Drilling Technology for Changye Well-1 in Shale Gas

Abstract:

The final hole depth of ChangYe parameter well-1 is 3204.72m with complex formation and long coring section. The drilling construction is elaborated in well structure, drilling tools assembly, drilling equipment, bit drilling parameters and drilling fluid. This paper mainly introduces the methods of ensuring the high coring rate and the application of potassium chloride mud system and composite drilling technologies in shale gas drilling.
