Sucker rod pump is the most widely used mechanical oil production technology in the world. At present, 90% of the total number of oil wells in the world are produced by machinery, of which 85% are pumped by rod pump, and about 75% are pumped by rod. Therefore, the current rod pump manufacturers have a great space for development.
One of the key components of mechanical pump production system is the sucker rod.
Due to the lack of flexibility, corrosion resistance, weight and strength of steel sucker rod, it can not meet the needs of ultra deep well production. After 107 fatigue tests, the residual strength is 90%, while the residual strength of steel sucker rod is only 30% ~ 40%. Therefore, the use of carbon fiber continuous sucker rod greatly extends the service life of the sucker rod. Moreover, the carbon fiber continuous sucker rod has good flexibility, the minimum radius of curvature is 300 mm, and the continuous length of the rod can reach more than 1000 meters. The whole sucker rod has only two joints, the upper and the lower, which reduces the probability of breaking off, and is conducive to mechanized operation, which is a major innovation of the rod pump manufacturer.
In addition to joints and safety devices, there are also new types of work vehicles, mine computer software, and related technologies supporting industrial production site operations. Moreover, the carbon fiber coiled tubing truck takes into account the functions of raising and lowering the coiled tubing at the same time, realizing the integrated operation in the oil production field.
Sucker rod pump manufacturers continue to actively explore innovation, the arrival of new technology will produce good economic benefits, especially the effect of energy saving will be particularly significant.
