Abstract: The article provides information about an accident (uncontrolled explosion) that occurred during repair work on an oil well while pumping a hydroperite solution, and describes one of the possible causes of this accident with a brief theoretical justification for its occurrence. In order to confirm or exclude the considered cause of an uncontrolled explosion at an oil well, a test procedure has been developed and described in this article to determine the explosion hazard of mixtures of hydroperite solutions with concentrations of 2 % and 4 % with various fuels and lubricants at pressures of 1, 50, 100 and 150 atmospheres. According to the tests carried out using this technique, it is simulated that a hydroperite solution of concentrations of 2% and 4% is in contact with petroleum products in the pipe space of an oil well, under various injection modes of the solution. The object of the tests was mixtures consisting of a hydroperite solution with concentrations of 2 % and 4 % and various fuels and lubricants (oil samples from the field, Shell oil, MG-15V oil, Armatek grease), as well as products of their interaction and mutual oxidation. The article describes the equipment that was manufactured specifically for these tests, provides a general diagram of this experimental equipment, indicating the main components of the principle of operation of the recording sensors and the procedure for performing work on the tests. The used measuring instruments (SI) for recording and processing data received from recording sensors, the results of processing and the analysis of the data obtained are indicated. The results of the tests were summarized and summarized in the table given in this article.
