Title: Application of PDC bit and double tube swivel drilling techniques in west of Henan bauxite strata
Abstract: In the paper the authors analyzed and discussed the drilling technology in bauxite strata, through the comparation of conventional rope core drilling, normal twin pipe drilling and drilling PDC double. Conventional drilling method could not solve drill hole wall adhesion and sticking problems, often making drilling with low efficiency. While PDC bits and double pipe drilling can better solve the adhesion of the hole wall and the sticking of problems, improving drilling efficiency.
