Abstract
The utility model relates to the technical field of oil field well repairing, in particular to a drillable composite sieve tube. A coupling hoop of the drillable composite sieve tube is connected with an inner body. The inner body is made of drillable metal materials. A non-metal outer body is welded to the outer surface of the inner body and made of drillable non-metal materials. A locking ring is installed and locked on the non-metal outer body. A metal cotton net is welded to the middle of multiple drill holes of the inner body. A sand-proof button is welded to the metal cotton net. By the adoption of the drillable composite sieve tube, a sieve pipe can be drilled and remedial measures such as salvage and lateral drilling are avoided. The efficiency of well repairing work is effectively improved, construction cost is saved, the drillable composite sieve tube is easy to operate, and the performance is safe and reliable. The defects that remedial measures such as salvage and lateral drilling are needed by an existing long-segment casing pipe damaged well, the efficiency of well repairing work is low and the construction cost is high are overcome.
Description
Technical field:
The utility model relates to a kind of oil well technical field, particularly a kind of drillable composite screen pipe.
Background technology:
In the oil-water well of mid-late oilfield development, the casing failure causing due to a variety of causes is the ubiquitous problem in domestic and international each oil field, and damaging is multistage or long section sometimes.For long section casing failure well, often adopt tail tube hanging mode, after tail tube hanging, well diminishes.If occur again damaging, so just need to hang sleeve pipe or the screen casing of less internal diameter.This can cause well more and more less, so that has a strong impact on the enforcement of oil production technology, finally can only beat sidetracked hole, so sidetracked hole is usually used in the casing failure well that cannot repair, and sidetracked hole expense is larger, and the engineering time is long.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of drillable composite screen pipe, and this device has been realized screen casing and can have been bored, and has avoided the enforcement of the remedial measures such as salvaging, sidetracking, effectively improve workover treatment efficiency, save construction cost, simple to operate, performance safety is reliable.Having overcome existing long section casing failure well needs the enforcement of the remedial measures such as salvaging, sidetracking, and workover treatment efficiency is low, the deficiency that construction cost is high.
Technical solution adopted in the utility model is: a kind of drillable composite screen pipe, comprises box cupling and interior body; Box cupling is connected with interior body, interior body adopts the metal material that can bore, nonmetal outer body is welded on the external surface of interior body, nonmetal outer body adopts the nonmetals that can bore, retaining ring installation banding are on nonmetal outer body, metal web is welded in the middle of a plurality of borings of interior body, and it is online that sand control button is welded on metal wool.
The beneficial effects of the utility model are: the utility model is owing to having adopted metal material and the nonmetals that can bore to combine, thereby there is the function that screen casing can bore, avoided the enforcement of the remedial measures such as salvaging, sidetracking, effectively improve workover treatment efficiency, saved construction cost, simple to operate, performance safety is reliable.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of drillable composite screen pipe, comprises box cupling 1 and interior body 2; Box cupling 1 is connected with interior body 2, interior body 2 adopts the metal material that can bore, nonmetal outer body 3 is welded on the external surface of interior body 2, nonmetal outer body 3 adopts the nonmetals that can bore, retaining ring 4 installations banding are on nonmetal outer body 3, metal web 5 is welded in the middle of a plurality of borings of interior body 2, and sand control button 6 is welded on metal web 5.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
