenuation of pressure reduction and pump discharge flow rate before and after monitoring tank, and the state after taking out filler and lacing film after can opening and before inserting compares and obtain newborn secondary pollution, finally realizes the evaluation to secondary pollution degree.The two tanks of (2) one pumps are in parallel, simulate the split stream of injected water of water-injection plant pump discharge completely to the process of water filling main line: water filling is drawn from main line, only by branching to two test tanks after a side lift pump and flowmeter, in tank, filler stacking state can identically also can be had any different, can also in a certain test tank, use contaminated filler, make test closely may approach the situation in water filling main line; In test, by general import and test tank outlet water quality is compared, monitors the modes such as pressure reduction flow velocity, carry out instant analysis, after can opening by the pollution condition of filler lacing film with insert before contrast.
When being used in prevention of secondary pollution Study on Measures, this test unit especially screens appropriate to the occasion the third method of operation of taking of secondary pollution inhibition medicament, the i.e. method of operation and dosing method completely in parallel: water filling enters respectively two cover test units from main line is drawn, flow through lift pump, flowmeter, test tank, in two test tanks, filler state is identical, by before pump and tank front and back valve group, regulates flow and flow velocity in test tank; Each dosing pump is respectively for a test tank dosing, if the more mode of enabling stand-by pump or taking to change grug feeding jar of medicament kind is achieved.
When this test unit is used for site test, should be set to pure parallel running mode by two cover test units, during site test, can only move 1 cover test unit, test tank bottom blow valve is back to waterflood pump advancing water main line by reflux pipeline, become complete bypass mode, possess directly to the function that adds medicament in injection pipe network.Test tank is as the static mixer of medicament and water filling, and a small amount of glass bead or stainless steel ball filler can be added in its inside, also can be not filled; During dosing, regulate as required medicine system valve group, realize flexible dosing.The water outlet of another set of test unit is not back to water filling main line, can carry out blank test or apply as medicament storage tank thinning tank.
This device is compared tool with existing test unit and is had the following advantages:
Obtaining secondary pollution with regular main line flushing, coil pipe simulation etc. compares with secondary pollution evaluating apparatus, this plant area is little and quick detachable, can simulate long apart from waterflood-transmission line, when water-injection plant is applied, can realize its effectively catching of secondary pollution and quick obtaining, reach the object that monitoring water filling secondary pollution grows situation, evaluates secondary pollution degree; Simultaneously, this device possesses medicament addition device, can be waterflood system secondary pollution and make the test condition that rationally effectively Chemical Inhibition measure facilitates, avoid directly on the underground flooding pipeline of a long distance, directly setting up proving installation and bypass or simulate waterflood-transmission line with large section coil pipe, save cost and the difficulty of construction of test.
