The Research Witch is Using the Coring Tool of Wire-line Coring Drilling to Improve the Coring Rate in the Trip Coring Drilling Technology
Geological core drilling is the most direct and effective means to explore the reserves of strata containing ore,and the core extracted is an important physical geological data for studying and understanding underground geology and mineral resources.At present,the coring technology used for core is mainly wire-line coring drilling and the trip coring drilling,but both of them have certain requirements on formation lithology,and their applicability is poor in some difficult strata.In this paper,by combining the common advantages of rope drilling technology and common drilling technology,the wire-line coring drilling tool is applied to the trip coring drilling,and through field application,it is determined that this method of coring drilling has a positive role in improving the coring rate.
