Heavy oil diluting device, production pipe column provided with same and heavy oil diluting method
2014
The invention provides a heavy oil diluting device, a production pipe column provided with the same and a heavy oil diluting method. The heavy oil diluting device comprises a column body, wherein at least two axial through holes penetrating through the column body in the axial direction are formed in the column body; side through hole groups are arranged on the side surface of the column body and correspond to the axial through holes respectively, each side through hole group comprises N side through holes, and the N side through holes in the same side through hole group are arranged into at least one row in the axial direction of the column body; the N side through holes in each side through hole group are communicated to the axial through hole corresponding to the side through hole group. According to the heavy oil diluting device, a diluting liquid and heavy oil can be dispersed to enter the diluting device for sufficient mixing, so that the mixing is more uniform, the mixing effect is effectively improved, the pipe column is prevented from blockage, and normal operation of extraction is guaranteed; besides, the use quantity of the diluting liquid can be effectively reduced, and the production cost is reduced.
