MS-215 type large diameter wire line core barrel and its application in CBM well

TANG Sheng li,LIU Feng qin (Xi′an Branch,CCRI,Xi′an 710054,China)  
This wire line core barrel is researched and produced to meet the needs of fast and safe coring in coalbed methane wells.In this paper,the design thought,structure and result in the field of the barrel are introduced.The results show that the barrel is of reasonable design,dependable mechanism,high core recovery,large core diameter and high coring extracting speed.
