Preferably, the box cupling inner surface is connect with the base tube outer surface thread.
On the other hand, the present invention provides a kind of segmentation sand control completion tubing string, in two-part segmentation sand control pipe from upper and
Under be followed successively by hanging packer, Intelligent sieve tube, section packer, Intelligent sieve tube, silk plug.
Preferably, it is set as female thread at the top of the Intelligent sieve tube, for connecting the hanging packer that bottom is pin thread；It is described
Intelligent sieve tube bottom is set as pin thread, for connecting the section packer that top is female thread；The section packer bottom end setting
For pin thread, for connecting the silk plug that top is female thread.
Compared with prior art, the invention has the following advantages:
The present invention according to technological measure require be connected to working string, two-part segmentation sand control pipe in from top to bottom according to
Secondary is hanging packer, Intelligent sieve tube, section packer, Intelligent sieve tube, silk plug；According to different production oil production methods, intelligence is sieved
Pipe can be selected be equipped with soluble metal material or when temperature is higher than 200 DEG C fusible property high molecular material Intelligent block body；Pipe
Under column in place after, hanging packer and section packer are suppressed by pump truck while being set in ground, after the completion of setting, suspension packing
Device rotating forward is given up, and part of giving up finally is played out.
For often adopting well, since Intelligent sieve tube is immersed in production layer liquid, Intelligent block body is soluble metal material, with
The extension of time, constantly dissolve, ultimately form production channel, dissolution time can be according to requiring to be set as 1~30 day.For
Thermal production well, the Intelligent block body of Intelligent sieve tube is the fusible property high molecular material when temperature is higher than 200 DEG C, due to steam injection temperature
For degree more than 200 DEG C, Intelligent block body, which melts to establish steam injection and handle up, in steam injection process produces channel.
In the present invention, it may be implemented to suppress in oil pipe during tubing string is gone into the well etc. by Intelligent sieve tube, oil jacket annulus be isolated
Function, thus simplify technological measure tubing string, reduce working procedure, shorten construction period, save operating cost.
Detailed description of the invention
Fig. 1 is the partial profile structure of Intelligent sieve tube of the invention；
Fig. 2 is the structural schematic diagram of segmentation sand control completion tubing string of the invention.
Specific embodiment
