...Introduction The dimensionless characteristic curve of sucker rod pump Pump characteristic curve Downhole system of sucker rod pump can be seen as a special kind of plunger pump with its outstanding characteristic of a few hundred to several thousand meters of elastic rod string between...

... of the produced fluid, force the oil companies to continuously optimize their facilities to meet the actual requirements regarding efficiency. One step in the chain of oil production from the reservoir to the customer is the optimization of artificial lift systems in mature oil fields. Nowadays sucker rod pumping...

..., pump depth increases continuously because energy and dynamic liquid level of developed reservoirs decline. As the main lifting way, sucker rod pump wells accounts for 65% of the total number of wells in Tarim oilfield. Pump depth of the deepest rod pumped well reaches 5200 meters in Tarim. During...

... was shut down as per the operator's instructions. The pump was pulled out and was inspected for any possible degradation following the production decline. The well was then allowed to undergo second steam cycle beyond which the well was continuously producing with Sucker rod pump again...

... and studied under the condition of single pump system. In Xinjiang oil field, combined lift method of sucker rod pump and injection pump has been successfully applied in wells where thin oil is doped into heavy oil to decrease the viscosity. It is shown that combined-type consecutive lifting method...

... as 20xx[AD1]) completed for a natural lift with no provision for installing artificial lift system. Later, it was recommended to install Sucker Rod Pump (SRP) as the most suitable Artificial Lift (AL) system. Conventionally sucker rod down-hole pump is installed by running a barrel assembly on the bottom...

... Abstract After 1859, sucker rod pump was invented commercially by C. E. Drake 1 , it was used vast majority of wells throughout the world. Thus, it became an oil symbol which comes to mind first for people even who are not engaged in this industry. Although SRPs are installed in about 90...
