Abstract
The utility model discloses an electric water injection well seal examining instrument which comprises a tube body, an upper pressure gauge, a flow meter, a temperature gauge, a sealing structure, a locating claw and a lower pressure gauge. The upper pressure gauge, the flow meter, the sealing structure, the locating claw and the lower pressure gauge are arranged on the tube body. A controller is additionally arranged on the seal examining instrument, the sealing structure is a seal examining rubber barrel provided with a compression mechanism, and the compression mechanism is connected with the controller. The seal examining instrument is further provided with a motor which is connected with the locating claw through a transmission mechanism. The bearing capacity of the rubber barrel can reach to 25MPa, so that the seal examining instrument can work in the environment with larger pressure. The controller can control the seal examining rubber barrel to compress and stretch through the compression mechanism. Thus, the electric water injection well seal examining instrument is convenient to operate, strong in controllability and capable of accurately judging the sealing effect of a tested layer. The seal examining rubber barrel is additionally provided with a sealing rubber barrel. When the seal examining rubber barrel and the sealing rubber barrel are both sealed, the lower pressure gauge can reflect the pressure of a current stratum. The locating claw is connected with the motor to control the locating claw to be opened and closed at any time. Thus, the seal examining instrument is more flexible in location operation.
Description
Technical field
The utility model belongs to the oil extraction in oil field field, relates to a kind of downhole testing instrument, is specifically related to a kind of electrodynamic type water injection well seal-checking instrument.
Background technology
In order to make up the underground deficit caused after the crude oil extraction, keep or improve formation pressure, realize oil field stable high yield, and obtain higher recovery ratio, must carry out water filling to oil field in the oilfield exploitation later stage.
Existing water injection well seal-checking instrument can accurately show the sealing of seal section to a certain extent, can get rid of packing less illusion that the seal section seepage causes etc.But still there is certain defect in it: on the one hand, what the seal section of tradition seal-checking instrument adopted is the leather cup structure, compress leather cup by own wt during sealing, malfunction, sealing are poor, the bearing capacity of leather cup is poor, and when when 10Mpa is above, leather cup breaks because of high pressure, can't complete and test the envelope purpose, have a strong impact on work quality.On the other hand, the location structure of traditional seal-checking instrument is simple frame for movement, after locating detent work, can only upwards do one-way movement, locates limited, and operating efficiency is low.
Summary of the invention
The purpose of this utility model is in order to improve defect of the prior art, has designed a kind of electrodynamic type water injection well seal-checking instrument, with flexibly, fast seal-checking instrument is positioned at and needs detection position; Improve the sealing of seal-checking instrument seal section, increase work efficiency.
The utility model is to realize that the technical scheme that technical purpose adopts is: a kind of electrodynamic type water injection well seal-checking instrument, comprise body, be arranged on upward pressure meter on body, flow meter, thermometer, hermetically-sealed construction, locating detent, and downforce meter, set up controller on seal-checking instrument, described hermetically-sealed construction for compressing mechanism test the sealing cylinder, compressing mechanism is connected with controller.
Described seal-checking instrument also is provided with motor, and motor is connected with locating detent by transmission mechanism.
Described seal-checking instrument is set up cartridge, and cartridge is connected with compressing mechanism, is positioned at downforce meter lower end.
Beneficial effect of the present invention: the bearing capacity of packing element reaches as high as 25Mpa, makes seal-checking instrument to work under the environment of larger pressure, and controller is controlled compression and the extension of packing element by compressing mechanism, and easy to operate, controllability is strong.Packing element is set to two, is divided into and tests sealing cylinder and cartridge, lays respectively at the two ends of downforce meter, between two packing elements, is independent of each other, and when only testing the sealing of sealing cylinder, can accurately judge the test layer sealing effectiveness; When testing sealing cylinder and cartridge and all seal, the downforce meter can reflect the pressure on current stratum, is convenient to the staff and grasps the strata pressure situation comprehensively.Locating detent is connected with motor, namely locating detent is replaced to original frame for movement with motor drive mechanism, makes the positioning action of seal-checking instrument more flexible, can be tested envelope to any one deck at any time.In addition, the utility model also contains the anti-power failure measure, when compressing mechanism, in compressive state, while circut breaking occurring, can apply certain pulling force to seal-checking instrument, when pulling force is greater than while presetting value of thrust, and the compressing mechanism reduction.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 represents that body, 2 represents that upward pressure meter, 3 represents that locating detent, 4 represents that downforce meter, 5 represents that testing sealing cylinder, 6 represents cartridge.
The specific embodiment
A kind of electrodynamic type water injection well seal-checking instrument, comprise body 1, be arranged on upward pressure meter 2 on body 1, flow meter, thermometer, hermetically-sealed construction, locating detent 3, and downforce meter 4, set up controller on seal-checking instrument, described hermetically-sealed construction for compressing mechanism test sealing cylinder 5, compressing mechanism is connected with controller.
Described seal-checking instrument also is provided with motor, and motor is connected with locating detent 3 by transmission mechanism.
Described seal-checking instrument is set up cartridge 6, and cartridge 6 is connected with compressing mechanism, is positioned at downforce meter 4 lower ends.
During concrete enforcement: Electric Machine Control locating detent 3, at closure state, is placed on position to be measured by seal-checking instrument, the open-shaped state of Electric Machine Control locating detent 3 now, and seal-checking instrument just is fixed on test layer; Then, controller is controlled compressing mechanism, under the drive of compressing mechanism, test 5 compressions of sealing cylinder, test sealing cylinder 5 and oil pipe is separated into to the two parts that do not communicate, utilize the parameter of upward pressure meter 2, flow meter and downforce meter 4 to change, whether the sealing that can judge seal section is good.After testing, controller is controlled compressing mechanism, makes to test sealing cylinder 5 and restores to the original state, and Electric Machine Control locating detent 3 is the state of closing that closes, and seal-checking instrument can move up and down in oil pipe.
Control compressing mechanism when controller, what make to be positioned at downforce meter 4 two ends tests sealing cylinder 5 and cartridge 6 when compressive state simultaneously, can reflect the pressure on current stratum, is convenient to the staff and grasps the strata pressure situation comprehensively.
In addition, the utility model also contains the anti-power failure measure, when compressing mechanism, during in compressive state, circut breaking occurs, can apply certain pulling force to seal-checking instrument, when pulling force is greater than while presetting value of thrust, and the compressing mechanism reduction.
