Background technology
To the middle and later periods, it is one of main means of oilfield stimulation that note is poly- for oil field development.At this time a bite injection well need into
Row notes several stratum simultaneously to be gathered to meet geologic requirements, and each note poly layer is generally all different with fluence.It is domestic
Oil field is main in such a way that multitube dispensing and interval dispense for polymer dispensing.Multitube dispensing is greatly and technical due to investing
By casing size limited and can not large-scale promotion, mostly use at present single tube interval dispensing mode.The technique can be realized
2~3 layers of dispensing of single tube, but offshore oilfield layered polymer injection requirement cannot be met.Offshore oilfield injection well is all inclined shaft mostly, and
Completion mode is also variant with the completion mode in land oil field, therefore offshore oilfield cannot generally use the bias in land oil field to match
Note technique, and use concentric allocation process, i.e., distributor and the poly- tubing string of note are concentric structures.However, current layered polymer injection work
Skill especially single tube note polymerizing technology exposes some problems：1, in single pipe layered polymer injection, polymer is injected into stratum by water nozzle,
Current dispensing technology is to form chock pressure difference, control injection rate by reducing area of passage, therefore there are viscosity loss velocities
High (40%~70%) seriously affects the poly- effect driven and recovered the oil；2, lack the research to mating test technology, can not accurately survey
Adjust each layer injection rate of injection well, the requirement of not up to on-demand injection of polymer；Lack corresponding section plane test technique, can not be oil
It hides finely regulating and accurate data is provided；3, when the injection allocation number of plies is more, the number of steel wire operation pulling injection well downhole flow regulator is needed also at double
Ground increases, therefore brings big labor intensity to operating personnel and reduce working efficiency.So existing note polymerizing technology
Less efficient, the adjusting method with fluence is not ideal enough.
