In geological exploration operations, the diversity of formation conditions often poses challenges to the use of drilling tools. When facing loose sandy soil layers, the anti-collapse design of the coring drilling tool comes into play. The special coating on the outer wall of the tool can reduce the adhesion of soil particles, while the internal circulation channel continuously delivers wall protection fluid to prevent the borehole wall from collapsing due to loss of support.
When encountering hard quartz rock formations, the bit material of the coring drilling tool becomes crucial. The bits of such tools are mostly made of high-strength alloys, which can gradually break rocks during rotational drilling. Moreover, the tooth shape of the bits is optimized to disperse the pressure during drilling, avoiding tool failure caused by excessive local wear.
When there are faults or fractures in the operation area, the flexible connection parts of the coring drilling tool show their advantages. The connecting joints between tools can adjust the angle within a certain range to adapt to slight deviations of the formation, reducing tool jamming caused by faults and ensuring that exploration operations can continue to advance and obtain complete geological samples.
