Tooling materials science| Zusammenfassung: | Purpose. Unbiased analysis and consistent calculation of individual positions of the complex technological regulations for the implementation of drilling operations. The specified regulation is based on the constancy of the technical and economic indicators of well drilling and the safety of performing the main drilling and auxiliary operations. Drilling operations are associated with the use of jet jets to intensify the destruction processes at the bottom of wells, which are constructed in the rocks of the soft and medium complex according to the strength parameters.
Methods. The presented results of experimental studies of the features of drilling operations are associated with the use of jet jets to intensify the destruction processes at the bottom of wells. These works were carried out with the involvement of modern methods of analytical analysis and relevant laboratory and bench studies, in particular, by using the general principles of mathematical and physical modeling, methods for processing research results, instrumentation and materials. The flow of hydraulic drilling downhole processes was modeled on experimental wells using drilling rigs, as well as appropriate tools and equipment.
Findings. Some formal features of widely used mechanical rotational methods of deepening bottomholes are outlined with the definition of the features of their technical and technological support in various geological and technical conditions. Separate structural elements of the technology for the production of borehole destruction processes using the phenomena of hydromonitor disintegration of the rock mass have been developed. The fundamental principles of the constructive construction of a laboratory base for the study of hydraulically activated jets of drilling fluid and the corresponding downhole tool – a hydraulic drill are presented. It has been analytically and practically proved that the efficiency of the mechanisms under consideration is largely determined by the adequacy of the obtained preliminary design parameters of hydraulic fracture. Moreover, such parameters are a derivative of the physical, mechanical and chemical properties of rocks (drilling fluids), and the characteristics of the equipment used, technological tools, etc.
Originality. A fundamentally different implementation of the interacting working units of the proposed hydraulic drill and the flexibility of its surface control mode ensure the implementation of the program for the effective directed destruction of the rock mass by hydro jets with the possibility of prompt adjustment of the hydraulic power characteristics of the active flow, as well as dimensional compactness relative to the overall dimensions of wells of different classification groups.
Practical implications. Separate components of an improved technological methodology and the corresponding technical support for performing well operations using the effect of hydraulic destruction of a rock mass based on modern progressive industrial principles and high economic indicators have been created and substantiated. The general and basic design characteristics of equipment and tools for performing work related to the adaptation of jetting phenomena to specific well conditions are presented. The data obtained are the basis for further developments to improve the quality and reliability of drilling and related operations when drilling wells using the basic principles of hydraulic destruction of the rock mass. |
