Abstract
The invention relates to a sectional type sieve tube completion tubular column. The sectional type sieve tube completion tubular column comprises a sleeve, a drilling string, a pressing seat, a two-layer expansion sealing tool, a sieve tube, an external casing packer and a cementing assembly. The sectional type sieve tube completion tubular column is characterized in that: the sleeve is arranged in a shaft and is connected with the external casing packer; and the drilling string is arranged inside the sleeve, and the bottom of the drilling string is connected with the pressing seat, the two-layer expansion sealing tool, the sieve tube and the cementing assembly in turn. The sectional type sieve tube completion tubular column has the characteristics of long acting solid sealing, and resistance to pressure, temperature and corrosion. The sectional type sieve tube completion tubular column is widely applied to the petroleum drilling process.
Description
One, technical field
The present invention relates to the oil exploitation completion tubular column, particularly a kind of sectional type sieve tube completion tubular column.
Two, background technology
Existing its structure of oil exploitation sectional type sieve tube completion tubular column is that the fill-type external casing packer is installed on the sleeve pipe; come expansion filling formula external casing packer by clear water or completion fluid; purpose is that the segmentation completion is carried out at the oil reservoir position; with the protection oil reservoir; improve recovery ratio; isolate different pressures layer or profit alternating layers, realize reasonable High-efficient Production.But it exists following shortcoming or deficiency simultaneously: 1. because the compressive strength of packing element own is not enough; 2. easily aging under downhole temperature pressure and well liquid erosion state, easily inefficacy; 3. the life-span weak point can not adapt to permanently effective stratified operation, separate zone production; 4. cement can not be injected and be used in the external casing packer of segmentation sieve tube completion.
Three, summary of the invention
The purpose of this invention is to provide a kind of sectional type sieve tube completion tubular column, adopt double-deck envelope instrument and the screen casing co-ordinative construction of expanding, both carried out the segmentation completion practice effectively, overcome the shortcoming or the deficiency that exist in the above-mentioned prior art again effectively.
Sectional type sieve tube completion tubular column of the present invention, comprise sleeve pipe, drill string, impacting seat, double-deck envelope instrument, screen casing, external casing packer, the cementing assembly of expanding, it is characterized in that described sleeve pipe installs in pit shaft, be connected with external casing packer on it, described drill string is installed in sleeve pipe, it is connected with impacting seat down in turn, double-deck envelope instrument, screen casing and the cementing assembly of expanding.
Wherein, described impacting seat comprises outer adapter sleeve and the lower contact A that is connected in turn of top connection A and its, with central tube A that is connected in turn in it and plug seat, is installed on piston and snap in the upper annulus between described central tube A and the adapter sleeve.Described piston middle part is fixed by shear pin A and central tube A.The described bilayer envelope instrument that expands comprises in the box cupling A central tube B of connection, box cupling E and lower contact B in turn, is connected and installed with screen casing A, box cupling B, leather cup A, box cupling C, box cupling D, leather cup A, screen casing A in turn between the outer and box cupling E of box cupling A.Central tube B between described box cupling A and the box cupling E is provided with annular space outward.Described cementing assembly comprise top connection B and on leather cup B, ball-and-seat, screen casing B and the guide shoe of connection in turn.Described ball-and-seat valve seat is fixed by shear pin B and valve body.
The present invention has following advantage compared with prior art:
1, adopts long-acting entity sealing, improve sealing effectiveness and packing ability;
2, the ability that has withstand voltage, heatproof and resistance to chemical attack is difficult for losing efficacy;
3, packing ability height, long service life.
