Abstract
The utility model relates to a downhole device for chemical injection exploitation to a pumping well in particular to a well with thick oil and high waxy oil. The utility model is composed of an upper reducer union 1, a sealing ring 2, an upper centralizer 3, a connecting screw upper centralizer 4, a mixing mandrel 5, an upper mixing impeller 6, an impeller adapter sleeve 7, a mixing impeller assembly 8, a lower mixing impeller 9, a connecting screw of the lower centralizer 10, a lower centralizer 11 and a reducing coupling 12. The utility model has the advantages of reasonable design, novel structure and high reliability. The liquid in the chemical agent injection oil well can be mixed fully by the device of uniformly mixing liquid for chemical agent injection oil well to reduce the resistance of the liquid flow and to improve the technical effect of chemical agent injection. The device of uniformly mixing liquid for chemical agent injection oil well also has the function of strengthening the pumping rod and preventing the eccentric wearing.
Description
Technical field:
The utility model relates to a kind of particularly downhole hardware of viscous crude, the exploitation of high waxy oil well chemical injection of pumpingh well that is used for.
Background technology:
Chemical injection be heavy oil wells viscosity reduction, the clear wax control of high waxy oil well and de-plugging of well so that its ordinary production a kind of important process measure.At present, the scene is in carrying out the chemical agent injection process, and the stirring of liquid stream makes it mixed uniformly downhole hardware in injection chemical agent and the well owing to be not used in, thereby not only causes the injecting consumption big, cost of production increases, and the effect of whole chemical injection technological measure is caused adverse effect.
Summary of the invention:
The utility model purpose is to provide a kind of and can fully stirs liquid in the chemical injection oil well well, and can reduce liquid flowing resistance, the chemical injection oil well liquid that improves the chemical injection technological effect all loads in mixture and puts.
The utility model is to realize like this.This kind liquid all loads in mixture to put by last reducer union, sealing ring, upper and lower centralizer, upper and lower centralizer connecting screw rod, stirring mandrel, upper and lower agitator arm, impeller adapter sleeve, paddle wheels, following sub-coupling to be formed, be socketed with centralizer on the last centralizer connecting screw rod, its upper end is connected with last reducer union internal thread with screw thread, and last reducer union is provided with sealing ring; Stir the mandrel upper and lower end and be connected with upper and lower centralizer connecting screw rod with screw thread respectively, be set with agitator arm, paddle wheels and following agitator arm on the mandrel from top to bottom successively, be separated by with the impeller adapter sleeve between each impeller; Be set with down centralizer on the following centralizer connecting screw rod, following centralizer lower end is connected with following sub-coupling.During use, the last reducer union of this device is connected with the sucker rod of its upper and lower respectively with following sub-coupling.When injecting chemical agent, upper and lower reciprocating motion along with rod string, upper and lower agitator arm on this device and paddle wheels therebetween can liquid stream stirs in liquid and the well to injecting, make it abundant mixing, thereby play the effect that reduces liquid flowing resistance, gives full play to injection chemical agent usefulness.
The utility model is reasonable in design, novel structure, reliable operation, utilize it to stir to liquid in the injection chemical agent oil well well, play the effect that reduces liquid flowing resistance, improves the chemical injection technological effect, this device also has the function of setting upright sucker rod and anti-eccentric wear, is suitable for and applies.
