CN201908597U 一种绳索密闭取心工具 失效 - 权利终止

一种绳索密闭取心工具
摘要：
本实用新型涉及石油与天然气钻井工程取心领域，特别涉及一种绳索密闭取心工具。该实用新型的安全接头(1)与六方总成(2)、六方总成(2)与外筒(3)、外筒(3)与取心钻头(4)均为螺纹连接，打捞总成(5)与悬挂分流总成(6)、悬挂分流总成(6)与压力平衡接头(7)、压力平衡接头(7)与内筒(8)、内筒(8)与割心总成(9)均为螺纹连接，打捞总成(5)、悬挂分流总成(6)、压力平衡接头(7)、内筒(8)、割心总成(9)和密封总成(10)整体悬挂于六方总成(2)上。本实用新型实现了在取心过程中不需要重复起下钻具，因而提高了钻井时效，节约钻井成本。克服了现有密闭取心技术每次取心都必须重复起下钻具的不足。
摘要（英）：

The utility model relates to the field of the coring of petroleum and natural gas drilling engineering, in particular to a sealing coring tool of a rope. According to the utility model, a safety joint (1) is in threaded connection with a hexagonal assembly (2), the hexagonal assembly (2) is in threaded connection with an outer barrel (3), the outer barrel (3) is in threaded connection with a coring drill bit (4), a fishing assembly (5) is in threaded connection with a suspension distribution assembly (6), the suspension distribution assembly (6) is in threaded connection with a pressure balancing joint (7), the pressure balancing joint (7) is in threaded connection with an inner barrel (8), the inner barrel (8) is in threaded connection with a core cutting assembly (9), and the fishing assembly (5), the suspension distribution assembly (6), the pressure balancing joint (7), the inner barrel (8), the core cutting assembly (9) and a sealing assembly (10) are integrally suspended above the hexagonal assembly (2). The sealing coring tool of the rope does not need to repeatedly trap a drilling tool, so the drilling efficiency is improved, and the drilling cost is saved, and the defect that the existing sealing coring technology has to repeatedly trap the drilling tool every time is overcome.
