Description
Technical field
The utility model relates to oil field development field, specifically a kind of observation simulated a variety of well pattern steam and drive situation
Experimental box.
Background technique
It yet there are no the physical simulating device for simulating various well patterns of handling up.However, carrying out oil reservoir development design, well pattern
It is critically important content with well spacing, various well pattern types cut both ways, and need to carry out physical analogy to its effect, to observe reality
The throughput prediction of object simulation.
" inverted nine-spot pattern " each unit be a square, centre have a bite producing well and eight mouthfuls of periphery water injection well or
Steam injection well.By the note of 9 method areal well patterns, adopt well exchange position after become anti-9 method well patterns.Its note adopts well number ratio
For 1:3.Due to 9 method well pattern notes, well number is adopted than high, therefore frequently with inverted nine spot water flooding pattern or steam injection.
The steam injection well of " five-spot pattern " is arranged in the center of square, and 4 mouthfuls of producing wells of surrounding are located at 4 tops of square
Point.The ratio between steam injection Jing Jing number and producing well well number are 1:1, thus the water injection rate task that every mouthful of steam injection well undertakes is medium.
The steam injection well of " seven spot pattern " is arranged in the center of regular hexagon, and 6 mouthfuls of producing wells of surrounding are located at 6 of regular hexagon
Vertex.In seven spot pattern, every mouthful of steam injection well influences 6 mouthfuls of producing wells of surrounding, and every mouthful of producing well is by 3 mouthfuls of steam injection well shadows around
It rings.In this well pattern, the ratio between steam injection Jing Jing number and producing well well number are 1:2, i.e. every mouthful of steam injection well averagely undertakes two mouthfuls of oil recoveries
The water injection rate task of well, such water injection rate task is than the task weight that the steam injection well of four-spot pattern and five-spot pattern undertakes.
" nine-spot pattern " steam injection well is arranged in the center of square, 8 mouthfuls of producing wells of surrounding be located at 4 vertex of square with
On the central point of four edges, every mouthful of steam injection well influences 8 mouthfuls of producing wells of surrounding.This 8 mouthfuls of producing wells are divided into end hole and corner well: 4 mouthfuls
Producing well positioned at square four edges midpoint claims end hole, and in addition 4 mouthfuls of producing wells for being located at square four vertex are known as corner well,
The injector producer distance of corner well is 1.4 times of the injector producer distance of end hole.Every mouthful of end hole is influenced by 2 mouthfuls of steam injection wells around, and every bicker
Well is then influenced by 4 mouthfuls of steam injection wells around.In this well pattern, the ratio between steam injection Jing Jing number and producing well well number be 1:3, i.e., every mouthful
Steam injection well averagely undertakes the water injection rate task of 3 mouthfuls of producing wells.Such water injection rate task is heavier.Nine-spot pattern steam injection well number compared with
Less, the heavier water filling task that every mouthful of steam injection well undertakes is main disadvantage.
Current steam flooding three-dimensional physical simulation device is all to carry out physical analogy to injection, the simple scenario to recover the oil, no
It is simulation " well pattern ", there is presently no the steam of " simulating all kinds of well patterns " to drive physical simulation experiment device.
