The Numerical Simulation Of Injection And Erosion Of Horizontal Well Fractured Sand Blower

The corrosion is the important breakage factor of life and modern industry. In theflowing system, there is a relative motion between the surfaces of quality and metal tomake metal surface corrosion worse. The impact speed of amboceptor and the impuritiescontained of the inner part to all accelerate the degree of the quality to the wearing away ofmetal wall. When the fluid sneaks into solid again, it namely constitute a liquid-soliddouble phase flow corrosion. It is the important reason that arouses various parts, such aspump, valve and piping in the professions like the petroleum, chemical engineering andwater conservancy water electricity to in great quantities damage. Therefore the research ofthe corrosion problem is urgent.The topic of the text is horizontal well pressing crack sand blower flow patternanalysis and research of instructional improvement. When horizontal well pressing crack.Under construction, it is with increase of construction quantity and add the amount of sandand the corrosion of sand blower also turns worse. The estimate about corrosioncircumstance of sand blower can provide basis for the operation row of the pressing crackconstruction and add amount of sand。It is not only to take a lot of time but also to lackeconomy to predicting wearing rate just though the ground erosion wear experiment. Butthe sand blower theorial model is built up and imitate flow appearance of sand blower.analyzed flow, speed and contain amount of sand upon the structure surface. Built up blunteclipse model, and applies the blunt eclipse model to CFD to get of flow a field，with thehelp of Fluent of disspered phase, to calculate biggest to hurtle eclipse of sand blowerbetween in the speed in the10m|s and20m|s and contain amount of sand quantity in6%and12%.According to the biggest blunt eclipse rate to calculate the biggest blunt of theeclipse of pipeline And predict to in response to the maintenance time of circumstance. Apipeline is supposed as10-meter-long.Its inner radius is10centimeters and its outer radiusis15centimeters to predict maintenance time.This text is carefully analyzed the basic parameters which influence hurtles eclipseand comes true the imitation of flow condition and the predict of erosion and corrosion.Itis usefull to spot operate to have certain instructional meaning.
