Abstract:

Current trends in the development of the oil and gas sector of the Russian Federation predetermine the development of new oil and gas fields in the most remote and hard-to-reach regions of the country. These are mainly the northern and northeastern territories, characterized by almost complete absence of transport routes, small population and complex geological features – permafrost soils, and high level of waterlogging of the surface – active – layer. The paper presents the results of a comprehensive study of the influence of these factors on the performance of bored piles for the foundations of field development made of fiberglass pipes. The possibility of monitoring the actual state of pile material by non-destructive method, by installing and studying the degradation of properties of witness samples, is shown. The use of laboratory studies to assess the actual state can hardly be considered optimal, since it requires long-exposures of material samples in specialized containers, which is quite difficult to implement in the conditions of production laboratories.
