Abstract
The utility model discloses an anti-pollution eccentric water distributor, which is composed of a distributor body and a blanking plug in the distributor body. The utility model is characterized in that the distributor body is provided with a communication chamber communicated with the water outlet of the blanking plug, the lower of the communication chamber is provided with a deposition cavity, the upper of the communication chamber is provided with a water outlet chamber with an internal spring, the spring abut against a valve ball seals the water outlet above the communication chamber, the wall of the distributor body at the upper of the communication chamber is provided with a water outlet communicated with the water outlet chamber. When the water pressure of the water filled from the blanking plug is higher than the oil layer pressure and the abut force of the spring, the filled water lifts off the valve ball and enters into the oil layer from the communication chamber and the water outlet of the distributor body, and when no water filling, the valve ball abut against the oil layer pressure and the spring seals the communication chamber to prevent the reflux of the filled water and prevent the pollution on the pipe string from the foreign materials of formation.
Description
Technical field
The utility model relates to a kind of oil field well instrument, particularly a kind of anti-pollution eccentric injection mandrel.
Background technology
Injection well downhole flow regulator is the seperated layer water injection down-hole instrument that use in the oil field, and existing injection well downhole flow regulator generally is made up of injection well downhole flow regulator main body and the blanking plug of installing in it, offering delivery port on the injection well downhole flow regulator main body is communicated with the weep hole of blanking plug, the water under high pressure that injects enters oil reservoir through blanking plug from the delivery port on the main body, but existing blanking plug is provided with way flow mechanism simple realization and prevents that formation water from refluxing, but its blanking plug inner space is little, the injecting process hydraulic loss reaches the poor reliability of valve greatly, survey to need in the debug process blanking plug taken out and change water nozzle, formation water can flow into tubing string and pollutes in this process.
Summary of the invention
The purpose of this utility model is not have way flow mechanism in order to solve existing injection well downhole flow regulator, when water injection well stops annotating, formation water refluxes, the impurity that is deposited in the near wellbore zone enters water injection string and causes the tubing string pollution problems, and a kind of anti-pollution eccentric injection mandrel above-mentioned shortcoming, that have way flow mechanism that overcomes is provided.
The utility model is made up of injection well downhole flow regulator main body and the blanking plug that is installed in the injection well downhole flow regulator main body, it is characterized in that, in the injection well downhole flow regulator main body, be provided with connected chamber, this connected chamber is connected with the delivery port of blanking plug, the top of connected chamber is provided with water chamber, be provided with spring in this water chamber, this spring contact one valve ball shutoff weep hole place above connected chamber, the injection well downhole flow regulator main wall that is positioned at connected chamber top offers delivery port and is connected with water chamber.The bottom of connected chamber can be provided with deposit cavity, has reduced impurity to the ball-and-seat Effect on Performance.
Operating principle of the present utility model is:
The utility model constitutes a way flow mechanism by connected chamber, water chamber, spring and valve ball, when the hydraulic pressure that injects water from blanking plug during greater than the ejection force of the pressure of oil reservoir and spring, the water that injects backs down valve ball, and the water of injection enters oil reservoir by connected chamber from the delivery port of injection well downhole flow regulator main body; When stopping to inject water, valve ball blocks connected chamber under the ejection of the pressure of oil reservoir and spring, and the water of previous injection can not be refluxed, thereby can not cause the pollution of tubing string because of stratum impurity; The setting of deposit cavity can make the impurity deposit cavity wherein, reduces the pollution of impurity to tubing string, and has reduced impurity to the ball-and-seat Effect on Performance.
The beneficial effects of the utility model:
Because of the utlity model has way flow mechanism, when stopping to inject water, valve ball blocks connected chamber under the ejection of the pressure of oil reservoir and spring, and the water of previous injection can not be refluxed, thereby can not cause the pollution of tubing string because of stratum impurity; The setting of deposit cavity can make the impurity deposit cavity wherein, has reduced the pollution of impurity to tubing string, and has reduced impurity to the ball-and-seat Effect on Performance.

Fig. 1 is the cross-sectional schematic of the utility model embodiment.
Fig. 2 is the whole cross-sectional schematic of the utility model embodiment.
Fig. 3 is the A-A cross-sectional schematic among Fig. 2.
The specific embodiment
See also Fig. 1, Fig. 2, shown in Figure 3, the utility model embodiment is made up of injection well downhole flow regulator main body 1 and the blanking plug 2 that is installed in the injection well downhole flow regulator main body, it is characterized in that, in injection well downhole flow regulator main body 1, be provided with connected chamber 3, this connected chamber 3 is connected with the delivery port 21 of blanking plug 2, the bottom of connected chamber 3 is provided with deposit cavity 4, the top of connected chamber 3 is provided with water chamber 5, be provided with spring 6 in this water chamber, this spring 6 contacts one valve ball, 7 shutoff weep hole place above connected chamber 3, injection well downhole flow regulator main body 1 wall that is positioned at connected chamber 3 tops offers delivery port 8 and is connected with water chamber 5.
Operating principle of the present utility model is: when the hydraulic pressure that injects water from blanking plug 2 during greater than the pressure of oil reservoir,
The water that injects backs down valve ball 7, and the water of injection enters oil reservoir by connected chamber 3 from the delivery port 8 of injection well downhole flow regulator main body 1; When stopping to inject water, or the pressure of oil reservoir is when injecting the pressure of water, and valve ball 7 blocks connected chamber 3, and the water of previous injection can not be refluxed, thereby can not cause the pollution of tubing string because of stratum impurity.
The utility model has solved existing injection well downhole flow regulator and has not had way flow mechanism, and conductor string is subjected to the problem from the stratum contaminating impurity easily.
