Abstract
A numerical-control oil extracting device for wells with damaged casings comprises an oil pipe (1), an anti-jacking slip (2), an upper packer (3), a damaged section (4) of a casing, a lower packer (5), a numerical-control electric oil extracting pump (6), a screen pipe plug (7), the casing (8) and an oil extracting target layer (9). The numerical-control oil extracting device is characterized in that the oil pipe (1), the anti-jacking slip (2), the upper packer (3), the lower packer (5), the numerical-control electric oil extracting pump (6) and the screen pipe plug (7) are sequentially connected with one another from top to bottom, and positions with the maximum outer diameters of the anti-jacking slip (2), the upper packer (3) and the lower packer (5) cling to the inner wall of the casing (8). The numerical-control oil extracting device has the advantage that crude oil in the oil extracting target layer (9) on the lower portion of the damaged well section (4) of the casing can be conveniently extracted by the aid of the device.
Description
Technical field
The utility model relates to the petroleum machinery technical field of oil production engineering, especially relates to a kind of casing damage well numerically controlled oil recovering apparatus.
Background technology
At present, known technology is to exploit the purpose oil reservoir of casing damage well pars infrasegmentalis, must first carry out casing salvaging, each casing salvaging not only needs to consume a large amount of man power and materials, and casing salvaging is improper, also can cause oil well to be scrapped, bring huge loss for Petroleum Production unit.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of casing damage well numerically controlled oil recovering apparatus, and this device can not carry out under the prerequisite of casing salvaging, exploits easily the oil in casing damage well pars infrasegmentalis purpose producing horizon.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of casing damage well numerically controlled oil recovering apparatus is provided, this installs this device and is comprised of oil pipe, anti-jack slips, upper packer, casing damage section, lower packet, numerical control electric oil extraction pump, device for plug of sieve tube, sleeve pipe, oil recovery target zone, it is characterized in that: oil pipe, anti-jack slips, upper packer, lower packet, numerical control electric oil extraction pump and device for plug of sieve tube are linked in sequence from top to bottom successively; The maximum outside diameter place of anti-jack slips, upper packer and lower packet is close on the inwall of sleeve pipe, utilizes this device can exploit easily crude oil in casing damage well pars infrasegmentalis oil recovery target zone.Wherein, the effect of upper packer and lower packet is shutoff casing damage well section, stops the liquid in casing damage well section to flow in pit shaft; The effect of anti-jack slips is to sting tight internal surface of sleeve pipe; stop packer to do upper and lower displacement with respect to sleeve pipe; purpose is protecting packer; extend the application life of upper packer and lower packet; the effect of device for plug of sieve tube is that the crude oil that target zone flows out is in time imported the oil pipe inner chamber, and the effect of numerical control electric oil extraction pump is that the crude oil in oil pipe is in time given rise to ground.Utilize this device can exploit easily the interior crude oil of casing damage well pars infrasegmentalis oil recovery target zone.
The beneficial effects of the utility model: by the field trial of the damaged oil well of on-the-spot 5 muzzle pipes, the utility model compared with prior art uses this device can exploit easily the interior crude oil of casing damage well pars infrasegmentalis oil recovery target zone.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is a kind of structural representation of casing damage well numerically controlled oil recovering apparatus.
In Fig. 1: 1. oil pipe; 2. anti-jack slips; 3. upper packer; 4. casing damage section; 5. lower packet; 6. numerical control electric oil extraction pump; 7. device for plug of sieve tube; 8. sleeve pipe; 9. oil recovery target zone.
The specific embodiment
In Fig. 1, casing damage well numerically controlled oil recovering apparatus has oil pipe (1), anti-jack slips (2), upper packer (3), casing damage section (4), lower packet (5), numerical control electric oil extraction pump (6), device for plug of sieve tube (7), sleeve pipe (8), oil recovery target zone (9) to form, it is characterized in that: oil pipe (1), anti-jack slips (2), upper packer (3), lower packet (5), numerical control electric oil extraction pump (6) and device for plug of sieve tube (7) are linked in sequence from top to bottom successively; The maximum outside diameter place of anti-jack slips (2), upper packer (3) and lower packet (5) is close on the inwall of sleeve pipe (8), utilizes this device can exploit easily crude oil in casing damage well section (4) bottom oil recovery target zone (9).Wherein, the effect of upper packer and lower packet is shutoff casing damage well section, stops the liquid in casing damage well section to flow in pit shaft; The effect of anti-jack slips is to sting tight internal surface of sleeve pipe; stop packer to do upper and lower displacement with respect to sleeve pipe; purpose is protecting packer; extend the application life of upper packer and lower packet; the effect of device for plug of sieve tube (7) is that the crude oil that target zone flows out is in time imported the oil pipe inner chamber, and the effect of numerical control electric oil extraction pump is that the crude oil in oil pipe is in time given rise to ground.Utilize this device can exploit easily the interior crude oil of casing damage well section (4) bottom oil recovery target zone (9).
