Research of the influence of technogenic factors on the operational reliability of wells
The article discusses the problems relating to optimization of technological modes of oil wells operation. The relevance of the conducted analysis is caused by the necessity of calculation of a well’s potential operational capabilities when choosing pumping equipment for efficient operation and measures to optimize the operation of wells. Technological performance indicators as well as complications associated with a well operation are considered as objects of the analysis. When studying the problem of a well bottom pressure effect on repairs occurrence frequency, their greatest number was noted in the low-pressure area. The results of multivariate disperse analysis prove the fact that the greatest influence on the overhaul period of a well’s operation is exerted by the fluid flow rate as well as a combination of water cut and well bottom pressure indicators, which complements the basic principles and approaches to increasing the efficiency of productive horizons development by controlling depression on the formation during well operation at various modes taking into account the possibility of occurrence of complications and equipment operational failures.
