Abstract
Currently, many large fields with a massive gas cap have an acute problem of breakthrough gas from gas caps produced during the development of oil from thin oil rims. One of the possible ways to limit gas production and reduce the gas factor is periodic operation of wells. To accelerate the alignment of the gas cone and return the fund to production during periodic operation, re-injection of degassed oil into a reservoir is used. The paper analyzed the field experience of periodic operation of wells with the injection of degassed oil. In order to perform high-quality comparative calculations of different options, hydrodynamic modeling of periodic operation of wells and re-injection of oil into the reservoir was used based on the digital model of the Srednebotuobinskoye field (SBOGCF). Based on the modeling results, the main patterns were identified. When modeling periodic well operation, the number of shutdowns and shutdown duration were used as variable indicators; when modeling periodic operation with degassed oil injection, the volume of injected degassed oil was added to the variable indicators during modeling. The cumulative oil production was used as a control indicator. The modeling results show that periodic well operation and degassed oil injection lead to an increase in cumulative oil production for all calculation options. At the same time, if we compare the options with periodic operation with the option of periodic operation with oil reinjection into the reservoir, then oil reinjection into the reservoir in volumes of up to 100 m3 does not lead to additional oil production compared to pure periodicity.
