Description
Technical field
It the utility model is related to SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL and adjust stream control water completion technique field, more particularly to a kind of gravel particle
Insulate pit shaft henchnmrk test device.
Background technology
It is to adjust stream water-control sieve tube typically to use packer pair as core that SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL, which adjusts stream control water completion technique,
Net horizontal section carries out insulating the annular space between horizontal segment tune stream water-control sieve tube and the borehole wall.If packer is long, whole tubing string
Risk be present in tripping in；If packer is too short, there is risk in the sealing of packer.At present, with the continuous improvement of scientific and technological level,
The packing to annular space between screen casing and reservoir can be realized instead of packer using the gravel particle layer of filling.
SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL adjusts the integral construction tubular column structure of stream control water completion technique as shown in fig. 1, in the tubing string
In, laid in horizontal segment and adjust stream water-control sieve tube 11, pressed in the upper end of screen casing equipped with filling converter 12, filling packer 13.
