Embodiment 1
[0009] A water injection device according to the present invention comprises a water injection pipe 1, and the lower part of the water injection pipe 1 is provided with a pump cylinder 2, a motor, a water pump 3 and a water suction pipe in sequence, and the water suction pipe extends to the outside of the pump cylinder 2 and connects with the water injection pipe 1 Connected, the pump cylinder 2 is provided with a water outlet.
[0010] The water injection device of the present invention uses a packer to fix the water pump 3 in the water layer at the bottom of the oil production well, starts the water pump 3 to work, and guides the water pumped out by the water pump 3 to the water injection pipe 1 through the water suction pipe. The water pipe 1 is injected into the pump cylinder 2, and flows from the pump cylinder 2 into the oil layer to be injected.

The invention provides a water filling device and relates to a water filling device, in particular to a water filling device for an oil well. The water filling device comprises a water filling pipe and is characterized in that a pump cylinder, a motor, a water pump and a water pumping pipe are arranged at the lower part of the water filling pipe in sequence; the water pumping pipe extends to the outside of the pump cylinder and is connected with the water filling pipe; and a water outlet is formed on the pump cylinder. The water filling device has the benefits that water in a water layer is pumped out and filled into the water filling pipe through the water pump and enters the water filling layer from the water filling pipe; and the water filling device is simple in structure and high in practicality.
Description
technical field [0001] The invention relates to a water injection device, in particular to an oil well water injection device. Background technique [0002] With the deepening of oil field development, more and more wells need to be injected with water, and the cost of water injection will also increase accordingly. If it is in a remote and water-scarce area, if the current water injection process is adopted, pumping stations and pipeline networks will also need to be built , to invest high costs, how to reduce the cost of water injection and oil recovery has become the direction of water injection technology research. Contents of the invention [0003] The invention relates to a device for pumping out water in a water layer and injecting it into an oil production well. [0004] A water injection device according to the present invention includes a water injection pipe. The lower part of the water injection pipe is sequentially provided with a pump cylinder, a motor, a wa...
