Research On Wells Deep Pumping Technology

This paper divides deep pumping wells into two parts that is based on the depth of the pump in the wells, including optimizing pumping rods, pumps and matching tools and improving working system by actually implement effects, to form pumps with their matching wells deep pumping technology.At present, deep pumping wells have no detailed definition of the pump setting depth. We define vertical wells which can produce oil as deep pumping wells from the fact of Liao Xing Oil & Gas Development Company’s production and the definition of depth of medium-deep well. We separate the deep pumping wells into two kinds:one is the well whose pump setting depth is between 2000 meters and 2400meters, adopting common D level rods to satisfy the intensity demand of rods and seldom fatigue break, the other one is the well whose pump setting depth is below 2400 meters which adopt common D level rods that easily fatigue wear.On this basis, we optimize averting eccentric wear tools, types of pumping rods,special deep pumps and other matching down hole tools by combing with actual production of our company. For the wells whose pump setting depth is below 2400 meters, we adopt the technology which contains special pumping rods instead of common D level rods, pump efficiency tools with matching averting wear tools to improve intensity of pump rods, wells pump efficiency, guaranty wells deliverability, prolong cycle of pump inspection. Finally, we develop well deep pumping technology which adapt to Liao Xing Oil & Gas development company according to two kinds averting eccentric wear technique.
