The Research and Application of Deep Hole Core Drilling Equipment for Wenchuan Earthquake Fault Scientific Drilling Project

Abstract:

Deep hole core drilling equipment, including KZ3000 drill rig, high-pressure mud pump and wire-line coring rods and tools, is the first scientific drilling system in China, which was independently designed and manufactured to meet the needs of Wenchuan earthquake fault scientific drilling project (WFSD). The equipment is set fully hydraulic, high-speed top drive, large diameter and deep coring in one, featuring good comprehensive capability, wide process adaptability and high intelligence of manipulation. During the WFSD-2 deep hole core drilling, it worked well by meeting the design requirements in all functions. As stage innovations for deep drilling equipment, it has a potential market value in scientific drilling, deep prospecting and shallow oil and gas drilling.
