Title : BUILDING MATERIAL AS DRILLING CUTTINGS RECYCLING PRODUCTS

Abstract :

The drilling of oil and gas wells is associated with the formation of a large number of drill cuttings that have a significant toxic effect on the environment. The degree of toxic effect depends on their content and properties, which are mainly determined by the characteristics of the drilled rock. The article presents the technology of drilling mud utilization with obtaining inert building material that complies with established standards, which is environmentally and economically viable. Research and measure The exercises were carried out according to GOST methods. According to the results of measuring the grain composition, the control sample was assigned to loose sand, and the inert building materials obtained were classified as cohesive sand. Building materials had a higher density compared to the control sample, which was associated with a decrease in the moisture content of the material, as well as with the addition of natural sorbents. petroleum products of all studied samples is insignificant. The pH index in materials using gypsum had the lowest values of 8.90 pH. Materials using quick lime had a maximum result of 11.60. The maximum concentration of sulfates was observed with gypsum, which is due to an increase in the products of the metabolic reaction. All the samples cited do not exceed 1,500 Bq / kg - the norms for the content of natural radioactive nuclides in building materials. In general, all the obtained processing options comply with the requirements for building materials, are safe from the point of view of environmental friendliness and can be used for their intended purpose. The residual oil content of all the samples studied is negligible. The pH index in gypsum-based materials had the lowest pH values of 8.90. Materials using quick lime had a maximum result of 11.60. The maximum concentration of sulfates was observed when using gypsum, which is due to an increase in the products of the exchange reaction. All of the samples cited do not exceed 1500 Bq / kg - the norms for the content of natural radioactive nuclides in building materials. In general, all the processing options obtained comply with the requirements for building materials, are environmentally friendly and can be used for their intended purpose.
