Abstract
A method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.
Claims6
A method of lubricating an oil production pump, the method comprising the steps of:
- providing a polarized lubricant including an emulsifier and a polar compound, and water for diluting the polarized lubricant to produce a diluted lubricant, wherein a volume ratio of water to polarized lubricant being in the range of 3:1 to 7:1;
- circulating a mixture of the diluted lubricant into a flow path of the oil production pump so that the diluted lubricant reacts with components of the oil production pump and forms a protective barrier on the components of the oil production pump;
- operating the oil production pump to pump out oil from a ground.
