Analysis And Estimation Of The Molecular Association Polymer

With the development of daqing oilfiled during this thirtyyears.Now oilfied has been to thus situation that the oilfied has 90%water .Some area use high molecular-weight polymer As the oil agentimprove extraction ratio ,but in high temperature and high degree ofmineralization situation, HPAM molecular will be curled.This leads to themolecular weight of polymer descend sharply. Thus the use of polymerwill be restrictly.Many years, the key of selection of polymer in that thepolymer has the capability can resist high temperature and high degreeof mineralization ,the product with the foreground is molecularassociation polymer.The trend of the molecular association polymer hastwo aspect,One is by the way to increase the chain length andrigidity,Which is to say ,increase the hydromechanics dimension ofthe polymer.This can improve viscosity of fluid flow and the capability ofresisting high temperature and high degree of mineralization , butdo not alter degradation with shearing.The other is by the action ofmolecular to increase the hydromechanics dimension of the polymer .Bythis way combine high viscosity and shearing dilution together, toenhence the character of polymer.The molecular association polymerbelong to the second method.In this topic we comparehe the molecular association polymer withhigh molecular weight polyacrylamide in rheological property , and thebasic property,the agreement of alkali and surfactant agent.The studies...
