In «Tulskoe NIGP» new production technologies of diamond bits were developed and implemented. This technologies allow improve exploitation characteristics of developed equipment and upgrade serial equipment. Examples of technological background organization of serial and modern diamond bit were given for objects «Central-Kola» expedition and geological organizations of republic Uzbekistan.
Make an inventory composition and purpose of complex techniques equipments for realization investigation works on shelf, accommodated on the swimming drilling rig.
Algorithm of projecting of deep wells construction, based on analysis of drilling of first deep wells in Norilsk region is composed. Article shows, that usage of new diamond bits improve efficiency of drilling.
The peculiarity of the method of drilling with the use of removable tools is the unobstructed movement of the tools inside the drill string.
When drilling vertical and declined wells, the volumetric tool takes the working position under the action of its own gravity. Determination of the dependence of the resistance coefficient CR, fluid resistance force FC and speed of movement of the removable tool v on its weight, length, angle of inclination of the well, viscosity of the flushing fluid and the size of the annular gap was carried out on a specially made experimental stand by the method of falling weight.
With the existing methods of drilling, the growth of labor productivity is largely constrained due to the large amount of time spent on performing round-trip operations …
