Tooling materials science| Zusammenfassung: | Established the fundamental principles of the theory and practice of electrochemical treatment of drilling fluids and their component interaction with destructible rocks in the drilling of wells.
As a result of laboratory and analytical studies of the process of electrochemical treatment of washing liquids, aspects of their internal component interaction were established. Studies of the influence of the main types of impurities during the electrochemical treatment of washing liquids revealed the regularities of the mechanism for changing the values of the surface tension of liquids depending on the pH level and the directionality of the process of changing the conductivity was established. It is proved that the influence of the environment, namely its type and component composition, which is often not amenable to direct adjustment and is determined by objective reasons, is a decisive factor in managing the process of destruction of rocks. Using the example of consideration of an elementary act of rock destruction (quartz), the fundamental principles of the theory of interaction in the "activated cleaning agent - rock" system are determined. The necessity of electrochemical treatment of drilling fluids during drilling operations has been proven.
The physico-chemical properties of the environment in which the destruction of rocks occurs actively influence the course and direction of the downhole processes, the main of which are adsorption, which are completely dependent on the chemical and ionic composition, and are also determined by the electrophysical and crystal chemical characteristics of the rocks being destroyed.
The obtained results of laboratory and analytical studies are basic for the design of operational parameters of the process of electrochemical treatment of drilling fluids in order to achieve acceptable technical and economic indicators during well deepening. Data on the study of the influence of various types of impurities on the performance of the process of electrochemical treatment of washing liquids constitute the basis for further research work on the development of advanced formulations of cleaning agents. |
