OPTIMIZING DESIGN OF OIL PUMPING SYSTEM TO IMPROVE ITS EFFICIENCY

Beginning from the power consume of oil pumping system, the import energy could divide into electrical energy and gas expend energy while the consume energy could divide into availability energy and consume energy of well pumping unit, of viscidity sluggish and of glide friction. Basic on this, a realism calculation method of oil pumping system efficiency was fished out. Using the calculation formula of energy, the system efficiency which each parameter takes part in was calculated. With the object of higher system efficiency and better income and the principle of selecting merit from the whole, a series oil pumping parameters were selected, which could implement the aim to optimize design of parameter selection. This technology can improve system efficiency great scope.
