Description
Technical field:
The utility model relates to the used water-quantity regulating device of water filling, especially water injection well integrated form device for adjusting and measuring in the oil recovery field, oil field.
Background technology:
In the construction manufacturing process was recovered the oil in the oil field, water filling was as one of important method of oil reservoir voltage stabilizing, volume increase, and the oil field is widely used at home.Keep formation pressure by water filling, realize oil field stable high yield and improve the effective ways of oil field development effect, in order to keep formation pressure, must control water injection rate, generally should adopt now and place blanking plug in the eccentric injection mandrel seating nipple, water injection hole is arranged on the blanking plug, realize controlling water injection rate by the size of regulating the blanking plug water hole, and existing blanking plug because of reasons in structure exists easy sand card, governor motion can't be realized the problem of constant current control, increased to survey and transferred workload and survey the accent difficulty, influenced to survey and transferred efficient, be unfavorable for applying.
The utility model content:
Can't realize the problem of constant current control in order to solve existing easy sand card of blanking plug and governor motion, the utility model provides a kind of water injection well integrated form device for adjusting and measuring, this water injection well integrated form device for adjusting and measuring not only can the sand control card, and can realize governor motion constant current control.
The technical solution of the utility model is: this water injection well integrated form device for adjusting and measuring comprises power transmission shaft, spool and lower house, and spool links to each other with lower house by screw thread, and transmission shafts is covered with spool in driving groove; Be equipped with the valve seat in spring base, upper spring and drag-out hole under the lower house internal thread successively, be covered with in the valve seat and have and the corresponding piston of fluid hole, be connected with the water nozzle Inductance valve in the piston lower end, be covered with lower spring on the outer step of water nozzle Inductance valve, the outer step bottom of water nozzle Inductance valve is equipped with the oil field water nozzle.Upper spring and valve base chamber in the such scheme are equipped with packing ring, and upper spring touches on packing ring mutually.
The utlity model has following beneficial effect: this water injection well integrated form device for adjusting and measuring is owing to take such scheme, on power transmission shaft, be processed with the driving groove that Open Side Down, be covered with spool in the driving groove, flow down in silt particle deadweight effect and water like this, silt particle can not form deposition, play the effect of anti-silt particle, effectively protected transmission mechanism normally to move; When needs are regulated the water nozzle size, drive transmission component by the measurement and adjustment instrument device, spool is axially moved along the lower house internal thread, area of passage between regulating spool and the piston is regulated injection rate.When water injection pressure changes, rely on outer spring balancing inlet of water nozzle Inductance valve and liquid outlet front and back pressure reduction, reach the purpose of constant flow rate, guaranteed the water filling quality.
Description of drawings:
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model;
Accompanying drawing 2 is Fig. 1 middle and lower part structural representations.
1-power transmission shaft among the figure, 2-spool, 3-lower house, 4-spring base, 5-upper spring, 6-packing ring, 7-valve seat, 8-fluid hole, 9-piston, 10-water nozzle Inductance valve, 11-step, 12-lower spring, 13-screw thread, 14-driving groove, 15-oil field water nozzle.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with shown in Figure 2, this water injection well integrated form device for adjusting and measuring comprises power transmission shaft 1, spool 2 and lower house 3 by Fig. 1, is with spool 2 in the power transmission shaft 1 axial driving groove 14, and its driving groove lower end is an opening; Spool screw thread 13 links to each other with lower house 3, be equipped with the valve seat 7 of spring base 4, upper spring 5 and drag-out hole (8) under lower house 3 internal threads successively, be covered with in the valve seat 7 and have and fluid hole 8 corresponding pistons 9, piston is connected with water nozzle Inductance valve 10 in 9 lower ends, be covered with spring 12 on the water nozzle Inductance valve 10 outer steps 11, water nozzle Inductance valve 10 outer steps 11 bottoms are equipped with oil field water nozzle 15.After this water injection well integrated form device for adjusting and measuring drops in the inclined to one side hole of conventional eccentric injection mandrel, rely on cam locked in hole partially, inject water and inject the stratum by the flow channels between filter bowl, oil field water nozzle 15, water nozzle Inductance valve 10 and the spool.When needs are regulated water nozzle Inductance valve 10 sizes, drive power transmission shaft 1 by measurement and adjustment instrument, spool 2 is axially moved along lower house 3 internal threads, area of passage between regulating spool 2 and the water nozzle Inductance valve 10 is regulated injection rate, plays the purpose of adjusting.When water injection pressure changes, rely on spring 12 balance inlets and liquid outlet front and back pressure reduction outside the water nozzle Inductance valve 10, reach the purpose of constant flow rate, guaranteed the water filling quality.So this water injection well integrated form device for adjusting and measuring not only can the sand control card, and can realize the constant current control of device for adjusting and measuring.
