Abstract
An oil well bridging plug testing apparatus is composed of an oil pipe (1), a hydraulic anchor (2), a packer (3), a bridging plug testing flow controller (4), a check valve (5) and a plugging bridging plug (6), and is characterized in that the oil pipe (1), the hydraulic anchor (2), the packer (3), the bridging plug testing flow controller (4) and the check valve (5) are connected in sequence; and tightness of the bridging plug in an oil well can be conveniently tested by using the apparatus.
Description
Affiliated technical field
A kind of oil well that the utility model relates on the oilfield is tested bridging device, this device has oil pipe [1], hydraulic anchor [2], packer [3], tests bridging plug restriction choke [4], ball-and-seat [5] and blocked bridge plug [6] form, and uses this device can check easily the sealing of bridging plug in the oil well.
Background technology
At present, known technology is not have oil well to test bridging device after oil well is beaten bridging plug, and its major defect is that the reliability of bridging plug in the oil well can not effectively be checked, and causes heavy losses often for Petroleum Production unit.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of oil well to test bridging device, uses this device can check easily the sealing of bridging plug in the oil well.
The technical scheme that its technical problem that solves the utility model adopts is: adopt a kind of oil well to test bridging device, this device has oil pipe [1], hydraulic anchor [2], packer [3], test bridging plug restriction choke [4], ball-and-seat [5] and blocked bridge plug [6] form, it is characterized in that: oil pipe [1], hydraulic anchor [2], packer [3], test bridging plug restriction choke [4], ball-and-seat [5] is linked in sequence, the effect of oil pipe [1] is to carry the liquid that pumps in the well, the effect of hydraulic anchor [2] is fixedly oil pipe and packer, stop packer [3] and ball-and-seat [5] that length travel occurs, the effect of packer [3] is the annular space that envelope is cut oil pipe and sleeve pipe, the effect of ball-and-seat [5] is only to allow the liquid in the sleeve pipe to enter tubing string, do not allow the liquid in the oil pipe to enter sleeve pipe, the effect of blocked bridge plug [6] is that the shutoff plan will by the oil reservoir of bridge plugging [8], use this device can check easily the sealing of blocked bridge plug [6] in the oil well.
The beneficial effects of the utility model: by field trial, the utility model compared with prior art uses this device can check easily the sealing of bridging plug in the oil well.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
(accompanying drawing) is the schematic diagram that a kind of oil well is tested the structure embodiment of bridging device.
Among the figure: 1. oil pipe; 2. hydraulic anchor; 3. packer 4. is tested the bridging plug restriction choke; 5. ball-and-seat; 6. blocked bridge plug; 7. artificial bottom of a well; 8. plan will be by the oil reservoir of bridge plugging; 9. the oil reservoir that will exploit of plan; 10. oil well casing
The specific embodiment
In the accompanying drawings, adopt a kind of oil well to test bridging device, this device has oil pipe [1], hydraulic anchor [2], packer [3], test bridging plug restriction choke [4], ball-and-seat [5] and blocked bridge plug [6] form, it is characterized in that: oil pipe [1], hydraulic anchor [2], packer [3], test bridging plug restriction choke [4], ball-and-seat [5] is linked in sequence, the effect of oil pipe [1] is to carry the liquid that pumps in the well, the effect of hydraulic anchor [2] is fixedly oil pipe and packer, stop packer [3] and ball-and-seat [5] that length travel occurs, the effect of packer [3] is the annular space that envelope is cut oil pipe and sleeve pipe, the effect of ball-and-seat [5] is only to allow the liquid in the sleeve pipe to enter tubing string, do not allow the liquid in the oil pipe to enter sleeve pipe, the effect of blocked bridge plug [6] is that the shutoff plan will by the oil reservoir of bridge plugging [8], use this device can check easily the sealing of blocked bridge plug [6] in the oil well.
