Analysis reveals the ecological impacts of acid hydraulic fracturing on rock compositions, suggesting growth in environmental protection technologies.
The materials of the article consider examples from a review of modern technologies for studying the environmental protection possibilities of integrated processes of sustainable development of acid hydraulic fracturing. The impact on the composition of rocks occurs not only due to the high pressure and speed of injection of the fracturing fluid, but also due to chemical reactions of the acid with the rocks. Acid treatment of the rock is used in both carbonate rocks and sandstones. In sandstones, acid treatment of the matrix is aimed at dissolving particles that pollute the bottomhole zone of the formation and perforations. Theoretically, the acid is filtered into the porous medium, dissolving solid particles in the pore channels that impede the flow of formation fluid, so the acid dissolves particles in the pores, pore channels and along the pore surfaces. Data analysis in geology as an environmental component of acid hydraulic fracturing was carried out taking into account step-by-step action algorithms in accordance with the developed regulatory and technical documentation.
