Abstract
The utility model relates to a special oriented flexible screen pipe for drilling and completion, which mainly solves the problems that a traditional flexible drill pipe has a poor orientation performance and is easily damaged. The special oriented flexible screen pipe for drilling and completion is characterized in that: T-shaped openings (2) are uniformly arranged on the wall of a pipe body (1), and T-shaped plugs (3) are arranged in the T-shaped openings (2); the head ends of the T-shaped plugs (3) are welded and fixed on the T-shaped openings (2), and the tail ends of the T-shaped plugs (3) are fixed by strapping plates; and radial slots (4) are radially arranged on the wall of the pipe body (1) at the tail ends of the T-shaped openings (2), and axial slots (5) are axially arranged at the two end heads of the radial slots (4). The special oriented flexible screen pipe for drilling and completion is matched with the flexible drill pipe, has the characteristics of good orientation performance, prevents the flexible drill pipe from being damaged, and is used for supporting the well wall after well completion.
Description
Technical field
The utility model relates to the oil drilling field and cooperates the required flexible screen casing of flex-stem, especially bores the flexible screen casing of the special-purpose guiding of completion.
Background technology
In the oil drilling field, prolong the oil-producing well section in order in oil-gas Layer, laterally to pass through, to reach, improved recovery ratio, avoided the restriction of geographical conditions, saved the resource in soil simultaneously, more and more carrying out horizontal drilling wells.When horizontal drilling, need to adopt flex-stem.And the flex-stem steering capability is poor, and is fragile, directly influences horizontal drilling efficient and cost of production.
Summary of the invention
Poor in order to solve existing flex-stem steering capability, flimsy problem.The utility model provides the special-purpose guiding of a kind of brill completion flexible screen casing.The flexible screen casing of the special-purpose guiding of this brill completion cooperates with flex-stem that to have a steering capability good, prevents the flex-stem damage, is used for the characteristics of the completion support borehole wall.
The technical solution of the utility model is: the flexible screen casing of the special-purpose guiding of this brill completion comprises body.Evenly have T shape mouth on the tube body wall, T shape mouth is built-in with T shape sprue, and T shape sprue head end is weldingly fixed on T shape mouth, and T shape sprue tail end is fixed by tying up plate, on the tube body wall of T shape mouth tail end, radially have radially slot, axially have axial slot to the slot two ends.
The utlity model has following beneficial effect: the special-purpose flexible screen casing of guiding of this brill completion is because employing evenly has T shape mouth on tube body wall, T shape mouth is built-in with T shape sprue, T shape sprue head end is weldingly fixed on T shape mouth, T shape sprue tail end is fixed by tying up plate, on the tube body wall of T shape mouth tail end, radially have radially slot, axially have the structure of axial slot to the slot two ends.Utilize T shape mouth, radially slot and axial slot, the inclination section in the Short Radius Horizontal Wells drilling process creep into the horizontal segment drilling process in, can only can play guide effect from vertically creeping into to be up to the standard to creep into rapidly to a direction bending.Compare the flexible screen casing intensity height of the special-purpose guiding of this brill completion with common screen casing, crooking ability is strong and, under the prerequisite of not losing intensity, improve the pliability of screen casing.And can protect flex-stem, and after completion, should bore the flexible screen casing of the special-purpose guiding of completion and can stay in the well, be used to support the borehole wall.The flexible screen casing of the special-purpose guiding of this brill completion cooperates with flex-stem that to have a steering capability good thus, prevents the flex-stem damage, is used for the characteristics of the completion support borehole wall.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model expanded views.
1-body among the figure, 2-T shape mouth, 3-T shape sprue, 4-is slot radially, the axial slot of 5-.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, the flexible screen casing of the special-purpose guiding of this brill completion comprises body 1.Evenly have a plurality of T shape mouths 2 at straight line on whole body 1 wall, just head end radially open big, it is littler that tail end is radially opened, formation resembles the T font.T shape mouth 2 is built-in with T shape sprue 3, T shape sprue 3 head ends are weldingly fixed on T shape mouth 2, T shape sprue 3 tail ends are fixed by tying up plate, it is fluted to tie up the plate inner face, T shape sprue 3 tail ends place in the groove of tying up plate, tie up plate and be pressed in T shape sprue 3 tail ends outsides, will tie up plate again and be welded on body 1, make T shape sprue 3 tail ends can be up and down.On body 1 wall of T shape mouth 2 tail ends, radially have radially slot 4, axially have axial slot 5, make the flexible screen casing of the special-purpose guiding of this brill completion can be to a direction bending by slot 4 radially to slot 4 two ends.
During actual the use: special-purpose flexible screen casing of guiding of this brill completion and flex-stem are used, should bore the flexible screen pipe sleeve of the special-purpose guiding of completion outside flex-stem, when the inclination section in the Short Radius Horizontal Wells drilling process creeps into and creeps into horizontal segment, under the prerequisite of not losing intensity, improve the pliability of screen casing, can only be to a direction bending, can creep into from vertically creeping into to be up to the standard rapidly, play guide effect.And can protect flex-stem, and after completion, should bore the flexible screen casing of the special-purpose guiding of completion and stay in the well, be used to support the borehole wall.
Claims (1)
1. one kind is bored the flexible screen casing of the special-purpose guiding of completion, comprise body (1), it is characterized in that: evenly have T shape mouth (2) on body (1) wall, T shape mouth (2) is built-in with T shape sprue (3), T shape sprue (3) head end is weldingly fixed on T shape mouth (2), T shape sprue (3) tail end is fixed by tying up plate, radially has radially slot (4) on body (1) wall of T shape mouth (2) tail end, axially has axial slot (5) to slot (4) two ends.
