Blowout Prevention Deep Well Rod Pump Development

With the increase of deep well,the change of formation pressure often causes oil pressure,casing pressure increases sharply,if oil drilling in the area,the tubing string running and the pump,the oil will overflow mouth along the well,cause of environmental pollution on the ground,cause certain influence to the well drilling,oil extraction work.To pump suitable for deep pump requirements,and has good reliability,high pump efficiency,reduce the liquid is sufficient or even smoke with spray oil overflow well problems in oil Wells,we on the structure of conventional rod pump is developed,and designed a blowout deep well pump rod type,effectively solve the deep well pump efficiency is low,the pump failure rate high and prevent the next tubing and pump oil spill accidents in the process,improve the service life of oil well pump,improve recovery factor.Through this topic research and development of rod pump spray a deep well meet the requirements of the following technologies:(1)The tubing and the pump process,ensure the string seal,not overflow;(2)Compared to the conventional deep well pump to adapt to the working position depth: pump deepening pump hang 500 ~ 1500 meters;(3)Pump efficiency is not lower than 35%;(4)Meet the maximum stroke 6 ~ 8 meters;(5)Blowout deep lever type pump structure design,form series products.
