Research on Hydraulic Self-Enhancement Technology of Fracturing Pump’s Valve Box

Abstract:

It is very important to process acid and fracturing treatment in oil field to improve permeability. The fracturing pump is one of the key equipment for Acid and fracturing treatment. The valve box of fracturing pump is fundamental, costly and wearing parts. Based on the data from domestic and abroad, the life of the valve box is short. Fatigue cracks caused by alternating stress and erosion account for the most invalidation of the valve box. Only increasing structural size and improving material property are not efficient to prolong service life. Related studies show that hydraulic self-enhancement technology is an effective method and it is used widely to improve service life of fracturing pump’s hydraulic parts. Here hydraulic self-enhancement process was simulated by finite element method and 600 Horse Power fracturing pump was studied. The optimal self-enhancement pressure and loading-unloading treatment method are suggested. This study offers a method to found valve box's production technics by hydraulic self-enhancement technology.
