The invention relates to the technical field of dismounting tools, in particular to a multifunctional pump coiling tool for a vertical fire pump and a using method thereof.The tool comprises a sleeve head, a universal connector and a horizontal rod, the upper end of the sleeve head and the lower end of the universal connector are fixed together, a through hole is formed in the upper end of the universal connector, and the middle of the horizontal rod is arranged in the through hole in a sleeved mode. The device is reasonable and compact in structure and convenient to use, the phenomenon that false information is filled out when the pump is coiled on time due to troubles is eradicated, post staff can coil the pump regularly according to a fire safety management method, and in the subsequent daily inspection process, due to the fact that the pump is coiled on time, the potential safety hazards such as water leakage of a water pump mechanical seal and abnormal pressure are found in time; the water pump is repaired and replaced, it is guaranteed that the water pump works normally in the fire disaster, it is guaranteed that fire-fighting equipment is in a good state all the time, safe production is achieved, and the cost and workload for replacing fan blades are reduced.

The invention relates to a guide and injection integrated structure, an electric field enhanced oil extraction method and a deployment well pattern. The guide and injection integrated structure comprises a shell, an electrode device and a water injection pipe. Holes are formed in the shell wall of the shell to serve as injection points for water to flow into a target oil layer; the electrode device at least comprises an electrode and is arranged in the shell; the water injection pipe penetrates into the shell, and a water injection hole is formed in the pipe wall of the water injection pipe and right faces the injection point. The guide and injection integrated structure can realize simultaneous conduction and water injection of an underground electrode, an electrochemical effect and Joule heat are applied to an underground oil reservoir, and a stratum direct-current electric field is established to influence a rock medium of saturated fluid, so that the electrochemical effect is generated in a stratum; and meanwhile, the direct-current electric field can generate Coulomb force and electric field force which are far greater than differential pressure force in the immediate vicinity of a wellbore, so that the effects of electroosmotic flow, electrowetting, Joule heat, electromigration and the like are generated in a stratum, and the aims of improving the physical property of a reservoir, changing the property of fluid and improving the recovery ratio of the oil reservoir are achieved.
