Description

Technical Field

[0001] The utility model relates to the technical field of oil field exploitation, in particular to an automatic water mixing device. Background Art

[0002] Oil and water wells are holes drilled according to the well layout system planned for oil field development to extract oil. They are channels for oil to rise from the bottom of the well to the wellhead. Oil wells are holes drilled by drilling methods. Generally, after the oil well reaches the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas and water layers. Then, according to the requirements of oil field development, the oil layer is opened with a perforating gun to form a channel, and the oil pipe is lowered. The oil is raised from the bottom of the well to the wellhead using appropriate inducing flow methods.

[0003] During oilfield exploitation, a water mixing device is needed to mix water inside the oil and water well. The Chinese utility model patent with announcement number CN210460614U discloses an automatic water mixing and dosing device for oil and water wells, including a base, a blower and a material box. The air outlet end of the blower is connected to the left end of the first feeding pipe through a check part, the right end of the first feeding pipe is connected to the left end of the second feeding pipe through a flange, and the right end of the second feeding pipe is fixed with an annular discharge part.

The utility model utilizes the first and second feeding pipes to form an injection pipe. When water addition or drug addition is required, the blower is started and the opening valve is opened, which greatly simplifies the operation process and can realize automatic water addition or drug addition to oil and water wells at a lower cost.

[0004] However, during use of this utility model, since there is no corresponding stirring device between the medicine storage chamber and the water storage chamber, when the medicine solution and clean water are output at the same time, the two cannot be fully mixed, which may lead to poor water addition effect inside the oil and water wells and cannot meet production needs. Therefore, an automatic water addition device is proposed to solve the above problems. Utility Model Content
