YZX130型液动锤研究及其在 WFSD -4孔中的应用
Research on YZX130 Hydraulic Hammer and Its Application in WFSD-4 Well
摘要
Abstract
This article introduces the structure and working principle of YZX130 hydraulic hammer, and summarizes its main features by analyzing the debugging and testing results.The application of YZX130 hydraulic hammer in WFSD-4 well proved that this hammer could substantially increase round trip coring length and rate of penetration, especially in hard and broken formation.However, its effect in weak and loose formation with high plasticity was relatively poor.关键词
