The development of efficient drilling tools tailored to the unique geological conditions of Kazakhstan's drilling sites is paramount for optimizing well construction operations. This study focuses on the design, fabrication, and evaluation of a combined spud bit specifically engineered for drilling technological wells in Kazakhstan. The combined spud bit integrates both polycrystalline diamond compact (PDC) and carbide cutters within a single robust structure to enhance drilling performance across a diverse range ...

The optimization of technological processes is vital for advancing scientific and technical progress in exploration activities, particularly in drilling operations. The integration of operating microprocessor equipment and automated management systems has opened up new opportunities for theoretical research in optimization processes and drillings. Control systems for drilling exploration wells on solid minerals enable real-time operation and data collection, processing, and diagnosis of equipment functionality. Op...

A comprehensive study of composites using traditional methods of testing mechanical properties in combination with methods of digital optical and scanning atomic force microscopy made it possible to establish stable correlations between the content of chromium diboride CrB2 additive with an average grain size WC, microstructure parameters, hardness, fracture toughness, ultimate strength at bending and compression. The optimal ratios of the components of the WC–Co-CrB2 system have been established, at which a finel...

The drilling muds parameters are playing a major role in drilling technology and particularly in oil and gas drilling technology. At present those parameters are measured manually at long and irregular time intervals. In Satpajev university a general method of the existing manual measurements automatization has been worked. A number of patents on appliances for automatic continuous measuring the drilling mud funnel viscosity, density, jell stress and other parameters was obtained. Engineering development on creati...

The power and energy parameters of paddle drills used for drilling geotechnological wells in the extraction of uranium raw materials are considered. The distributions of the axial load, rotational force, and power for all rock-cutting elements of drills are obtained. A comparison of the cost of power for the destruction of the bottom of the well using a well-known and patented picobur equipped with a ring pilot showed that picobur of a new design during drilling reduces energy consumption by 14-17% due to a more r...

A mechanism of core blocking that is drilled out during the coring from deep wells in the direct and indirect flushing with drilling mud is examined. Using methods of technical mechanics and hydromechanics, a formula for flow rate excluding a core blocking is obtained during the backwashing. The value of necessary flow rate depends on not only a direction and intensity of fracturing of rocks, geometrical and density parameters of core pieces, but also on structural strength of drilling mud. A mechanism of core sel...
