Abstract
For prevention and combating paraffin deposites different chemical regents are widely used (wax inhibitors). In field conditions many ways of chemical regents dosing are applied. Injection of chemical reagents in oil well tubing is the most effective for wax inhibitors; in this case consumption of reagents is largely decreasing by comparison with chemical reagents dosing through the well-casing annulus. The article describes design and operating processes of technology of wax inhibitor dosing in electric centrifugal well pumps installation. This process opens fluid access to oil well tubing at higher pressure at the wellhead. Reagent RT-1-3 is used as aromatic wax inhibitor. In RT-1-3 there is butylbenzene fraction of Kazanorgsintez PJSC containing a mixture of butylbenzene, isopropylbenzene and polyalkylbenzene.
