Engineering Physics Annotation << Back Modeling of a Geological and Technical Event Based on Drilling a Well With Modifi ed Valve Assembly Parameters Abdyukova R.Ya., Petrova L.V., Velieva O.V., Valeev E.R. In the course of the research, an analysis of the development of geological and technical measures at various fi elds was carried out. The justifi ed application of these measures has been studied, and recommendations for increasing the effi ciency of oil recovery have been studied. A model of geological and technical measures based on drilling wells with modifi ed valve assembly parameters has been developed and proposed, which allows to obtain optimal performance indicators of pumping equipment, taking into account the lowest repair costs, i.e. the task of increasing the effi ciency of well use through the use of an improved design of the drilling pump valve is solved. Keywords: drilling pump valve; geological and technical measures; increase in production; major repairs; operational effi ciency. DOI: 10.25791/infi zik.2.2024.1387 Pp. 40-44.
