The wax deposition of the oil well can cause the blockage of the oil well, influence the yield and seriously cause the accidents of production stop or damage of oil extraction equipment and the like. In the field of oil recovery in oil fields, downhole tools affect oil recovery efficiency due to wax deposition. Wax deposition prevention by a wax deposition prevention device is required. The existing wax deposition prevention device has the problems of prolonging the wax deposition well section, increasing the wax deposition amount and shortening the well washing period due to the structural reason, so that the high-efficiency operation period of equipment is shortened, and the well repairing cost is finally increased.
In the existing wax deposition prevention method: patent CN 101538458A, published as 2009, 9.23 discloses an oil well dispersion paraffin inhibitor and a preparation method thereof, which is a new developed chemical paraffin inhibitor. But the chemical wax-proofing agent has relatively high cost and has certain influence on the dehydration of the later-stage united station. In addition, some anti-scaling and anti-wax deposition devices adopt a physical method, and because the anti-scaling and anti-wax deposition device has a single anti-wax deposition structure, poor anti-scaling and anti-wax deposition effects and is inconvenient to use, the production period of an oil field is shortened, the well washing frequency is increased, the production efficiency is reduced, the production cost is increased, and the popularization and the application are not facilitated.
