Abstract (English):
One of the key problems of modern oil production is high water cut in produced fluids. In Russia, this problem is especially relevant, since a significant portion of oil is produced at old, depleted fields, with water cut often exceeding 90% [1-2]. Currently, there are various methods for combating water cut, primarily, repair and insulation work (RIW). Effective implementation of workover and isolation (RIW) operations, can slow down the trend of increasing associated production of excess water from producing wells. However, modern technologies have a number of significant drawbacks: high reagent losses, deterioration of reservoir properties, the need for repeated work, significant downtime of wells due to the duration of work, etc. [1, 3]. The authors of the article propose a new high-tech solution for RIW - smart microcontainers (SMC). SMC is a hollow capsule filled with an active substance, which opens and begins to react under the influence of certain physical factors. The article announces the SMC-RIW technology, which consists of the following stages: injection of the composition with SMC, retention and release in the target interval (loss-circulation / water-bearing zone). Thus, the use of the technology significantly increases the efficiency of insulation work due to the selective action in the near-wellbore zone of the formation and controlled setting / curing of the composition. At the moment, work is underway to implement the SMC technology in the processes of the oil industry, including, in addition to RIW, drilling, chemical methods of enhanced oil recovery (EOR) [3-6], acid treatments[7, 8], hydraulic fracturing (HF), thermogas-chemical treatment (TGCT) [9, 10].
