Results of experimental and industrial work of the module for stream determination of the chemical composition of cuttings by x-ray fluorescence analysis

The aim: to present the results of the implementation of the technological project of Gazprom neft company group in cooperation with Nosov Moscow State Technical University on the creation of a module for the flow measurement of the chemical composition of drilling mud by the XFA method.

Matherials and methods. The selection and study of сuttings during drilling is an important, integral part of geological and technological research and the collection of geological information to study the lithological characteristics of the section and signs of oil content in it. At the same time, information on the chemical composition of the drilled rocks can be obtained only after special preparation of the selected samples of cuttings and their laboratory analysis, which excludes the possibility of its operational use during the construction of wells. Therefore, the development of this technological solution is an urgent task that requires an operational solution.

Results. The article provides an analysis of the possibility of stream determination of the qualitative and quantitative content of elements in the drilled sludge by the XRF method on the CON-X 02 spectrometer with indication of the detection limit and relative error. And analysis of the results of determination of the elemental composition of the cuttings at well Gazprom neft company group of Companies in the range from 3673.2 m to 4921.2 m using the module of flow measurement of the chemical composition of drilling mud by the XFA method.

Conclusion. The efficiency of the developed module for the flow measurement of the chemical composition of drilling mud by the XFA method in industrial operating conditions and the potential effectiveness of its application have been proven.
