The authors of the article consider the problems of horizontal wells operational efficiency estimation for various systems of oil fields development on the example of a formation site with average reservoir characteristics similar to Vikulov sediments of Krasnoleninsk dome as well as compare operational modes of horizontal and directional wells. The estimation is based on the prediction calculation results of oil reserves recovery made by using the beforehand prepared geological-technological model of the developed site of the formation. The results of the mathematical mode of three-phase filtration allowed comparing the horizontal and directional wells operational efficiency for the different wells location systems and wells spacing. The results of calculations proved the fact that horizontal wells efficiency is higher than that of directional wells that was manifested by producing wells high flow-rates and increased final recovery increase in case of one-line well location system.
