Until when the pasta in main cavern 7 is maintained at certain liquid level, the pressure of injection water is adjusted, so that the stream of injection water
Amount control is in specified numberical range, then measures by the discharge outlet 17 of each point of cavern the displacement of each point of cavern；It connects
It and constant-flux pump 3 is recycled to be transported in water injection pipe 9 by delivery pipe 10, then water curtain is injected by water injection pipe 9 water of discharge
Tunnel 6 is realized the cycle injection of water, is so injected repeatedly, and measure the displacement of each point of cavern every time, divides hole by observation
The variation of indoor drainage amount judges the uniform performance of water curtain system moisturizing and the uniform stability of moisturizing, when dividing hole in detection
Displacement occurs simultaneously in indoor displacement to be increased and during the situation of displacement reduction, illustrate to occur inside point cavern to block with
Channelling phenomenon, displacement increase then show channelling occur during moisturizing, and displacement reduces not even draining and then illustrates moisturizing
Occur congestion situations in the process, when there are above-mentioned two situations, show that the stability of water seal cave depot water charging system has occurred
Variation；
The present invention is by controlling the oil mass of oil-in 11 and oil export 12, so as to effectively control the height of oil product in main cavern 7
Degree, then to same water quality water being used to carry out moisturizing under different oil product height, by specifically testing measurement, obtain oil product liquid level height
Spend influence to water charging system stability, then by the way that oil product is controlled moisturizing to be carried out using different water quality water, led in specified altitude assignment
It crosses specific experiment measurement and obtains influence of the different quality parameter to water charging system stability, overall construction design is ingenious rationally,
Convenient for practical experiment.The device of the invention can simulate the three-dimensional large-sized simulation dress of water curtain system in large-scale crude oil water seal pit hole library
It puts, by produced-water reinjection Seepage Experiment, tests out influence after produced-water reinjection to cave depot rock permeability and to cave depot
The influence of moisturizing systems stabilisation obtains water quality index parameter to the space transfusion performance of water charging system and moisturizing systems stabilisation
Affecting laws, determine each index of water quality.
It these are only specific embodiments of the present invention, but the technical characteristic of the present invention is not limited thereto.It is any with this hair
Based on bright, to realize essentially identical technique effect, made ground simple change, equivalent replacement or modification etc., all cover
Among protection scope of the present invention.
