The invention belongs to the field of physical experiment equipment of
petroleum and
natural gas exploitation, and particularly relates to a heterogeneous
reservoir water injection commingling interlayer disturbance
simulation system. The
system comprises a constant-flux pump, a plurality of containers, a five-way valve, a core holding unit, an X-
ray tube, a
detector and a
data processing and imaging
system. The constant-flux pump is connected with the inlet of each container through pipelines; the inlet of the five-way valve is respectively connected with the outlet of each container through pipelines. A left sealing cover of the core holding unit is provided with an
injection port, the right sealing cover of the core holding unit is provided with an output port, the inner sides of the left sealing cover and the right sealing cover are sequentially provided with a core end cap
rubber mat, a core end cap and a sealing
rubber mat from outside to inside, a plurality of circular holes are formed in the core end cap
rubber mat, and the core end cap and the sealing rubber mat are provided with a plurality of layer chambers. A plurality of
layers of heterogeneous reservoir slab models are arranged in a sealing rubber sleeve. The outlet of the five-way valve is connected with the
injection port, and fluid passes through the output port and enters a measuring cylinder. The heterogeneous
reservoir water injection commingling layer disturbance
simulation system can reflect layer disturbance degree through the composition and size of liquid amount at the output end, and visualized analysis is achieved.
