Technological feature of hypan-acid treatment

Recently, there has been a tendency in the Russian Federation to reduce the design values of oil recovery, the main parameter characterizing the rationality of field development. In many ways, the decrease in question is due to the development of the most productive deposits discovered back in Soviet times. To maintain production levels in mature fields, it is necessary to apply various methods of increasing oil recovery (MIOR). According to many experts, one of the most effective ways to increase oil recovery are methods aimed at increasing the reservoir coverage ratio and displacement coefficient by pumping various chemical compositions into the productive reservoir. Thus, when using various physico-chemical methods of enhanced oil recovery (PCMOR), it is necessary to conduct preliminary assessments of their effectiveness. Due to the comprehensive analysis of field data on several fields in Western Siberia, the main geological and technological parameters that most affect the effectiveness of the measures are highlighted in the work. Based on the selected characteristics, using geological and statistical modeling, a methodology for predicting the specific effect of PCMOR MIOR treatments has been developed.

This article presents a study on hydraulic fracturing as one of the most effective methods of increasing the flow rate of wells, namely, the importance of evaluating the geometry of a hydraulic fracturing fracture when designing in difficult geological conditions is considered. The quality and success of the event depends on the correct assessment of the predicted crack geometry and the volume of the injected proppant. The fracture geometry is influenced by the mechanical properties of the rock, so, in the article, the results of a study of the mechanical properties of the core by dynamic and static methods are presented, and the main characteristics of the dependence are given. The results of modeling the fracture geometry of hydraulic fracturing at the stage of analysis of mini hydraulic fracturing are also presented. The findings indicate the need to use data on the mechanical properties of core samples with a high clay content to achieve more accurate predictions of the crack geometry. It is recommended to use a correlation model of the mechanical properties of rocks to account for various factors such as horizontal stress and poroelasticity coefficient. The development of new approaches to the analysis and modeling of these parameters will allow us to create more reliable tools for predicting the behavior of cracks in rocks and effectively managing the process of hydraulic fracturing.
