Abstract
The utility model discloses an ultralow shear polymer demand regulator for alkaline-surfactant-polymer (ASP) flooding, and belongs to the oil field polymer demand regulator. The demand regulator comprises a valve body, a valve rod and a valve core, wherein a valve cover is arranged at the upper end of the valve body, an outlet is formed in the lower end of the valve body, an inlet is formed in the side wall of the valve body, the valve rod passes through the axis of the valve cover to be in threaded connection with the valve cover, the lower end of the valve rod is connected with the valve core placed inside the valve body, the valve core is a valve core body which comprises two butt-jointed cones and is thick in the middle and thin at the two ends, and the valve body is in clearance fit with the valve core. The ultralow shear polymer demand regulator for the alkaline-surfactant-polymer flooding disclosed by the utility model is reasonable in design, simple in structure, convenient in operation, low in manufacturing cost, conductive to production. The inside of the demand regulator disclosed by the utility model adopts a special mechanical structure so that the liquid flowing through the inside of the regulator can achieve low shear to keep the polymer at the outlet part at pretty high viscosity; and the valve rod is in threaded connection with the valve cover and the longitudinal position of the valve rod is regulated to achieve the control of the clearance between the valve core and the valve body so that the accurate flow control can be achieved.
Description
Technical field
The utility model belongs to the oilfield polymer flow regulator, particularly relates to a kind of ultralow shearing polymer flow rate adjuster that ternary is driven that is used for.
Background technology
The polymer flooding tertiary oil recovery is applied by large-scale industrialization as one of important technique measure of east China old filed stable yields.Because polymer flooding has the characteristics of high investment, high economic risk, in order to reduce the whole economic efficiency of input, reduction risk, raising polymer flooding, will optimize and annotate the polymerizing technology flow process, and annotate the polymerizing technology flow process and realize optimizing, the distribution of polymer solution flow is regulated and is absolutely necessary.Existing polymer flow rate adjuster is because of reasons in structure, to the viscosity reduction effect of polymer various degrees, and complex structure, operation inconvenience causes cost to raise, and influences ordinary production.
Summary of the invention
The utility model provides a kind of ultralow shearing polymer flow rate adjuster that ternary is driven that is used for, to remedy the deficiencies in the prior art.
A kind of ultralow shearing polymer flow rate adjuster that ternary is driven that is used for of the present utility model, be to constitute by valve body, valve rod and spool, be provided with in the upper end of valve body that valve gap, lower end are provided with outlet, sidewall is provided with import, the axle center that valve rod passes valve gap is threaded with it, and the lower end of valve rod connects the spool that places in the valve body.
As further improvement of the utility model, the thin valve core in thick two in the middle of described spool is formed by two bullet butt joints, and valve body and spool matched in clearance.
As further improvement of the utility model, the valve rod of valve gap top is provided with handwheel.
As further improvement of the utility model, the lower end of spool is a hemispherical.
A kind of ultralow shearing polymer flow rate adjuster that ternary is driven that is used for of the present utility model, reasonable in design, simple in structure, easy to operate, cost of manufacture is low, be beneficial to production; The special cone of mechanical structure of its inner employing of the utility model, feasible its inner liquid of flowing through can be realized ultralow shearing, thereby keeps the polymer in exit to have higher viscosity; Valve rod is threaded with valve gap, adjusts the upper-lower position of valve rod, realizes can controlling flow accurately to the clearance control between spool and the valve body; The utility model is that the viscosity retention ratio to polymer solution reaches 100% under the 2.5MPa in differential pressure; Differential pressure be under the 3.0MPa to the viscosity retention ratio of polymer still greater than 96%.
