Abstract

Abstract: It is difficult to obtain the satisfactory inhibiting result by one kind of inhibitor for oilfield application,so several kinds of inhibitors are always combined to reach expected inhibiting effect by their synergistic interactions.In this paper,the simplex optimization method is used to seek the optimal formulation of polyacrylic acid (PAA),polyaspartic acid (PSAP),ethylenediamine tetramethylene phophonic acid (EDTMP) and critic acid (CA) according to the salinities of injected water and formation water in a certain oilfield in China.The average inhibition ratio is used as response variable in optimization.The optimal formulation is finally obtained through twelve trials and the optimal formulation of inhibitors is PAA∶PASP∶EDTMP∶CA = 58.6∶14.8∶4.9∶21.7（V/V）.This result shows that the method used in this paper is simple,accurate and quick to design and optimize formulation of inhibitors.

Key words: simplex optimization, optimization, scale inhibitor, formulation
