At the opacity of crude oil, in high pressure vessel, live crude is difficult to measure the height of its rising in the decompressional expansion process, and the utility model embodiment has proposed the device by radargrammetry commercial measurement foam oil lifting height.
Embodiment one
See also Fig. 1, Fig. 1 is a kind of device of measuring foam oil intensity and stability of the utility model embodiment, and this device comprises:
Join sample device 120, be connected, be used to prepare gassiness viscous crude sample to be measured with described oil sample bucket 110;
Sealing-plug 160 is used to seal described oil sample bucket 110.
Heating/heat-preserving container 170 is used to hold described oil sample bucket 110, gives the oil sample bucket 110 heating, and makes it remain on predefined temperature, for measuring gassiness viscous crude sample under the different temperatures.In this heating/heat-preserving container 170 resistive heater is arranged, heat after can switching on.Also can should heat with insulation oil/heat-preserving container 170 is heated to predefined temperature, more described oil sample bucket 110 is positioned in this heating/heat-preserving container 170.
During actual measurement, earlier ready work: under the uniform temperature certain pressure, preparation gassiness viscous crude sample to be measured is stand-by in joining sample device 120.Here said uniform temperature certain pressure sets according to actual oil recovery situation in advance, need consistently with condition in the actual oil reservoir could guarantee the accuracy of measuring; Add insulation oil in the heating/heat-preserving container 170, heating then, insulation oil in heating/heat-preserving container 170 is heated to the temperature that needs, the temperature of just actual oil recovery environment, again oil sample bucket 110 is put into heat-preserving container 170, heating/heat-preserving container 170 also can carry resistance wire, utilizes the resistance wire of heating/heat-preserving container 170 self to heat.The upper end of oil sample bucket 110 is with sealing-plug 160 sealings, and in the present embodiment, said height sensor 140 is radargrammetry instrument, can certainly be that other can measuring height and can reach the measurement equipment of identical effect.The radargrammetry instrument puts in the oil sample bucket 110 by an aperture in the sealing-plug 160, and oil sample bucket 110 has an outlet, and this outlet makes the pressure that top hole pressure is controlled to be needed by pressure control pump 130.At first solution gas is injected in the oil sample bucket 110 by high-pressure pump, in oil sample bucket 110, reach first force value of setting, detect the gas composition that endpiece is discharged, gas composition is identical with the injecting gas component up to discharging, and stops gas injection. and first force value of this setting is identical with force value in the actual oil reservoir; Again join prepare in the sample device 120 the high pressure viscous crude sample that contains solution gas be injected in the oil sample bucket 110 by inlet, the oil sample height reaches 1/10th in the oil sample bucket 110, stops annotating and closing inlet.
When beginning to measure, as shown in Figure 2, in outlet, with certain blowdown rate the pressure in the oil sample bucket 110 is steadily reduced by pressure control pump 130 evenly, reduction along with pressure, gassiness viscous crude sample in the oil sample bucket 110 begins the degassing gradually, under certain blowdown rate, for special viscous crude, the gas of deviating from can not separate rapidly with gassiness viscous crude sample, but be dispersed in the crude oil with the form of disperseing microbubble, form so-called foam oil, cause the huge expansion of former oil volume, the height that expanded foam oil rises in the oil sample bucket 110 is measured and write down to the radargrammetry instrument, the mxm. of this process record is used for characterizing this live crude forms foam oil under this operating conditions intensity.Be reduced to second force value of setting when oil sample bucket 110 internal pressures after, stop step-down, second force value here is that the force value of working during with actual crude oil extraction is identical.Along with the continuous prolongation of time, disperse bubble to merge gradually with crude oil and separate, the height of foam oil constantly descends, and is reduced at last and the suitable height of original gassiness viscous crude height of specimen.Measure and write down the height data in time of foam oil, send these data to data processor 150, handle by 150 pairs of data of data processor, draw out the height varied graph of a relation of foam oil, characterize the stability that this live crude forms foam oil.
Concrete graph of a relation as shown in Figure 3, Fig. 3 is presented under the different blowdown rates, identical gassiness viscous crude sample produces the height of foam oil and the time chart that is reduced to original height.Under blowdown rate 1 situation, the sample foams lifting height is 160mm, and foam is held time (foam is reduced to 0mm from height 160mm time) 170 minutes; Under blowdown rate situation 2 conditions, the sample foams lifting height is 250mm, and foam is held time (foam is reduced to 0mm from height 250mm time) 270 minutes; Show that under blowdown rate 2 situations the ability that sample is produced foam is stronger, foam oil intensity height, and can keep the long period, foam stability is better.Operation in the recovery process had certain directive significance.
Again as shown in Figure 4, Fig. 4 shows that different gassiness viscous crude samples produces foam oil height and time relation figure under identical pressure-lowering condition.Sample 1 foam lifting height is 180mm among the figure, and foam is held time (foam is reduced to 0mm from height 180mm time) 80 minutes; Sample 2 foam lifting heights are 250mm, and foam is held time (foam is reduced to 0mm from height 250mm time) 270 minutes; Shows ability that sample 2 produces foams greater than sample 1, and can keep the long period, and stability better indicates that this crude oil utilizes the foam oil cooling to adopt and has higher recovery percent of reserves that exploitation effect is better.
The device of measurement foam oil intensity that the utility model embodiment provides and stability, can measure the viscous crude that contains solution gas forms foam oil under the different operating condition intensity and stability, for crude oil production provides optimal conditional parameter, to reach exploitation effect preferably
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; and be not used in and limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
