| Summary |
|---|
The subject gives basic information about special drilling technologies used in drilling practice. First of all, the attention is intent on these special drilling activities.
Directional drilling, basic directional well types – characteristics.
Horizontal drilling – modern technology of borehole drilling – technical means
for directional and horizontal drilling. Turbines (turbodrills) and downhole
motors. Measuring technique used for orientation of well axis course.
Inclinometers – measurement methods and constructional workmanship.
Measusrement while drilling – MWD and LWD systems (LWD – logging while
drilling). Multilateral drilling and re-entry drilling – determination of oil
and gas reservoir recovery inerease. Coiled tubing drilling technology -–CT
technology. Slim hole drilling. Underbalanced drilling – UBD technology.
Drilling by use of top drive system – TD drilling. Some of modern geotechnical
unconventional drilling methods and deposit mining. Rotary – percussion
drilling by use of down – the – hole hammers. |
| Learning Outcomes of the Course Unit |
|---|
| The main goal of this subject is to make students acquainted with the special drilling activities, used in the contemporary drilling practice. The students have to gain basic knowledge which makes them possible to define individual types of special drilling works, to describe them and outline the technical means and technological processes used during the realisation of these special drilling works. On the basis of the acquired theoretical knowledge they have to demonstrate how to explain realization principle of these special drilling works and by use of practical examples to ilustrate the spheres of their utilization. They must be able to apply their knowledge in the computation and practical tutorials, to find the optimum methods of solution of tasks dated up in these tutorials by use of the categorization and analysis of the available information relating to problems of special drilling works. They have to be able to summarise the knowledge gained during the solution of tasks within the frame of tutorials by use of synthesis, to codify this knowledge and to make a proposal of the optimum solution variety. Last but not least, the have to learn how to judge the importance of the information, to diferentiate between material and immaterial and to conclude and choose these important data which are utilizable in their next professional activity. |
