Abstract
The invention provides an expansion screen pipe which comprises an inner layer pipe, a middle layer pipe and an outer layer pipe, wherein the inner layer pipe, the middle layer pipe and the outer layer pipe are fixed and mounted in a sleeved mode in sequence from inside to outside. Multiple kerfs are distributed in the pipe wall of the inner layer pipe, the middle layer pipe is formed by coiling filaments spirally, and multiple holes are also distributed in the pipe wall of the outer layer pipe. The expansion screen pipe has the advantages that the granulometric class of filtered gravel can be controlled accurately, an oil drainage area is enlarged through expansion hole enlargement, oil flow resistance is reduced at the same time, and crude oil produced by a single well daily can be improved by 30-50 percent.
Description
Technical field
The invention belongs to field of petroleum exploitation, especially relates to a kind of expandable screen.
Background technology
At present in field of petroleum exploitation, employing be all traditional screen casing, the drainage area of traditional screen casing is little, oil flow resistance is large, screen construction rigidity is on the low side, the damage that is easy to subside, cementing quality cannot ensure in addition.It is excessive that its surface and internal surface of sleeve pipe are left over space, just need to take gravel pack, and gravel pack is an operation that expensive quality is changeable.Expandable screen technology (Expandable Sand Screen,) be a kind of emerging sand control technique, the sand control screen hole enlargement of expanding in underground construction, this technique is applied first in Oman Thayfut5 well, after operation, desanding effect is obtained certainly, although this technology propagates into all over the world, comprises the North Sea, Southeast Asia and China's Bohai Bay Oil application.But the uncontrollable filtration of its expansion process gap, general gap will expand several times, does not reach possibly anticipation desanding object.
Summary of the invention
The invention provides one can control gap, the expandable screen that desanding effect is desirable.
The technical scheme that the invention adopts is: a kind of expandable screen, comprise inner layer pipe, intervalve and the outer tube of fixing successively from inside to outside suit, on the tube wall of described inner layer pipe, be distributed with some slots, middle tube is formed by filiform coiled coil, is also distributed with some holes on the tube wall of described outer tube.
Preferably, the slot length in described inner layer pipe is 20～100mm, and wide is 1～10mm, on tube wall, is uniformly distributed.
Preferably, described middle tube is coiled to form continuously by stainless steel wire spiral.
Preferably, the hole on the tube wall of described outer tube is circular hole, and diameter is 5～20mm; Or be slotted hole, its length is 5～30mm, wide is 1～10mm; Or be slotted eye, on tube wall, be uniformly distributed.
Preferably, the length of stating inner layer pipe two ends is greater than the length of described intervalve and outer tube, and one end is provided with external screw thread, and one end is provided with internal thread.
Preferably, the two ends rounding off of described slot.
Advantage and good effect that the invention has are:
1, the accurate sandstone grade of controlled filter;
2, expansion hole enlargement drainage area increases, and reduces oil flow resistance simultaneously, and individual well daily output crude oil improves 30-50%;
3, owing to expanding, tube wall is directly exerted pressure, ensure cementing quality completely, to the withstand voltage 50MPa of bobbin seal; In the time that Open-Hole Section uses, bottom is sat and is hung configurable earth anchorage.The liquid bonding guarantee circumferential seal reliability of upper expansion suspension arrangements;
4, this programme expandable screen external surface approaches internal surface of sleeve pipe, can exempt gravel pack, greatly reduces engineering cost;
5, screen casing porous section and the equilibrium of linkage section expansion resistance; The circumferential pantostrat of screen casing forms arch (bridge) type statically determinate structrue, and general structure rigidity is large, stablize the durable deformed damaged that is difficult for;
6,, after expanded downhole, the gap between the stainless steel wire of composition middle tube is controlled.
Brief description of the drawings
In order to be illustrated more clearly in the invention embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only the embodiment of the invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the invention embodiment, the technical scheme in the invention embodiment is clearly and completely described, obviously, described embodiment is only the invention part embodiment, instead of whole embodiment.Based on the embodiment in the invention, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the invention protection.
A lot of details are set forth in the following description so that fully understand the invention, but the invention can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the condition without prejudice to the invention intension, and therefore the invention is not subject to the restriction of following public specific embodiment.
Secondly; the invention is described in detail in conjunction with schematic diagram; in the time that the invention embodiment is described in detail in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be done local amplification; and described schematic diagram is example, it should not limit the scope of the invention protection at this.In addition in actual fabrication, should comprise, the three-dimensional space of length, width and height.
As shown in Figure 1, the invention comprises from inside to outside inner layer pipe 1, intervalve 2 and the outer tube 3 of fixing suit successively, on the tube wall of described inner layer pipe 1, be distributed with some slots, middle tube 2 is formed by filiform coiled coil, is also distributed with some holes on the tube wall of described outer tube 3.
Slot length in described inner layer pipe 1 is 60mm, and wide is 5mm, is uniformly distributed the two ends rounding off of described slot on tube wall.
Described middle tube 2 is coiled to form continuously by stainless steel wire spiral.
Hole on the tube wall of described outer tube 3 is circular hole, and diameter is 10mm; Or be slotted hole, it is long is 20mm, wide is 5mm; Or be slotted eye, on tube wall, be uniformly distributed.
The length at described inner layer pipe 1 two ends is greater than the length of described intervalve 2 and outer tube 3, and one end is provided with external screw thread, and one end is provided with internal thread, is convenient to 1 of many inner layer pipe and interconnects.
When use, construction technology is simple and convenient, the invention is put into the sleeve pipe pre-setting, sleeve pipe is placed in drilling well, the below of the invention is disposed with expand swollen head and anchoring device, in the time of sleeve closure perforated interval, after going into the well, utilize the drilling rod hydraulic pressure of feeding, make the bay pressure-raising of anchoring device top, bottom, promote to move on the swollen head of middle part expansion, the swollen head that expands is got in inner layer pipe 1, supportted large, make its expansion hole enlargement, the recycling mechanical force direct pull-up swollen head that expands, upper screen continues to expand, until after screen casing bulk expansion, the swollen head that will expand proposes, expand and finish.
