Study On The Adaptability Of The Polymer Flooding Mechanical Production System

As the oil well take effect by the polymer in Gu-Dao oil field ,the density of the polymer in the liquid goes up ,the rod side wear serious, because the ability of holding sand become strengthen. As a result ,the pump in low effect and construction multifarious .In order to improve the efficiency of the polymer in oil field , need to carry on the study of the adaptability of mechanical production system after injecting polymer. Through lots of indoor and spot experiment , because of some problem ,such as the low Pump efficiency and the rod side wear serious ,and so on . carry on the study of the adapt ability of mechanical production system , carry on the indoor experiment equipments'designing, the theories model's establishment and the verification test, mainly by the adaptability experiment and research on the pump which get rid of the oil well in the polymer area, analysis the sensitive of mechanical production parameters on the oil well, assurance the oil well production parameter,the match cleft of the oil pump, the density of the polymer, the structure of pump...etc. which influence on the oil well production . the result of the study tell us that as the match cleft increase ,the pump's resistance become lower , base on the variety liquid property, carrying on the adaptability research of the oil pump, researching the low rub resistance pump and the bridge style equipment's which sinking sand pass by the way that absorb from the side , and get the experiment conclusion .Aim at the oil well's tub and rod side wear serious, to improve the rod's Work environment , design the tubing to release the side wear , at the same time , base on the theories study ,indoor experiment, the power test and so on . through the return square , build up the mold of the measure of beam pumping unit well in polymer , overcome the blindness of designing . Improve the parameter of oil well , to raise the work condition . Put forward the comprehensive manage counter plan technique, make use of the low rub resistance pump and the bridge style equipment's which sinking sand pass by the way that absorb from the side,the tool of proving side wear,the tubing and so on . After the construction , gets a obviously economic performance and social performances, increases 29,800 tons l of oil, extension the oil well's producing time more than 110 days at average. This technology have a very important meaning for the Gu-Dao oil-field development.
