DECISION-MAKING AT REGULATION OF THE TECHNOLOGICAL OPERATING MODE OF PUMPER OIL WELLS ON THE BASIS OF THE THEORY OF ACCIDENTS
The article is devoted to the system analysis of technological indicators of operation pumper oil wells equipped with installations of pumper oil well. Output of oil wells, water and gas, and also delivery rate of the pump are exposed to the analysis. Such analysis is required at decision-making on regulation of work of oil extracting wells. Thus it is necessary to be guided by dynamics of change of the necessary technological indicators during a certain time interval. In most cases for this purpose in practice it is guided, as a rule, by absolute values of indicators that is erroneous as the valuable information, thus containing in initial data on tendencies of behavior of the most operated object is ignored. Thanks to this information it is possible to predict consequences of those or other actions for regulation of operating modes of wells and accordingly to appoint such changes of modes which will promote an oil recovery gain at reduction of drowning rates, economy of reservoir energy at the expense of rational redistribution of the expense of passing gas and hobby of efficiency of pump installations. For the decision of this problem, special criteria of change of operating modes of the extracting wells, based, in particular, on application of elements of the catastrophe theory are used. In article, on the basis of the differential equations known of this theory corresponding to accident of type “fold”, dynamics of change of some technological indicators, such as on outputs of oil, gas and water, and also factor of giving of the pump is modeled. These indicators easily give in to measurement and the account in trade conditions. Their processing makes more weighed decisions based on the simultaneous account of tendencies of change of the most important indicators from a point – sight of regulation of operating modes of chinks. The algorithm of calculation is described and the concrete numerical example is spent. The given settlement scheme is computerized and used for numerous extracting chinks of the enterprises of the production association “Azneft”.
