IMPROVING THE RELIABILITY OF THE HYDRAULIC PART OF THE OILFIELD PUMP, TAKING INTO ACCOUNT THE SELECTION OF MATERIAL FOR THE SEAL ASSEMBLY
Abstract
Many years of experience in the operation of oilfield equipment during underground well repair shows that ensuring the reliability and durability of the pumping units used is one of the main elements of the process chain, largely determined by the quality and performance characteristics of the friction units of the hydraulic parts of the pumps.
It is known that high-pressure oilfield pumps used in the repair of oil and gas wells carry out various technological works, including cementing, hydraulic fracturing, acid treatment, washing sand plugs and other washing and squeezing operations.
Parts of the hydraulic parts of the pumps are subjected to abrasive, corrosion-mechanical and corrosion-abrasive wear, which often leads to sudden failures, fraught with emergencies, additional costs and loss of time for unscheduled repairs.
The article considers the possibility of increasing the reliability of plunger oilfield pumps due to the correct removal of the material of the sealing collars and improving the assembly scheme. It is also proposed to use the diffusion monotonic distribution as a model of failure to evaluate the reliability function of the selected best compression scheme. Since this distribution model is a more flexible function that better aligns qualified data, compared to the well-known two-parameter strict probability models.
The results of the work have theoretical and practical prerequisites for assessing the reliability of field pumping units and may be useful for specialists working in this field
