## ABOUT THE TECHNIQUE OF GROUPING OF OIL WELLS WITH SHOWS OF GAS BY THEIR POTENTIAL POSSIBILITIES ON THE BASIS OF PARETO PRINCIPLE

It is known, that actions carried out on oil fields for regulation of modes of extracting wells have adaptive character, and mention not what individual objects, and all difficult interconnected and co-operating system of the elements making the developed deposit, set of operational and delivery chinks, and also a complex ground-based equipment. Such big and difficult system it is expedient to operate with use of the system approach. Thus splitting on a number of technological indicators of all fund of wells on separate groups, from for decrease in volume of the processed information, essentially simplifies and reduces the price of all managerial process. Besides at the system approach to become effective as more detailed analysis of expediency of carrying out of actions in each group, and their planning within the limits of all system as a whole. In article as such method based on the system approach, grouping of wells by their potential possibilities proceeding from characteristics of hyperbolic distribution of oil outputs are offered. In practice, as a rule, similar properties the big and difficult systems where and it is possible to carry all process borehole workings out of deposits possess. It is known, that the behavior of these systems submits to Pareto principle, and distribution дебитов chinks on their size also corresponds to this principle. Unlike known works where, basically, are described to the mechanism of grouping of the chinks, based on quantitative signs, to article the algorithm of their “qualitative” grouping that allows to reduce and unify quantity of distinguished groups is resulted and to give them obviously known properties, inherent every possible to the versions met in practice. The number of distinguished groups is defined by quantity of processed indicators. As initial data it is used monthly average selections of oil, gas and water on each chink. The algorithm of redistribution set chinks on eight groups, based on known property of hyperbolic distribution is stated. The given settlement scheme it is computerized and approved on a real example of the extracting wells equipped with pumper oil wells with installations and takes root for the various enterprises of a production association “Azneft”. Regularly carried out calculations allows to watch dynamics of change of a condition of the chinks passing from one group in another that can promote construction of adaptive model of process of operation for all fund of wells.
