Economic Effects Evaluation of a High Temperature Polymerflooding Pilot in Shuanghe Oilfield

By using the numerical simulation results of hightemperature polymerflooding and optimized waterfloodingin Zone Ⅱ5 in Shuanghe oilfield as the basis ofcomparation, we studied the evaluation procedures andindexes of polymerflooding with the comparative analysismethod of technical innovation project evaluation,analyzd cash flow and calculated profit and loss balancelimits .Evaluation results show that the economic benefit ofthis polit test is high and the evaluation procedure andindexes are practical.
