Experience of applying the shock wave impact method for the bottomhole zone

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.

In the course of the research, an analysis of the development of geological and technical measures at various fields was carried out. The justified application of these measures has been studied, and recommendations have been made to increase the efficiency of oil recovery based on drilling wells with modified valve assembly parameters. The conducted research allows us to obtain optimal performance indicators of pumping equipment associated with such parameters as pressure, flow, taking into account the lowest cost of repair work. For this purpose, modeling of geological and technical measures based on drilling a well with modified parameters of the hydraulic assembly of the drilling pump has been developed. This design solution allows you to obtain optimal performance of the drilling pump, taking into account the lowest costs for current and major repairs. These studies aimed at finding optimal geological and technical measures (GTM) related to increasing the productivity of drilling pumps and oil recovery in general are very promising and relevant.

“…At the second stage, the oil reservoir is aged to achieve a uniform temperature distribution in the reservoir. At the third stage, the formation is filtered, which helps to increase the filtration period of the product with a reduced viscosity coefficient [5][6][7].…”

Numerical solution of the problem of thermal effects on high-viscosity oil through a horizontal well

et al. 2024

In this paper, the problem of developing a high-viscosity oil reservoir due to the effect of paragravity based on heating the reservoir section between the injection and production wells is considered. The thermal effect on the formation reduces the viscosity coefficient of the oil and increases the mobility of the raw material. The heat transfer equation is solved by the PSSS method. The task is solved in three stages. At the first stage, the oil reservoir is heated, at the second – its exposure, at the third - filtration.
