使用单一药剂往往难以达到满意的阻垢效果,通常采用几种单药剂进行复配,复配剂在油田阻垢性能上有明显的协同增效作用.运用改进单纯形优化法,以我国某海上油田注入水和地层水矿化度为例,选用聚丙烯酸(PAA)、聚天冬胺酸(PASP)、乙二胺四亚甲基磷酸(EDTMP)和柠檬酸(CA)为单纯形因素,以平均阻垢率为单纯形响应值,进行药剂复配优化设计.经12次实验,找到了最优配方,PAA∶PASP∶EDTMP∶CA=59.4 15.7∶4.6∶20.3.实验过程表明,该方法在寻优过程中具有简单、准确以及实验次数少的优点.

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.
