“…where V m is mechanical drilling speed, m/s. Analysis of formula (10) shows that the first terms in brack ets depend on the position of the cutting element on the blade, i. e. on its radius of rotation R i , defined by the formula (9). The second term does not depend on R i .…”

SoMe feaTureS of DrillinG TeChnoloGY wiTh PDC BiTS Purpose. Improving the technology of drilling wells with blade bits by establishing patterns of interaction in a pair of "cutter rock" to find out the causes the "hanging" blade bits over the central part of the bottom hole and develop recommendations for eliminating. Methodology. The tasks were solved by a comprehensive research method, which includes analysis and synthesis of literature and patent sources, analytical studies of existing rotary drilling models to solve the problem of "hanging" of the blade bit. findings. It has been established that the distribution of axial load on rock cutting elements depending on the distance from the center of the blade bits is extremely uneven: the incisors located on the periphery of the bit edges experience the smallest load, and the incisors located in the central part of the bit are the most stressed. originality. It was shown for the first time that the "hanging" of the bit over the central part of the face is caused by the redis tribution of axial load along the bit blades from the minimum value at the periphery of the blades to its sharp increase to the bit axis to compensate for the decrease in the path travelled by the bit in this zone. For the first time, it was proposed to perform blade bits with sharpened blades along a radius, and to destroy the resulting core with a special device. Practical value. As a result of the research, recommendations have been developed for the design of a fundamentally new design of the blade bit, which will not "hang" over the central part of the face during the drilling process. This design of the blade bit can reduce the energy intensity of drilling.

“…In [10], the influence of various factors on the mechanical drilling rate was analyzed. In particular, it was found that with a decrease in the inclination angle of the cutting plate, as well as with a decrease in its lateral angle of the installation, the fracture efficiency increases.…”

Bit-rock interaction while drilling wells using numerical simulation methods is analyzed in the article. The effect of the location of the buttons relative to the destruction of the rock, the influence of the structure on the total speed of the drill bit was considered. The total bit velocity was investigated by comparing the results of modeling the operation of the industry bit and the optimized bit. Using methods of numerical modeling allowed creating an atmosphere of the drilling process in a computer environment, where the destruction of rock using a rock cutting tool was analyzed. Due to the pairwise positioning of the buttons in the optimized bit modeled in the ANSYS program, the number of buttons decreased by 13 pieces and the performance of the bit increased significantly. The optimized bit demonstrates more intense penetration into the rock and obvious fragmentation on the rock surface. A drill bit with a pair of buttons rotates more intensively and acts on the cross-sectional area of the rock with values greater than a bit with button of a conventional location. Rising values of the total velocity on the graph signal the dynamic movements of the rock cutting tool.
