pre-injection

The state of mercury film on the surface of wall-jet glassy carbon electrode under different pre-plating mercury conditions in flow injection analysis-differential pulse anodic stripping voltammetry has been studied with microscope and microphotograph, and thereby suitable condition for pre-plating mercury was obtained.

通过显微观察，研究了在流动注射一示差脉冲阳极溶出伏安法中，使用壁喷玻碳电极时，在不同的预镀汞膜条件下，在电极表面上形成的汞膜的状态。

In profile control formula system, because of existing bibulous situation of high permeability reservoirs in injection wells, injecting method is used of cross-link polymer gel take along pre-pay angiocardiography expansion particles which can block off high permeability advantage channel.

在调剖配方体系上，根据水井有高渗透层的吸水情况，采用交联聚合物凝胶携带预交联体膨颗粒注入，封堵高渗透优势通道。

Studied the water shutoff method, witch pre-treatment formation with high concentration of polymer, optimize water shutoff parameters by means of perpendicularity test, including mass fraction of polymer, intake volume of polymer, injection rate of polymer and permeability.

研究了用高浓聚合物预处理地层的堵水方法，正交试验法优化了堵水参数，包括高浓聚合物质量分数、高浓聚合物注入量、注入速度和地层渗透率极差。
