- A perspective way of oil wells operation is to use sucker rod pumps, in combination with oil-gas jet pumps. Placing a jet pump above the dynamic level in the well and operating it simultaneously with the sucker rod pumps allows to stabilize the work of the rod pump, avoid fluctuations of the dynamic level and facilitate the rise of the production liquid to the surface due to the reduction of the density of the mixed flow after the jet pump. In order to implement such oil-gas jet pump in oil wells that are operated by sucker rod pumps, it is necessary to determine their operating modes and choose the most effective among them. A methodology for calculating the operation mode of such well was created that allows determining the efficient location of jet pumps in oil wells and their geometry. When developing this methodology two conditions were taken as a main aim: the whole amount of free gas, which enters the casing annulus of the well, must pass through the oil-gas jet pump and to reach the maximum possible decreasing of the string load. For the 753-D oil well in Dolyna Oil Field calculated efficient operation mode shows the possibility to decrease string load by 26%, reduce electricity consumption and, respectively, investments in oil extraction.
