Definition of optimum suspension for underground pipes column in flooded sucker rod pump oil wells

A method of definition of optimum underground pipe column suspension in flooded sucker rod pump oil wells is offered. It is noted that the pump submergence depth under dynamic fluid level depends on its suspension and the level of dynamic level. Normal value of submergence comprises 30-40 m. If the actual depth immersion is lower than this value, then the atmosphere air from annular space is soaked into the cylinder, which leads to the corrosion of plunger-cylinder pair units and increases the annular gap and the leakage of fluid through the pen as well. Increasing pump suspension, it is placed to the lower part of operating flooded well, where produced water is accumulated in a great amount. In this case, water rate increases and oil - decreases. In the definition of pump suspension in flooded sucker rod pumping wells, it is necessary to consider above-mentioned facts, moreover, these measures should be carried out after produced water isolation via hydrodynamic method.
