The article deals with problems of efficiency of well stock usage in long-term developed and exploited oil fields. Such oil fields are usually characterized by production drop and layer pressure, intensive flooding, necessity of frequent overhauls and various geological-technical measures. However, in spite of a great amount of drilled wells, the efficiency of them is extremely low. On the basis of actual production data of Apsheronneft Oil and Gas Development Board of Azneft Production Union, the improvement possibilities of usage of wells in whole have been studied. Via application of statistical methods more informative signs characterizing technological regime of stock of the wells with high rate of flow are defined. It was shown that by adjustment of specific parameters of wells with high rate of flow, it is possible to achieve stabilization and increase the rate of flow of separate wells and the total production of whole considered stock.
