This research article determines the feasibility of implementing the technology of impulse-depression impact on productive Devonian terrigenous deposits, the development of which has a number of significant problems. The relevance of this work lies in the fact that the experience of developing such reservoirs is very small, which indicates little information on the use of the most effective methods of enhancing oil recovery or stimulating oil production. Within the Perm Krai, a field has recently been put into development in the Devonian terrigenous deposits. This reservoir has a complex geological structure and low reservoir properties, which leads to low productivity of production wells. In order to increase the level of oil production, the authors of the article considered the possibility of using the impulse-depression impact technology on the well bottom zone of the well to remove and clean the filtration channels from clogging particles. To substantiate the application of this technology, predictive calculations were performed in a hydrodynamic simulator, the results of which were used in the economic assessment. Based on the results of this work, a high technical and economic efficiency of this method has been revealed, which increases the potential and prospects of its implementation not only within the considered object, but also in other fields with similar characteristics and properties.
