Adopt the utility model discloses can prevent that oil field oil recovery in-process paraffin crystallization from appearing, block up oil recovery pipe, reduce crude oil viscosity, improve the extraction volume of viscous crude well to can protect groundwater resources effectively, prevent the industrial pollution of groundwater resource.
Description
Technical field
The utility model relates to a kind of wax removal viscosity reduction device, in particular to a kind of producing well environment-friendly type vortex flow wax removal viscosity reduction device.
Background technology
At present, in the oil recovery process of oil field,, on wall casing, make the flow string area of passage reduce output decline, energy consumption increase, also may cause oil well to block along with decrease of temperature paraffin can be separated out.Therefore, wax control and wax removal are important steps in recovering the oil.The existing conventional method of removing long-pending wax in oil field is to adopt the mechanical type paraffin scraper, when long-pending wax is serious, then need feed hot water, and vapours is heated or injected the chemical agent wax removal.The subject matter that these methods exist is time-consuming taking a lot of work, and injects the chemical agent wax removal, and what have in the material that chemical agent and paraffin reaction back produce is poisonous, groundwater resources have been polluted, in the process of decomposing paraffin, cause the minimizing of paraffin output, and paraffin is useful subterranean resource.
The utility model content
Technical problem to be solved in the utility model is to propose to prevent in the oil recovery process of a kind of oil field that wax crystal from separating out, stopping up flow string, reduces viscosity of crude, simultaneously the environment-friendly type vortex flow wax removal viscosity reduction device of polluted underground water resource not.
Technical scheme provided by the utility model is: a kind of environment-friendly type vortex flow wax removal viscosity reduction device, comprise shell body, electromagnetic generator and vortex flow generator, shell body is provided with line outlet, the two ends of shell body are provided with the external screw thread that matches with tubing coupling, electromagnetic generator is connected on the inwall of shell body, is connected with non-magnetic bolt between vortex flow generator and the electromagnetic generator.
Further, electromagnetic generator comprises electromagnet and electric power coil, and the electric power coil is located at the periphery of electromagnet, and the vortex flow generator is the cup-shaped metallic object.
Further, electromagnetic generator and vortex flow generator are distributed in the shell body for two or more sets.
The utility model has following advantage: prevent that flow string is separated out, stopped up to wax crystal in the oil recovery process of oil field, reduce viscosity of crude, improve the produced quantity of heavy oil wells, and can protect groundwater resources effectively, prevent the industrial pollution of groundwater resources.
