Testing and Research on the Combined Drilling Technology

Yong Zhang

Abstract

Combined drilling technology is a multi purpose drilling method which is developed to increase the comprehensive drilling efficiency in different formations. It combines the RC drilling with the diamond wireline coring drilling and uses the same drilling pipes and tools to realize several drilling methods adapted to its formations according to the engineering environments and geological requirements and so on. The processes of the combined drilling technology research, field testing and technical effects are described in the paper.
