Abstract

Abstract. Despite the intensive development of low-viscosity oil, which is quite easily extracted from world deposits, the content of high-viscosity oil and bitumen processed in a small direction is continuously developing at a high pace on the world stage. Due to the increased demand for hydrocarbon raw materials, the economy leads to the widespread use of thermal methods of efficient extraction of high-viscosity oil. For a long time it was believed that thermal methods have no prospects due to high energy consumption. In the late 50s-early 60s of the last century, the views of oilmen on the impact of the reservoir by thermal methods began to change for the better. In addition, according to the indicators of cyclic steam and thermal treatment of formations, for every 2-3 tons of water vapor injected into the bottom-hole zone of the formation, it is additionally possible to obtain 1 ton of oil. Due to the lag in the development of the Karazhanbas field by objects of thermal impact, wells after their commissioning work for a long time in the natural mode, i.e. the areas of the deposit were operated in the depletion mode. Such development of the deposit was not provided for by the current technological scheme for the development of the Karazhanbas field by thermal methods and is due to the need to implement the plan for oil production in conditions of chronic lag in the development of fields for active thermal effects on formations. Considering that this lag has already been maintained for quite a long time, it is relevant to conduct an analysis of the operation of wells in the natural mode. The significant field material of the operation of producing wells in the natural mode is summarized.
