Abstract
The possibility of utilizing drill cuttings in the technology of building ceramics is investigated. Using the microscopic and X-ray spectral methods of analysis, the chemical and mineral composition and radiological properties of two samples of drill cuttings – waste gas drilling in the Poltava region – are determined. Using the bioindication method, it is established that the studied drill cuttings are phytotoxic and harm the environment, therefore, they need to be disposed of. According to the radioactivity, the cuttings are investigated, they belong to the materials of the 1st class, which allows using them without restrictions in the construction and production of building materials. The main ceramic-technological characteristics of the cuttings are determined. It is established that one of the cuttings in its composition is pre-burning and burning properties similar to clay rocks, the second cutting is unsintered psammite- aleuropelite material with a high content of calcium and magnesium carbonates, quartz and feldspar. The fundamental possibility of using the studied drill cuttings as the main raw material and mineral additives in the compositions of the masses to obtain wall ceramics with the necessary consumer properties is established.
Highlights
The activity of oil and gas companies inevitably leads to anthropogenic impact on the environment
The negative impact of drill cuttings on the environment depends on their toxicity, which is due to the amount of contaminants used to prepare the drilling fluid
An analysis of the chemical and mineral composition of drill cuttings shows that both wastes are aluminosilicate materials with a high content of iron oxide
Summary
The activity of oil and gas companies inevitably leads to anthropogenic impact on the environment. The negative impact of drill cuttings on the environment depends on their toxicity, which is due to the amount of contaminants used to prepare the drilling fluid. Most of the existing methods for the disposal of drilling waste comes down to their disposal in specially equipped barns or located directly on the territory of the drilling station. Such storage of drilling waste has a negative effect on all components of the natural environment and leads to an alarming increase in the volume of their accumulation, in the absence of the necessary scale of their utilization and processing, and causes the withdrawal of land resources for a long time [2]
