| description | Relevance. The active small and medium/sized oil deposits with hard-to-recover reserves involvement in the development in the context of oil production decline in highly productive oil fields in this country is largely determined by a justified choice and creation of new innovative technologies allowing ensuring these fields' operation profitability. In this regard, the actual task is to create a set of various algorithms based on the deposits being in operation for a long time development experience generalization, allowing selection and justification for the use of best practices in other geological and field conditions, taking into account the specifics of new facilities, and from the time of the field's being out of exploration. The aim of the research is to develop an algorithm for evaluating the effectiveness of measures aimed at improving the efficiency of the primary and secondary penetration technologies, the bottom hole formation zone and the bed treatment in various geological and field conditions to justify their employment and reduce the risks of inefficient decisions making on the basis of the field data generalization. Methods. Discriminatingly, the authors have carried out a geological and field analysis and generalization of well production data for conditions of different groups of wells in the West Siberian oil and gas province oil fields. Using the methods of mathematical statistics and probability theory, they studied the dynamic pattern of the bottom hole formation zone clean-up degree and the well production coefficient according to the actual production data taking into account a nondimensional time. Results. We obtained the models underlying various algorithms for evaluating the effectiveness of formation exposing and impact on well bottom/hole zone for oil extraction intensification, reduction of the products cost and profitability increase when introducing into exploitation and further development of fields with hard-to-recover reserves. Conclusion. The obtained results, methods and algorithms allow improving the efficiency of innovative technologies application assessment and searching for technological solutions and substantiation aimed at expanding the use of resource base of the deposits on the border of economic feasibility. |
