Tooling materials science| Zusammenfassung: | Purpose. The work objective is to increase the efficiency of insulation work through the use of thermoplastic mixtures insoluble in the well fluid.
Methods of research. The tasks were solved by a complex research method, including analysis and synthesis of literary and patent sources, conducting analytical, experimental studies.
Findings. A method of isolating absorbing horizons by thermoplastic materials has been developed and substantiated, for the implementation of which it is necessary to perform the following technological operations: delivery of thermoplastic materials to the bottom hole, melting of thermoplastic materials and crushing of thermoplastic materials into absorption channels.
Practical implications. For various geological and technical drilling conditions, technological isolation schemes of absorbing horizons of thermoplastic materials are proposed. The use of household waste based on polyethylene terephthalate has been proposed as a cement material for isolating absorbing horizons of boreholes. |
